Nfc does not read the troika card. NFC tags: the first experience of use. All Galaxy smartphones with contactless technology

The NFC chip is equipped not only with flagships, but also with phones of the middle and low segments. A full rating should cover models of all categories. Next - TOP smartphones equipped with an NFC chip and contactless payment technology Google Pay, Samsung Pay or Apple Pay.

Flagships

Top smartphones are on everyone's lips - at the end of 2018, cool powerful gadgets with NFC came out. The following models turned out to be the best.

1st place - Huawei P30 Pro

The world's best camera phone, ranked #1 by DxOMark. Also here is a new OLED display, reverse wireless charging, an under-display fingerprint scanner, and a 7nm HiSilicon Kirin 980 processor.

NFC in this phone is just one of many features that is taken for granted. Against the background of the rest of the flagship chips, the banal NFC looks too simple.

• Water resistant IP68.
• OLED screen with infinite contrast.
• The world's best 10x hybrid zoom camera.
• Fast charging with 40W adapter + solid battery life.

For less money, the Huawei P30 is available on the market - also a cool smartphone with NFC, a TOP camera and hardware.

2nd place - Huawei Mate 20 Pro

The main feature of Huawei Mate 20 Pro is a 3-module camera with a large main sensor (1/1.7 inches), as well as additional ones with wide-angle and telephoto lenses. The phone is equipped with a 6.4-inch Amoled matrix and HDR support, IP68 water protection. Of course, there is an NFC chip + support for Google Pay contactless payment, and all this allows you to put your smartphone in 1st place in the rating.

• A revolutionary camera that easily outperforms its closest competitors, the iPhone XS and Google Pixel 3, in terms of image quality.
• 7nm processor with 5G support.
• OLED-matrix with almost infinite contrast and maximum black depth.
• 4200 mAh battery + fast charging support. Includes a 40W adapter that charges your phone from zero to 70% in 30 minutes.
• Expensive gifts when buying from the official Huawei store, including watches.

• High cost at the start of sales.
• The curved display is a controversial decision. Users highlight frequent false clicks.
• Slippery body - tends to fall out of the hands.
• Inaccurate responses of the face scanner. Still, the technology works better in the iPhone X and XS.
• Software glitches. For example, when switching to gestures and disabling navigation buttons on the desktop, shortcuts disappear.

• + examples of photos on the camera

3rd place - Samsung Galaxy S10, S10e, S10+

The entire series of South Korean S10 phones received NFC chips and is fully in line with the trend of 2019. Here are the world's best Amoled matrices with support for the HDR10 + standard, which has never been seen before in the mobile world.

Plus, smartphones are equipped with 8nm Exynos 9820 processors, cool cameras that are inferior in terms of shooting Huawei P30 Pro and Mate 20 Pro. Fast, wireless and reverse charging is available on all phones in the Galaxy S10 series.

I will add that here S10e is the cheapest smartphone, S10 is more expensive, S10 Plus is the most expensive. .

4th place - Xiaomi Mi 9

The new flagship of the Chinese brand Xiaomi surprised - at a fairly affordable price, the company created a powerful device based on the Snapdragon 855 processor. It took 1st place in the Antutu rating, which makes it the most productive Android device in the world, at least in April 2019.

Cameras 3 - with a regular, wide-angle and telephoto lens. Moreover, the main one received a Quad-Bayer filter, which allows you to combine four pixels on the matrix into one, which seriously improves the quality of shooting. In the DxOmark ranking, the phone took 5th place - it is inferior to Huawei P30 Pro, Mate 20 Pro and Samsung S10 in terms of photography.

But for little money you get NFC, a cool Amoled screen with a fingerprint scanner, high autonomy and the best processor in the world. More details in .

5th place - iPhone XS and XS Max

In addition to Huawei, Apple managed to create a new 7-nm processor - it was called A12 Bionic. This is a revolutionary chipset that outperforms the Kirin 980 and even more so the 10nm Snapdragon 845.

In addition to cool hardware and improved rear cameras, the iPhone XS is no better than its predecessor, the iPhone X, but it costs significantly more. Of course, thanks to the Apple A12 Bionic processor, the new flagships are the most powerful mobile platforms on the market. Plus, there are really cool cameras and record-breaking bright Amoled matrices with infinite contrast. A set of flagship technologies is included: NFC and Apple Pay, accurate and fast Face ID (improved by increased chip power and coprocessors), a record-breaking display in the iPhone XS Max.

