Statistics and Lifehacks

Singingly, many people have previously stumbled upon the NFC acronym. We know about the fact that NFS is on the phone, as well as about the features of it on Android.

NFC – what is it?

Previously, this technology was most widely used for contactless payments in the sphere of trade and transport services. Today there are active developments in the mobile area.

Mayzhe Kozhen Vedomy equips its devices with NFC modules. Therefore, we can use our mobile phone to communicate with various electronic devices, for example, if we are stuck with a payment system by installing a special program. Whose interest in these data is high.

Thus, our mobile device today can be used not only for communications, but also for transmitting and receiving information, paying for purchases and obtaining receipts for transport.

We have the right to earn a virtual payment card or a pass to any business.

In addition, it is easy to access NFC tags and smart cards, and also quickly exchange information.

At the moment, the mobile industry has different understandings that many people don’t feel. This is entirely due to the need to understand certain nuances. Well, since you have read about NFC, it means that you have had a chance to come across this concept in some way. Please contact us in the new report.

The technology of high-acidity, dart-free communication with a small radius of action (no more than 10 centimeters), which allows for contactless exchange of data between a pair of devices that have a handle: for example, between a plastic a smart card or a mobile phone and a terminal that reads. NFC technology is based on radio frequency identification, which is a method of identifying objects in automatic mode. When a radio signal is detected, it also helps to record and read data that is stored in transponders, often used as NFC tags. In general, we can talk about the technology of transmitting information via another radio channel, which supports active and passive devices. For example, Sony NFC key fobs do not require any additional equipment to ensure their operation, and the smell is completely passive.

Features of technology

Well, if we are talking about NFC, then let’s take a look at the three most popular options for using this technology in mobile phones:

reading mode, in which phone can read passive tags, for example, for interactive advertising;

Emulation of cards, if you have a gadget built to “pretend” to be a card, such as a payment card or pass;

P2P mode, when there is a pair of two phones to exchange data.

Most often, NFC technology transfers the chip to a mobile phone, as well as to many devices, both individual and at the same time inseparable from its owner. In this case, you may be asked to accept a payment method, which is permissible in the presence of a virtual card, a key, a card for identifying the cardholder, a bonus card, and much more.

Vikoristannya Sphere

Well, NFC on phones - what's that? In this regard, it is important to note that at the moment similar solutions have become widespread and actively pursued in many areas. For example, using this technology, the reservation of electronic receipts and their sales, payment for car parking and public transport are carried out. NFC tags are actively being used in the areas of service development and service, security and access control.

Assigned to Bluetooth

These two technologies are similar in principle, but there is a great difference between them. If you look at what NFC is, you will notice that the main advantage of this technology is the short connection time, which is one tenth of a second. A small radius will prevent this method of transmitting data from being stolen. However, NFC maintains a data transmission speed of 424 kbps, which is much lower than Bluetooth.

Current stage of development

Technologies for contactless payments have now become even more advanced, which has led to the emergence of cards such as MasterCard PayPass and Visa PayWave, which are equipped with built-in antennas and have the NFC function. This market has become so guilty that now companies such as MasterCard, Google, Sprint, Citibank and First Data have created a service under the name Google Wallet, which is installed on a number of Android smartphones. With additional programs, you can easily convert your gadget to a credit card, which allows you to make payments at any terminal that works with PayPass support.

What is NFC and how are tags used?

The tags in this category are small programmed information zones that will appear in billboards, posters, or on product displays in general merchandise stores. If you click on one of them, you can find additional information such as web addresses, maps and movie commercials.

p align="justify"> The process of working with tags transfers the sequence of actions to extract the information contained in them.

What you need to do to scan marks

I’ll first check that the NFC function on the phone is turned down and the screen is active. Place the phone over the tag in such a way that it touches the NFC detection zone. Next, the device will scan the mark, and then show you instead of removing it. Then click together and you will see the label.

How to transfer a music file via NFC

To begin with, you need to reconfigure that the necessary function on the phone and device is turned on, and the screens of both gadgets are active. You can open the music player by going to the main screen, where the “Multimedia” item will be selected, and then the “Music” icon. If the rest is not displayed, then touch the “Advanced Screen” symbol, and then “Music”. To open your media library, you will need to go to the “My Music” tab. After selecting a music category, you can proceed to selecting a track to play on your other device. You need to tap it to complete it, and then press pause. The broadcast is active whenever a track is created or paused.

