Support for NFC technology. What is NFC? NFC in phones - what is it? How to understand what is on a smartphone, the NFC function

Today, the mobile industry has no faceless technologies, the middle of which is NFC. Most of the smart smartphones have not yet figured out this function and do not know what NFC is on the phone, why the module is needed and how to understand what the presence of wine is in the singing device.

NFC stands for Near Field Communication. In perekladі tse means "near link". The main nuance is due to a small radius of the air, which indicator should not be more than 10 cm.

This function allows you to exchange information without contact. It is important that when transferring data, the attachments were close one to one, for example, a smart card, a payment terminal, etc.

NFC is based on RFID, which stands for Radio Frequency Identification. The technology is radio frequency identification, which automatically determines the difference between objects. AT to this particular type a special radio signal is installed, which reads the necessary information, as it is stored in transponders, which are designated as NFC tags.

The main features of the technology presented are as follows:

• small size of the sensor;
• allows you to exchange any information with smartphones and passive gadgets;
• does not require a lot of energy for work;
• low speed at the moment of exchange;
• s we will need an outbuilding takes more than 0.1 seconds;
• the technology varity is small.

Through a small expansion and a small indicator of energy saving, the function becomes popular, and it is easy to install it in an impersonal outbuilding.

What is the difference between NFC and Bluetooth?

NFC on phones is often obtained from Bluetooth. Basically, it is connected with a contactless transmission and a small radius of dії. At the moment, these functions are being used by new smartphones.

Mіzh represented by technologies є serious vіdmіnnostі. The main nuance is about the speed of robots. For example, NFC works a lot more, then it takes a little bit of energy, and the success happens automatically, on the Bluetooth.

For example, in order to speed up Bluetooth, you need to turn it on, then open the list of available devices, select whether you need to turn it on if the phone connects to a new one. At the same time, for Near Field Communication it takes less than a second to start the work independently, you only need to add your mobile phone to the required gadget.

The onset of vіdminnіst polagaє at the speed of transmission. For example, NFC may have a speed of 424 kb / s, and Bluetooth, version 2.1 - 2.1 Mb / s. At the moment, smartphones are equipped with Bluetooth version 3.1, which develops speed up to 40 Mb/s.

The third vіdminnіst polagáє polі dії. For Bluetooth, this indicator should be no more than 20 cm, and for NFC - no more than 10. This is an advantage for communication, even such a small radius will become a guarantee that you will not connect to an inappropriate gadget.

Presented is communication with telephones, and other gadgets, for example, payment terminals. The receiver itself does not need a lot of space, mainly it is installed in a free space between a smartphone battery and a cover. But if the phone does not lend itself to simple parsing and you cannot marvel at the stuffing, then how to presence of NFC?

Please be aware of the callers on the phone. Often, retailers show a small emblem near the looking antennas right on the back of a mobile phone, which indicates the presence of technology. Also, the icon will be stashed at the top splicing menu of the phone.

At the moment, NFC is available for everyone android smartphones, Version of which is not less than 4.0. Another way that allows you to know about the presence of communication is to go to the office, select the column " Bezdrotovі merezhi”, and then press “Che”. If a function is listed there, put a tick next to it.

This option is also often used on cards that are used to pay for travel, or on bank plastic. Krym tsgogo, її began to wake up in by-butov technique, this includes new refrigerators with the Smart option.

From the moment the technology exits, the deacons of the coristuvach are given nutrition, as well as the ways of stosuvannya. Attachment can be practiced in two modes.

1. Active. May be, two gadgets are powered by NFC technology.
2. Passive. Vikoristovuetsya roboche field is less than one outbuildings.

Communication is presented as a chip, which works in two modes. The first appointment for the exchange of money between outbuildings. The other one was accepted to be featured on special work transfers, metro maps, too.

The most requested option is contactless payment. Link your bank card to your smartphone, and when paying, put your phone to the terminal. A similar way guarantees protection from shakhraiv. Intruders cannot intercept the signal due to the small NFC field.

You do not need to carry the card with you, you can pay in stores by adding the phone to the terminal, which supports contactless payment. How can I correct the function?

1. You are guilty of a special mother bank card, the paypass option is enabled.
2. Install the program for your bank.
3. Scroll to the entrance to the special office and go to the main menu.
4. Select NFC.
5. Let's apply the card before back krishtsi phone. It is necessary for the sensor to gain information freely.

