4.4.4 NFC

The abbreviation NFC stands for "Near Field Communication." It is a feature that
allows users to connect to very close devices, capable of transferring data at a
maximum speed of no more than 474 kilobits per second. NFC differs in its ability to
exchange data within an extremely narrow range, not exceeding 4 centimeters
between the information exchange parties. This makes it highly secure for financial
transactions, as it cannot be wirelessly accessed remotely, unlike contactless credit
cards, electronic ticket cards, and virtual wallets .