The transmitting and receiving phones must be turned with their reverse sides one to the other so that their NFC recognition zones overlap. Once the connection is established, the device will vibrate, and then the broadcast will begin. After vibrating the machine, remove the trace from one to another. This prevents attempts to connect again, which could interfere with the transfer process. When the process is completed, the receiving phone will create the received file automatically. This entry will be saved to your email account immediately.

Important moments

Well, as we talk about NFC, we also have to say about the presence of special aspects that can be called the “dark side” of this technology. While the help of NFC makes it easier to take care of a lot of everyday tasks, it also makes life so much more complicated, as one can see at the sight of security. This technology works exclusively in close proximity. If you do not use NFC to ensure your safety, you can enable it. In this case, all your confidence simply knows, which allows you to exploit other methods. Leave everything here and adjust your smartphone. If you treat the device like a mobile gadget, but do not protect it with anything, you may end up with problems. Unfortunately, you won’t be able to send your security via a PIN code if you have NFC on your phone. What does it become understandable if the evildoer is accelerated by your lack of turbochargedness?

Warto identify such a scenario as theft of a phone. That person, who knew or stole it, can vikorize all payments and functions. However, here you must be a realist, even though you can spend the keys to an apartment, a car, or a resident, which is connected with such insecurity. NFC tablets are safe, as you know.

First devices

NFC support first appeared in phones released in 2006. However, such a function turned out to be absolutely unnecessary and undemanded, since at that time there was no infrastructure. The NFC module is currently equipped with the serial smartphone Sony Xperia S. This device is equipped with a dual-core processor and a 43-inch HD screen. It works under the operating system of Google. Android-NFC is in no way different from a similar function on other platforms. This device comes with two NFC tags called XPERIA SmartTags, which allow you to program the device to launch certain operations within range, for example, turning on the navigator or connecting Wi-Fi.

Intel has already taken up significant power issues related to the integration of NFC chips into next-generation Ultrabooks, and thus ensures that this technology is well on its way.

The birth of the future

Well, if you look at the NFC technology (as you’ve already been using it for a little while), then it’s good to say about those who, for some reason, have a craving for it. In 2002, companies such as Sony and Phillips teamed up to develop a completely new radio communication standard, as the name goes. There have been numerous attempts to formulate similar technologies: the Phillips company created the MIFARE technology, and Sony has a similar development under the name FeliCa. Despite the fact that these technologies are not very powerful, the stench between them turned out to be absurd. Creating a standard of calls to remove all the advantages of past developments, as well as open up the possibilities for its implementation in practice.

When talking about NFC, it is necessary to remember that from its very inception, this technology was focused on effective interaction between various electronic devices, including daily communication. ednannya. How to use personal computers, PDAs, mobile phones, video cameras, and other gadgets here.

One can say about such a feature of the interaction between devices that operate under the auspices of this technology, as the connection between devices after their connection one to one to stand up close. After installing the connection, a test between devices is performed.

For example, if you bring a camera to the TV, which works behind the NFC module in both gadgets, the image transfer process will immediately begin. Both a mobile phone and a PDA are in close proximity to a personal computer, which allows for printing by synchronizing the address book or any other documents.

Method of implementation and development prospects

NFC technology is implemented on a chip that works in passive and active modes. The first option transfers information from passive devices, as well as powering it up. At the moment, you can be careful not to intensively expand this technology, but everything is ready before the world takes root. Companies such as Google and Apple are lowering their bets on it. You can already hear about iPhone NFC now that Apple products have started adding these chips. You will need to insert SIM cards from the installed chip and use them only in passive mode.

There are even bright prospects for the development of this technology through the use of mobile devices for the implementation of contactless payments. It is entirely possible that through a few fates one smartphone will replace a whole series of devices and devices.

Most modern phones, smartphones and tablets are equipped with near field communication. This will help you pay for contactless payments and exchange various files with other similar devices. To take advantage of the basic functionality, you need to know how to enable NFC on Android.