Information exchange

Another variant of the choice is available for information exchange. For whom it is necessary to install android program Beam. This software allows you to transfer different files to another smartphone.

Do not forget that the speed of the transmission will be very small, through which it is recommended not to force important files, but fawn over the strengths, or help them.

To speed up the function, it is necessary to turn on NFC in settings. The activation point is located at the column "Bezdrotovі merezhi". Then let me know if you need it.

The last point is not recommended to change through the low speed of transmission. To send the necessary data, then add your phone to another. If the system asks for confirmation of the operation, put your finger on the screen. After the completion of the strength, you will feel a resounding signal.

Reading tags

The third way is to transfer reading marks. Yogo robotic principle is similar to scanning a QR code. It's true, the difference between NFC is not a mobile camera, but a sensor under the cover.

This function is especially beautiful for home use. The creation of high marks with the help of a special program is installed, so that you can Play market. You can write on your own specific task for a song, for example, “send a message”, “telephone”, “write a sheet” just like that.

Sered popular programs see:

• ABA NFC. Allows you to create simple recognition;
• brown software for connecting to Wi-Fi without a password so that your guests do not need to joke wireless internet and enter a password, it is enough to put it to the phone connected to the network;
• Smart Tag Maker. This addendum is only suitable for those who have smartphones from Sony.

Similar signs are passive. Tse explain to them that they do not need food for the morning information. The stench may be even a small commitment, more than enough to pick up the necessary team. The number of signs is commonly called TecTiles. For your reading, it is enough to bring a gadget, after which the team will be brought into action.

Smartphones can read data and save it. The main nuance is related to the installed special programs. Download the retailer program by launching your phone, or find it on third-party resources. Software for making notes can be paid or cost-free. Before installing the obov'yazkovo, please read the description. It is important that you vindicate the brand of your smartphone.

You can also get TecTiles like a smart card, key fobs, fitness bracelet, electronic key or stickers. Such gadgets can do more. Fahivtsі recommend not to zaoschadzhuvati at the time of the arrival of technology. The quality of communication can be high, even if it lasts enough for an hour.

Pluses and minuses of the module

In the midst of the main battles, one sees a small show of energy, a reasonable price, good fortune and security. And first of all, NFC is more likely to show up, it is necessary to become familiar with some of the nuances.

Let's take a look at the main minuses of NFC.

1. Small robotic radius. Tse to bring singing discomfort under the hour of wailing. Hocha, water hour, I'm doing this show maximum zakhist. You will not be able to create a team in a vipadkovo way, pay for the purchase too soon.
2. Uncontrolled creation of NFC modifications. For example, the distributors of "Sony" and "Haomi" took up the additional technology of transmission. The stink of independently shattering stained glass materials, as if making your work less with the gadgets of their company. In other words, in order to win all NFC options, you will have to buy smartphones of less than specific brands. This includes the installation of special add-ons in the same retailer.

Deyakі nedolіki correct step by step. The distributors do not throw away their technology, but gradually make various additional payments.

Visnovok

Today's NFC is a modern solution, recognized for the power of information. But not all smartphones support this technology. If your phone needs modifications, you can add a special antenna. Install it under the cover of the gadget, or bring spare parts to the service, so you can save everything.

The last option, which allows you to get to know NFC in a special way, is to buy a special accessory. Today, impersonal companies are proposing to bring memory cards, sims, de vbudovaniya NFC.

The breadth of NFC has not reached the opposite results, albeit not for a long time. Infection penny operations wanting to explore other areas of zastosuvannya. The main plus of modification is safety. Yogo principle of work includes vipadkovі transfers of data and pennies to other outbuildings.

A lot of readers, like to actively follow the latest in the mobile industry, knowing the characteristics of a fresh gadget ask: nfc on the phone - what is it like?

Apparently: NFC (Near Field Communication) is a uniquely important technology, which means that you can transfer data from one device to another. The best way transfer photographs, music, or charge a fee for an additional mobile building, simply not. Let's talk a report about all the possibilities of this dartless interface.

What is it?

