NFC technology

Near Field Communication (NFC) is a technology that allows two devices to communicate wirelessly when they are close to each other. It uses radio waves to transmit data over a very short distance, typically a few centimeters. NFC is often used for contactless payments, but it can also be used for other applications such as pairing Bluetooth devices, reading smart posters, and access control. NFC operates on the MHz frequency and the most common communication standard are ISO/IEC 14443 for proximity cards and ISO/IEC 18092 for near field communications. It is mainly used for secure and ease of use proximity transactions and more common in mobile payments and access control. An NFC chip is typically embedded in a device such as a smartphone, tablet, or smartwatch and can be used to make payments by holding the device close to a point-of-sale terminal or access control point. As it's short-range and low-power it's also often used for peer