• High-quality camera for shooting even at night. But it is worse than in Huawei Mate 20 Pro.
• The screen is large, bright and contrasty (purchased from Samsung).

• Screen burn-in due to unscrewed brightness. In XS and XS Max, most likely, the same screens are installed as in the iPhone X. There are cases of burn-in of “ten” screens, so I do not exclude that the disadvantage also occurs on the iPhone XS and XS Max. Read more.
• Cost at launch. The phone is expectedly expensive.
• The battery with intensive use withstands daylight hours.
• Support for fast charging, but Apple put old cheap chargers in the kit. If you want Quick Charge, buy adapters from Mac separately, and they are expensive.

6th place - Samsung Galaxy Note 9

Galaxy Note9 is a cool continuation of series 9. This "shovel" has become in demand, despite the high price. The device is in demand, equipped with top-end hardware from Exynos or Qualcomm, the best Amoled screen and a 2-module variable aperture camera, which allows you to take good pictures day or night.

In the DxOMark ranking, the smartphone shares 3rd place in the HTC U12+ (below is the link to the review), and is inferior in shooting to the iPhone XS, Huawei P20 Pro and Mate 20 Pro. The highlight of the flagship is the screen, since the best matrix in the world is installed here, which is nowhere to be found. Amoled is a Samsung technology, and the company does not sell the best developments to its competitors in the form of Apple or Huawei, but uses it in its devices.

• NFC and Samsung Pay.
• The quality of shooting photos and videos.
• Water resistant IP68.
• A large supply of memory - a disk of 128 or 512 GB + flash drive.
• A cool Bluetooth stylus that functions better than previous Note phones.
• Fast charging and powerful adapter included.
• The performance provided by the Exynos 9810 chip. For the US market, a modification was released on the Snapdragon 845.

• 10nm SD845 or Exynos 9810 processor. Huawei and Apple have already switched to 7nm chips.
• Not the best camera on the market.
• There are complaints about unoptimized software - there are friezes in the interface, although this will be resolved with the update.
• Auto brightness does not always work correctly.
• The corners of the body unpleasantly cut into the hand.
• Curled edges suggest random touches.

Modern technologies do not stand still, dynamically developing and improving. This also applies to the fundamentally new NFC technology, which literally flooded the entire world of mobile communications, providing a potential user with even more opportunities at minimal cost.

NFS in Samsung phones - what is it?

It is a technology universal solution for data exchange between devices. In fact, Samsung NFC is positioning itself as a contactless network of small radius, which works at a distance between mobile devices within 10 centimeters. Remarkably, despite the possibility of working with open data at such a distance, the network is as secure as possible. Information cannot be lost, just as data is not obtained by third parties. In fact, the Samsung NFC network is much more secure and complies high standards security than similar bluetooth, which has been relevant for a decade and a half.

All Galaxy smartphones with contactless technology

Currently, mobile device manufacturers are trying to implement this technology in their developments, providing an incredible level of quality of the units. Samsung NFC is not far behind, the models of which today are presented in the following names and modifications:

• Galaxy S8 is the flagship model that runs directly on operating system Android version 7.0. Supports simultaneous operation of two SIM cards, despite the fact that the mobile phone has one communication module. The screen size of the device is 5.8 inches, the resolution is within 2960x1440 pixels. The camera of the device has a resolution of 12 megapixels, autofocus is provided;
• The Galaxy A5 is a budget segment device that focuses solely on camera resolution. Like the older modification, it works on the Android operating system, version 6 and higher (depending on the one installed at the time of sale). Supports simultaneous operation of two SIM cards, between which you need to switch while using the phone. The screen has a diagonal of 5.2 inches, resolution is 1920x1080 pixels. The advantage of the unit is its camera, which has a resolution of 16 megapixels, with best quality autofocus shooting;
• Galaxy S7 - the technology was actively used by the manufacturer before, which resulted in the creation of a whole series of devices that support a fundamentally new standard for wireless data transmission. Smartphones run on the Android operating system, version 7.0, provide the ability to connect two SIM cards. The screen of the mobile phone is made standard for its segment of the market, it has a diagonal of 5.1 inches, the resolution is at the level of 2560x1440 pixels. You can select a high-quality camera, the resolution of which is 12 megapixels, and an autofocus option is also available.

Does Android Pay work on Samsung phones?

Quite problematic is the issue of compatibility of Android Pay payment functions, which are being actively implemented in new models of mobile phones. The problem is that each manufacturer tries to develop its own standards.