The principle of NFC operation becomes clear from the decoding of the name - two rows of attachments behind the auxiliary can exchange these and other data, and the information is transmitted over additional radio frequencies. The stagnation of technology in the mobile industry is obvious - NFC bugs can be shared with all the content that you know on your outbuilding, with your friends and you know.

Also, the gadget can write and read NFC tags to the NFC module, which can be activated, for example, to turn on that device.

What is NFC for my mobile phone?

So far, not all devices available on the market have this module. To find out what technology your smartphone or tablet is supporting, it’s enough to look at back panel add-on - like NFC there about it will be guessed. For some devices, you can find such information on the battery.
On phones of the Sony brand and other brands, you can remember the small letter N - you can tell about the support of the NFC technology gadget. If these methods did not succeed, then just go to the setup add-on and in the "Sche" branch, look for NFC and Android Beam, as there is no such item, then your gadget is not equipped with a sim module.

How to notice

If you have changed your mind, that your smartphone or tablet can support the NSF, you can activate yoga by the next step:

• We go to Nalashtuvannya and choose Dodatkovo;
• Activated NFC for additional transfer of the child;
• If Android Beam does not start automatically, then I manually emboss it on the new one and vmikaёmo.

Yak koristuvatisya

So that the transfer of data for an additional interface could be possible, it is necessary to secure a sprat of important people:

After the change of the bagatioh, the NFC-channel is not recognized by the name swidkist, it is not possible for him to transfer a great file in such a rank, the technology is better than pidide in order to drop the contacts or the web side.

Data transfer process

The algorithm for transferring content does not depend on what you yourself transfer that kind of attachment to win. The route map for which process is coming:

Features of the transmission of current data

If you fail to send the program to your comrade deak, then the NFC module will not override the APK file, but simply edit the information, as on the phone of the party that it accepts, call out the side with the addendum in the Play Market. With web pages, the situation is similar to that of an image - the owner will simply accept the web address of the side, which is automatically displayed in your browser.
Absolutely the same scheme is used when transferring video - the replacement of the whole file is sent to Youtube, which is automatically displayed on another smartphone. Photos or contacts phone book are transmitted at a complete rozmіrі.

NFC tags

Transferring data is good, but NFC technology doesn't add much to standard tools such as Bluetooth or Wi-Fi. Another on the right is a selection of NFC tags, for the help of some kind of koristuvach, you can adjust the phone settings in one dot. It has a small NFC chip, compact pads that can be easily integrated into a poster, business card, sticker and much more.

Such chips save a small amount of data, in the capacity of which they can have contact information, web site addresses or send commands, as they will be added to the reading hour. We can list a number of tasks, which can be encoded for the help of such marks:

• Adjusting the sound;
• Screen parameters;
• Improvement of other interfaces, for example, Wi-FI and Bluetooth;
• Advice;
• Telephone rings;
• Programs and a lot of other functions.

After that, as the information was written on the label, it is enough to simply save all the data and save the button.

Payment for assistance NFC-chip

Biggest cіkavim way Zastosuvannya described technology and mobile payments, singsongly and repeatedly batted, as if at the checkout, crying, pushing the smartphone to the payment terminal. If you also want to use Apple Pay services or Android Pay, Your gadget is responsible for having the NFC function in your phone.

Most smartphones coming in 2018. operating system Android is already equipped with NFC-modules, but all the same, run into a new gadget.
Also, keep in mind that the scale of NFC will be less than large, it’s not too far to limit the functionality of your main mobile add-on, becoming an outdated option without such technology. Let’s hope, now we’ve figured out why NFC is the same and how to win in everyday life, and now your gadgets have become even more beautiful in everyday life.

If you are reading it, it means that you are happy, be kind to subscribe to our channel on, well, in one place put a like (finger up) for practice. Thank you!

Today's mobile industry is promoting core smartphones in any price category of impersonal technologies that you really need. You don’t know everything about NFC technology, but even more quiet, who doesn’t use it. The alec module is superbly important and handy.

Why do you think the essence of the "near field" technology?

It is most commonly called "near field communication" - literal interpretation of the English phrase "near field communication" or short NFC. This technology is based on the wireless transmission of information. There may be a radius of operation, so the transfer of data from the building to the annex is carried out on the window, which does not exceed 10 cm. If you say more than just my words, then for the help of NFC gadgets, they exchange money without contact. Golovnya, that at this moment the stench was one and the same at a nearby station.

