NFC technology
Modern ATMs and terminals are becoming more convenient with the introduction of the latest technologies. Near Field Communication allows you to exchange information with the bank and other organizations without physical contact. For this, ATMs and terminals use wireless NFC technology.
The key element of this wireless technology is devices for reading information from compatible mobile devices or bank cards - NFC readers. NFC-compatible devices can safely exchange information at a distance of just a few centimeters, Bluetooth and Wi-Fi have a longer communication range. To make a transaction, you need to bring a compatible mobile device or credit card close to a certain place on the ATM or terminal.
Wireless NFC technology does not require a connection to Bluetooth, the Internet, Wi-Fi, and even more so a wired connection. Unlike Bluetooth, NFC in a phone does not require searching for and pairing devices. When paying contactlessly, the NFC module in the phone generates an electromagnetic field. The terminal is exposed to this field and creates an induction current, which is used to exchange information. Briefly, NFC works as follows. First, the devices must be NFC-compatible, and one of them must have an active radio module. The stages of NFC interaction are: initialization, establishing a connection, data transfer, payment processing (a transaction takes place in the payment system and funds are withdrawn from the account), confirmation and completion. Payment data both between the smartphone and the ATM/terminal, and between the ATM/terminal and the bank (Wi-Fi, Bluetooth LE, wired or satellite Internet, mobile cellular communication are used here) are transferred instantly.

Wireless NFC technology is suitable for interaction with an ATM, payment at a point of sale via a POS terminal, file transfer, reading information from electronic tags and using electronic tickets and similar operations. Apple Pay and Google Pay work using NFC technology.