It is worth noting that Android, Apple and Samsung services are fundamentally similar in their structure, which allows them to be used in parallel with each other and ensure that all declared payment requirements are met. As gadget users note in reviews, sometimes there are malfunctions payment system from Android on devices of various modifications of the Galaxy S7, which is not surprising, taking into account the fact that the smartphone is actually the first from Samsung to use this technology in full.

The difference between Samsung Pay and Android Pay

What is Samsung Pay technology on Samsung mobile phones? The company not only tried to use the accepted NFC wireless communication standard in its work, but also made it possible to use it not only with individual terminals that support the possibility of making contactless payments for purchases. The solution actively uses proprietary technology, which has adopted the name MST (which translates as "magnetic safe transmission").

Thanks to the unique capabilities of the new technology, the user will be able to easily secure the payment for the purchase made by him on almost any type of terminal that provides for the use of a bank card as a payment instrument. To do this, you only need to have at your disposal a device compatible with the Samsung payment service that supports this "magnetic" technology. Through the use of the MCT, the creation of a magnetic field is ensured, according to its criteria, completely identical to that which has a magnetic stripe signal emanating from a bank card. As practice shows, even the sellers themselves in stores do not know about this possibility of mobile devices and are surprised that it really works in practice.

How to use NFC on Samsung

For the user, there is nothing easier than learning how to use NFC technology on Samsung. To ensure data transfer, it is only necessary to activate the software chip (provided that mobile phone has it in its design).

In the settings, it goes to the "Advanced" submenu, where the "NFC enable" item is provided, after which the option is activated. After that, Android Beam technology is automatically activated, if this does not happen, you can easily perform the operation in manual mode by clicking on the “Enable” item in the same settings menu. For full-fledged work, you will need to activate both technologies, it is important that none of the devices is blocked or turned off. When a vibration signal is received, this is the first sign that both devices have found each other and data transfer within the network can be started. Until the data exchange is completed, it is forbidden to separate your devices, this will lead to the fact that the information will be lost and you will have to do it all over again.

With technologyNFC, you can not only transfer data from one cell to another, but also pay for purchases(for example, buying groceries at the supermarket).

Decryption is simple - nearfieldcommunication, which, with a literal translation into Russian, means near-field communication or communication in the near space.

Initially, this technology was used for fast contactless payment. Now NFC replaces the plastic bank card and Bluetooth and combines them in one system, which is quite a practical invention to use. Want to make it easier to pay for purchases or transfer files? Let's figure out how to find out if there is NFC in your phone, tablet or laptop.

The history of the appearance of technology in the phone

It is believed that this is a relatively young development. Its appearance dates back to 2004: it was during this period that the three famous companies Nokia, Philipps and Sony organize the NFC Forum, and three years later they integrate the first NFC tags into a Nokia phone.

Smartphone models that support NFC

It should be noted that not all phones have support for this data transfer technology. It is known that NFC support is available for such devices as:

• Apple iPhone (starting with models 6S and 6S Plus);
• new Galaxy lineups from Samsung and smartphones from other manufacturers on the Android platform (starting from Android0).

Checking the device for NFC

Would you like to try the technology in practice, but do not know if this is possible on your device? Let's check.

To do this, carefully open the back cover of the smartphone or tablet, in a situation where it can move away without damage and inspect the gadget's battery.

With the presence of NFC development, you will see this abbreviation there. If the cover of the phone/tablet is not removable, then the corresponding icon or abbreviation will be located on the outside.

If for some reason you do not want or cannot remove the cover, you can make sure that this method of communication is available in the device settings.

Find the "Wireless networks" tab, then "More ..." and if NFC is available on the device, then there will definitely be a corresponding item.

How it looks, look at the photo above or in video instructions on How correctly checkNFC in the phone:

NFC activation

In case you found it on your device, you need to activate access to the technologyNFC. You can do this in the following way:

1. go to the "Settings" section and then "Wireless networks", "More ...", where earlier you could make sure that NFC is available;
2. confirm by clicking on the item "Allow data exchange when combined > device name > with another";
3. on an Android smartphone, Android Beam is immediately activated. If this does not happen, click on it and select "Yes" so as not to disrupt the system;

NFC can also be activated in the quick menu, in the same place where Wi-fi is turned on. This is done by touching the NFC tag.

See the video for more details:

What should I do if my device does not support NFC?

Don't worry if you don't find the built-in feature, there is a way to connect NFC to your device. But you can only do this if the panel cover on the back and the SIM card slot on your smartphone/tablet are removable. . Installing NFC in this case is not difficult.