NFC is an extension of the ISO 14443 standard for contactless cards. This technology has combined the interface of a smart card and reader into one attachment. Functioning at an operating frequency of 13.56 MHz. The minimum hour required to establish a connection between the outbuildings that are being exchanged is not more than 0.1 parts of a second.

The physical components that support NFC technology are more compact in size and are affected by low power consumption. Therefore, the "near field" is actively zastosovuetsya navit from the modest beyond the scope mobile outbuildings. So that the koristuvachivs do not blame the difficulties in the practice of NFC (not everyone understands which side to put the gadget on, so that the technology worked), the patching of the chip is often indicated on the extension with a special sticker.

How to understand chi є NFC your gadget?

For a small change in communication, communication wins on rich gadgets, and not only on phones: for example, at payment terminals; zustrіchaєtsya at cards, recognized for rozrahunkіv for travel; present in banking plastic. Narazі navіt began to release the pobutovu tekhnіku, equipped with the technology of the "near field", smart refrigerators.

But how to understand, what is NFC, for example, in a mobile phone?

Nasampered, varto look around the gadget itself. Often the picks on the body of the equipment cover the vkazіvka at the look of the emblem, which predicts the antennas. A similar icon will appear on the splicing menu mobile phone.

You can also look into the sewing by choosing the section “Barring nets”. Then you need to click on “Sche” - and as there is an entry to the presence of NFC, next put a tick in front of this icon to activate it.

Scope zastosuvannya NFC

Today, 3 main galleys are being installed, where “near field communication” is required:

1. Contactless razrahunki. For this, it is necessary to link a bank card to a smartphone, then put the gadget to the payment terminal to write off pennies from the account. As a result, you will not need to carry payment plastic with you. In addition, this payment method is considered one of the most secure, but NFC has a small radius. Otzhe, the evildoers can not override the signal.

Activate tsyu technology for rozrachunkiv it’s even simpler:

• the presence may have a card to the bank, so that the “paypass” mode is supported;
• it is necessary to insert a valid supplement to the issuing bank;
• after which it is necessary to go to " special office and there select the “NFC” item;
• Farther to the back cover, I will attach a bank card, so that all information on it was secured by the sensor.

1. Exchange of information. To implement this function, you need to install special addendum, zokrema, "Android Beam". It is allowed to transfer different files from one attachment to another. But don't forget that the speed of transmission via NFC is low. That's why it's better to use more power than the files themselves.
2. Reading notes. For which one it is necessary to install a special addendum. Yogo can be found on the Play Market. As a result, we take away the ability to recognize, for example, the warehouse of food products and the terms of their applicability, but only a gadget with NFC for reading the barcode of goods.

Regardless of such an environment in the field of congestion, NFC technology seemed to be more convenient. Therefore, it is now being actively promoted to budget gadgets, expanding the list with skin rock.

There is a lot of stuff about this technology, but far from everyone knows what NFC is, now a smart module is needed in smartphones, and you can bring it to the master.

Before speech, on smartphones samsung dana mozhlivist z'yavilas dosit a long time ago - more 2011 rock. Already the best Galaxy Note already including (albeit optional) an NFC adapter, just like the Galaxy S2 (I9100). And the sleepy Samsung Nexus S maw is like 2010.

What is NFC?

Outside of decryption, the abbreviation is Near Field Communication, which can be translated as “near field communication”. You need to say that the radius of the NFC antenna is really narrower than the surroundings and the sound does not exceed 10-20 cm.

This technology allows you to create a contactless exchange of data through the induction of a magnetic field, moreover, it is possible as a passive exchange (say, a card is a terminal), as well as an active one (two smartphones).

Technology is spreading widely beyond the borders mobile technologies, for example, for transport cards or cards for a pass to a closed territory, which are attached to the turnstiles.

Transfer of data

Smartphones didn’t have a lot of special NFC technology. Let's say that she allowed the transfer of data between two outbuildings with a practically mittevny priymach, the prote bula was tied to two unhandedness:

1. The speed of transmission may be on the ivnі ІCh-port.
2. The need to keep smartphones in close proximity one to one.

In such a way, as a way to transmit data, NFC unequivocally played the handful Swedish solutions- Bluetooth and WiFi Direct.

