At first glance, it may seem that numerous wireless intenses today are already covering all possible popular tasks and scenarios, so another option is simply not needed. However, if you look at the development of modern technologies, you can see that more and more attention is paid to energy consumption issues, especially when it comes to mobile devices.

In particular version 4.0 of the famous Bluetooth protocol family is just focused on reducing the cost of battery charge. The second point that is worth mentioning is that not every task requires a large range. It happens even the opposite. I want to clearly limit the distance between the interacting devices.

In addition to an obvious decrease in consumption, this also affects safety. And about the volumes of the transmitted data, you can also make a similar remark. So the idea of ​​a wireless integration, which works at short distances and is characterized by low energy consumption, has the right to exist.

For the starting point of reference in the history of NFC development, you can accept 2004 when Nokia, Philips and Sony announced the creation of the NFC forum in order to develop and standardize the interaction interaction interaction interaction based on touching.

However, the first versions of the specifications were created a little earlier. Perhaps, by modern standards, the technology can be considered very young (if you do not take into account the history of RFID), but it is already often found in real products and services. In particular, at the end of February, Mobile World Congress 2021, many stands and demonstrations were devoted to this topic.

Such a sign can be found on devices with NFC technology

The formal characteristics of the integse are as follows: work at a distance of several centimeters, the maximum rate of information exchange is about 400 kbps, the full.duplex data exchange is maintained, the operating frequency is 13.56 MHz, the connection time does not exceed 0.1 s, the operating mode is a point. a point. a point. It can be seen that these parameters radically distinguish NFC from other popular wireless intenses.

If we talk about devices, then in addition to active controllers in NFC there are passive options (they are usually called marks) that receive food wirelessly from the active controller. One example is modern maps for traveling by city transport.

One of the simplest options for passive NFC tags

The compact size of the controller and its low consumption allows you to implement NFC even in small structures such as SIM cards or Microsd memory card. However, for full work, it is necessary to use a special antenna. In the phones, it is usually on the back of the battery cover or is built into the rear panel if the device does not involve a removable battery.

NFC antenna is often placed on the back cover of the smartphone

A small range of action can adversely affect when using tablets. finding the right place for “applying” may not be as simple as we would like. To solve this problem, some manufacturers mark the location of the antenna with a special sign.

From the point of view of security, the developers did not realize the elements of protection against interception and relay attack. This of course makes it difficult to implement safe solutions, since it requires protection from the protection at a higher level. Note that in fact, such a well.known protocol as TCP/IP behaves similarly.

Perhaps the most important thing is that you need to know about NFC today is that the integration itself does not give any real practical scenarios of use or solutions. In contrast, for example, Bluetooth, whose profiles are clearly described how to transfer the file, how to connect a headset or provide network access, NFC is only a database, and direct work scenarios are provided by additional software that works through it.

It is interesting that any programs installed on the smartphone or tablet can register in the operating system as processors of events associated with NFC, and then, with an external “call”, you will see the standard menu “How you want this action?””.

The NFC forum is trying to help with this uncertainty, offering to standardize protocols for certain scenarios (in particular NDEF for storing short messages on the marks and SNEP (Simple NDEF Exchange Protocol) for the exchange of information between devices), however, the practical determination of the compatibility of specific devices is usually complicated by the lack of detailed information From the manufacturer and diagnostic tools.

Android Beam

The Android Beam function uses the NFC chip to transmit data from one device to another. For example, to exchange Internet links, contacts, photos or videos, just bring your phone to a device with the same NFC technology.

The technology is somewhat reminiscent of Bluetooth, but it acts at a distance of only a few cm.

How to turn it on? We go to the settings. connection. NFC and payment. Android Beam. Move the switch to the position of.

Contactly payments

To make contactless payments from the phone on your device should be a chip NFC. To set up payments, we go to the settings. connection. NFC and payment. contactless payments.

We are offered to choose a payment service used by default: Samsung Pay or Google Pay. For Samsung phones, I recommend choosing the first option, for phones of other brands. use Google payments (Google Pay).

NFC in Samsung phones. what is it?

The issue of compatibility of payment functions Android Pay, which are actively introduced into new models of mobile phones, is quite problematic. The problems are that each manufacturer tries to develop their own standards.

There is nothing easier for the user than to learn how to use NFC technology on samsung. To ensure data transmission, you just need to activate the software chip (provided that the mobile phone has it in its design).

To use Android Pey, your smartphone needs to have support for NFC technology and, in addition, it should work on the Android 4 operating system.4 “or above.

Smart TV Samsung functions and characteristics

Samsung Smart TV is not just a TV, but an advanced multifunctional platform. It includes advanced possibilities for viewing various content. This system resembles a traditional computer or smartphone much more.

Here you can easily use social networks, watch videos and install various applications. It is these functions that make Smart technologies so popular.

The main functions of Smart TV include:

How to connect

SMART TV Samsung configuration is impossible without Internet connection. This is the only way to use all the functions of the TV. Without the Internet, buying a device is inappropriate. Consider the methods for connecting to a network of televisions of different series.

Wending connection LAN

This method is to directly connect the TV to the external modem. For this, a standard Ethernet Cabble is used. Most often, this method is used for TVs of 5 episodes that do not use wireless modules.

Connection can be carried out not only through the modem, but also directly through the network outlet. It is better to learn in advance about the possibility of such a connection, as it depends on specific tv settings.

To implement the connection to the dynamic network, you need to do the following:

Upon completion of the check, the network will be configured. This approach is implemented in devices with support for the DHCP system.

Wi-Fi wireless connection

The TV must be connected to a wireless IP device (modem or router). If DHCP support is present, then you can use this protocol and automatically configure the connection.

It is important to choose a free channel for the TV, since using two devices of one channel will lead to interruptions and interference.

Rectangular usb rectangular adapters are widely used, which allow you to easily organize an access point. This adapter is connected at one end to the port of the Samsung wireless local network, and to others to the USB port.

You can also use an extension cable. It connects to the USB port and to the adapter of the Samsung wireless local network. In this case, the adapter itself can be fixed on the rear wall of the TV.

As a password, a combination of letters and numbers is used.

It is recommended to use letters of different register. The password is entered with the initial tuning of the wireless network, and then each new connected device should use the network with this password.

It is worth noting. That if the connection speed is below 10 Mbps, then problems may occur with automatic setting. In this case, manual input of parameters may be required.

After that, the connection will be configured and you can start using the functionality of the device.

Connection using WPS

The connection of devices is widely used through WPS function. In order to implement such a connection, you need to perform the following:

Thus, one button sends all the information to TV and implements automatic tuning a wireless network. Upon completion of the setup, a network check screen will appear. This means that the connection took place.

Using Plug Access technology

If the modem or router supports the Plug Access function, then you can use it to configure wireless connection. This is necessary:

The appearance of the network check screen indicates the successful completion of the setting.

If the settings of the router change during the use of devices, then you must repeat the procedure to update data.