Installing the NFC module

The optimal solution is to install a special module - an external communication device. It is compatible with almost all smartphones, easy to use and gives you access to NFC without buying a new phone.

Types of modules and methods of their implementation

Main types: chips, SIM cards, external devices, stickers. The last of them are of two types: passive - which do not allow data to be exchanged, and active - use Bluetooth and Wi-fi communication channels for transmission, which significantly increases energy consumption.

Such stickers are attached to the outer shell of the phone, which is also not very practical.

The most popular are the following:

• NFC SIM. Now available for purchase from most mobile operators. You can find out about the availability of such a SIM in the communication salon. You only need to install the finished card in your phone or tablet. This type of module is the most affordable and easy to install.
• NFC antenna. The second way, for which you will need to purchase an NFC antenna. You can do this in the communication salon. Next, the antenna is attached to the SIM card and inserted into the device.

As you have already seen, install the module quite simple and safe : You do not need to download additional applications or programs. However, these services do not completely replace the Android Pay app, but are just some of its many features.

How to use an NFC tag

An NFC tag is a miniature device in the form of a chip that can be attached almost anywhere: from your phone to being inserted under the skin!

We will not use such radical methods, but it is worth noting that contacts, settings, a URL and other data and commands can be placed on the chip. All gadgets can support the tag.

Data exchange via NFC

The technology can also be used to transfer files.

To transfer data, you need to do the following steps:

1. make sure that you have completed the activation of NFC and Android Beam;
2. unlock the device, exit the “sleep mode”;
3. check device discovery with each other;
4. connect;
5. transfer data between devices;
6. at the end, a specific sound signal will sound.

However, not all file types can be transferred this way. For example, attachments cannot be sent.

Advantages and disadvantages of NFC

The main advantages are:

• low price;
• small dimensions of the device;
• high transmission speed;
• support for almost all mobile devices X.

It is worth highlighting the cons:

• relatively small range;
• Not all devices are equipped with an NFC chip.

So, thanks to these notes, you have learned quick and simple ways checking your device for the possibility of transmitting information and interacting with other technical means using Near Field Communication. Following simple instructions of this article, you will also be able to find out for yourself whether the smartphone has this technology, you will be able to integrate NFC into your phone and transfer the necessary files at high speed.

All current Android smartphones have the top line of the screen literally crammed with all sorts of symbols. Many of them are understandable, familiar and even useful: the notification panel informs about new email messages, file downloads, availability and quality of telephone and WiFi networks, battery level, etc. However, sometimes a mysterious letter N appears there, causing some suspicious users to feel a little uneasy.

In this article, we will talk about the function that is indicated in Android devices by this very letter N, as well as how to disable it, and why you can do it right now.

• What does the N symbol stand for, and what is NFC?

On the Android notification bar, an intricately designed letter N appears as a sign that the smartphone (or tablet) has turned on the NFC module. NFC - Near Field Communication - is a technology by which two nearby mobile devices can exchange data (sorry for such a simplified definition).

You have probably heard about this technology and even seen it in action. In developed democracies, NFC is used everywhere: for example, in mobile payment systems (of the most famous in our country - Android Pay and Samsung Pay) - this is when it is possible directly from a smartphone, smart bracelets and other smart devices. In addition, through NFC you can also any other data from one smartphone to another.

• How to disable NFC in an Android smartphone (and remove the N icon from the notification bar)?

With this, everything is simple. Most likely in your Android you will find the option to disable NFC right in the quick settings menu. That is, we swipe across the screen from top to bottom, and in the drop-down menu, somewhere next to the Wi-Fi and Bluetooth symbols, we find an icon in the form of the same letter N, as in the notification panel, with a signature next to it and, if the function is active, tap on it to turn it off.

If you didn’t find the letter N in the quick settings of your smartphone, then open the usual settings, then click “ More… " In chapter " Wireless network "and in the subsection" File and data transfer » set the NFC option switch to the « Off “, after which the N symbol will disappear from the notification panel.

• Disable or not disable NFC?

Frankly speaking, at present there is practically no real benefit from NFC for the vast majority of Android users. Well, as we have already said, pictures or other files can be transferred from one smartphone to another. Contactless mobile payment systems are not yet so popular among the population, and there is such a suspicion that they will not be used for quite a long time. The aforementioned Android Pay and Samsung Pay, despite their very successful debut in the States, will not get to our region soon.

So, if you are not currently in an American store, then you can safely turn off the NFC function in your Android smartphone and save battery power in this way.