Contactless mobile payments

It’s true, the NFC support in smartphones has become a real brown thing, it’s true, it’s only with the release of Android 4.4 KitKat, de showed full support emulation of a contactless bank card with MasterCard PayPass and VISA PayWire technologies.

Previously, it was only available for smartphones on the Nexus line under the hour of using the company's software Google Wallet(Do not practice to the tune of the boundaries of the United States).

However, the launch of Android 4.4 KitKat and the latest versions of the data at the moment in the whole world has already been released enough large number programs that allow you to win a smartphone instead of a payment card.

Minor, for the help of a special software, a smartphone can be converted to payment terminal, which you can accept before paying MasterCard PayPass and VISA PayWire cards.

Perhaps, a richly functional supplement, which allows you to issue a contactless bank card or connect it already.

New card issue:

1. "Tinkoff" - overpaid MasterCard PayPass card, є possibility of simplified identification for expanding limits and payments beyond the cordon. Card selection and SMS-information - free of charge. Minus - the number of transactions history (only in SMS and with a request to hot line bank). Cashless replenishment on the website of the bank and at the rich terminals.
2. "Russian Standard" - virtual MasterCard PayPass without identification and with low limits. When paying for the marne cordon. Є history of transactions.

Also, you can take discount cards from various stores from the addendum without the need to carry them with you.

It is possible to work on a routinized smartphone (there is a warning about the discovery of validity).

This program also allows you to pay for purchases of smartphones for the help of VISA PayWire. To activate payment via NFC, the smartphone is to blame for the mother's clean, unrooted firmware.

With the identification of the “Standard” equal, payment for goods and services beyond the cordon is more available.

The function of contactless payment appeared in our Android app recently. When activated, the generation of a green contactless card is generated, which is attached to the card. The next hour of payment is debited from the main balance.

Possibility of a robot on smartphones active mode root.

"Corn"

At the supplement for the popular Russian payment system It is also a support for contactless payment, moreover, the Kukurudza cards themselves are issued on MasterCard plastic, then a virtual NFC card as an add-on - VISA PayWire.

In order to speed up contactless payment from an addendum, a koristuvach can have a map active"Kukurudza" that unrooted smartphone. It is significant that this function may not work Chinese smartphones s NFC, as if the program thinks of a “wonderful” system, as it was modified (it was tied up from the wild curvature of Chinese firmware).

Mobile supplement to the bank "Russian Standard"

This addendum can issue a contactless card for payments, and it is not obligatory to be a bank client. However, the possibility of identification for essential clients is daily, so the card is already bordered by limits and it is not possible to pay for the borders of Russia.

Mobile Privat24

This addendum can be adjusted for native smartphones with NFC from Ukraine. For bank customers, a virtual card is created for contactless payments for an additional smartphone. The card is attached to one of the main accounts of any currency.

Emulation of electronic documents

Current cards for public transport (for example, the Moscow metro) are often based on NFC technology itself. So for help special programsїх you can easily copy and paste the smart phone instead of the data.

Other options

Smartphone from pidtrimkoyu NFC module can be used as a terminal for reading / writing contactless cards. Use programs that allow you to unlock the smartphone screen using a contactless smart card.

Bigness current telephones, smartphones and tablets are equipped with a chip to communicate with the neighbor. For this purpose, payment for contactless payments, exchange of different files with other similar devices is required. Chob to winkoristy korisnі functionality you need to know how to enable NFC on Android.

Description of technology

NFC is a microchip, with the help of which it is possible to secure the exchange of data between two outbuildings. The transfer of information is limited to small vіdstanі for radio frequencies. The chip is mounted directly "in the body" of a smartphone or a tablet. The robot is taken care of by a special add-on Android Beam.

First of all, in order to enable the NFC function on Android, it is necessary to indicate the presence of technology on the device. You can determine the presence of a chip in the following ways:

How to notice

Turning on the NFC mode on your phone is easy. For whom it is necessary to follow the visconaty like this:

Is it necessary to enable NFC on smartphones at the hour of payment?

When making contactless payments through the terminal for the help of a smartphone, it is not necessary to log in to the program and use the mode. The chip automatically restarts the robot when it exits the sleep mode and removes blocking.