Description of technology

NFC is a microchip that ensures the exchange of data between two devices. The transmission of information only works at a small distance beyond radio frequencies. The chip is mounted directly into the body of a smartphone or tablet. The robot will be provided with a special addition, Android Beam.

Before you figure out how to enable the NFC function on Android, you need to determine whether the technology is present on the device. The presence of a chip can be determined in the following ways:

Yak turn on

Turning off NFC mode on your phone is very easy. For which you need to consistently sign up the following actions:

Do I need to enable NFC on smartphones when paying?

When making contactless payments through a terminal using an additional smartphone, you do not need to enter the program and enter the mode. The chip will automatically return to the robot when exiting the hibernation mode and unblocking.

What's NFC on a phone?– This is a technology that has been developed for making payments without cards and any contacts from the terminal. Over the years, the functionality of NFC has increased and with its help you can transfer a variety of data. To install the technology, you need to install a chip on the device and enter your bank details. Relevant before being sold out in stores, as an interactive business card or key card for access to key elements in the systems.

What is NFC on smartphones?

NFC on the phone: what is it like to buy? – There are two inputs that are directly related to the name of the technology, which in Russian stands for “nearby field communication.” The technology uses a gunless method of connection over a small area. 2 devices, in which case the same chip can exchange information with each other. The transmission distance is always centimeters. The operating principle is similar to the infrared port in older models of devices.

Today, NFC is installed on almost all mobile devices, selected by market leaders. Initially, the concept of technology is small in relation to its use as a virtual form of debit cards. Among the additional cortical spheres of the vicor that appeared this year – bypass to different settings and identification of specialness. Additional technologies will provide the ability to exchange different files sent with other content. An additional program allows you to record information and store it on a special card.

The advancement of technology began with Android 4.0; mobile platforms introduced the Beam function for exchanging files between smartphones.

We remember that there is a Bluetooth service, is there an additional function with a smaller coverage radius? Bluetooth transfer of personal data with a high level of security is not suitable, since the signal spreads far and can be overwhelmed, apparently, the risk of data theft increases. With NFC security, you can indicate when connecting with Bluetooth that you need to connect for a long time.

How to find out about NFC?

Finding out NFC on any phones is a very important task for new technologies. Not all devices have this chip, although they are being installed more and more often in today’s smartphones.

For a number of manufacturers, including Samsung, the presence of the function can be determined by looking at the sticker located on the battery. Whenever a function is evident, there will be a corresponding type of writing present due to the constant name of possibility. Other manufacturers stick a similar logo to indicate the presence of NFC.

On the smartphone itself, you can see how you can install the module for additional setup:

1. You need to go to the “Adjustment” item;
2. Next, find the column “No-rotary measures” and tap on the “More...” button to select additional parameters;

1. There is a special point for setting up NFC.

Once you have already determined that your phone has NFC, you can move on to the next step - initializing the launch of the function. Thus, the installation allowed for data exchange technologies to be used.

NFC activation:

1. Click the slide on “Options”;
2. Then go to the category “Bezrotovy merezhi” and select “More...”;
3. You will need to check the option “allow data exchange...”, the function will be available on both tablets and smartphones;
4. Android Beam is automatically activated;

1. If the enhanced Beam function does not activate on its own, you must click on it and manually press it in.

When Android Beam is turned on, a low connection is applied to the robot via NFC between devices.

How to use NFC?

If the mode is activated, it is necessary to go to the next stage - selecting technology for the required item (data and payment).

It is planned to transfer data, with respect to:

• NFC mode is required on smartphones and tablets when activated and additional functions of Android Beam;
• When blocked or in hibernation mode, data transmission is interrupted;
• when devices are connected, a special sound signal will be transmitted at the optimal location to indicate that the device has entered the NFC action field;
• It is not possible to separate the devices until the remaining data transfer occurs, which will be indicated by a special sound signal.

The transfer process itself is simple and even similar to the standard Bluetooth function. You can transfer data between any devices:

1. You need to go to the folder with related content.
2. Connect the devices with their sides, moving them side by side.
3. Follow the sound notification about finding smartphones one by one. On the smartphone screen, you will receive a notification to send the message, where you can press the button to start the transfer.
