Basic Concepts of 13.56 MHz NFC Technology
NFC Technology Overview
NFC (Near Field Communication) is a short-range wireless communication technology based on wireless RFID (Radio Frequency Identification). Its core principle is to achieve bidirectional data transmission through electromagnetic induction or magnetic coupling between two devices. The effective range of NFC communication is usually only a few centimeters. This proximity enhances data security and minimizes interference. It is widely used in mobile payments, identity verification, and smart device connections.
The Uniqueness of the 13.56 MHz Frequency Band
Standard Operating Frequency: NFC technology operates at the internationally standardized frequency of 13.56 MHz. This common frequency enables NFC devices, such as smart cards, readers, and smartphones, to communicate within the NFC ecosystem. However, actual compatibility depends on factors such as supported protocols, card types, data formats, and application requirements.
