HF RFID module is a module that works in the frequency band of 13.56MHz. HF is divided into different protocols such as ISO/IEC 14443A, ISO/IEC 14443B, and ISO/IEC 15693 . Correspondingly, there will be HF RFID tags working in different protocols.

ISO/IEC14443 protocol is divided into two types: TypeA & TypeB, both operating at 13.56 MHz (RFID HF). They are close-reading protocols. Label read-write distance is 0~10cm. The main difference between A and B lies in their modulation, coding schemes, and anti-collision methods.

 

ISO/IEC 15693 is a long-distance reading protocol and also a popular HF (13.56 MHz) standard for High RFIDs widely used for non-contact smart payment and credit cards.

 

It is compatible with ISO 18000-3 and allows long-distance communication. The maximum reading distance is 100mm, and the application is more flexible. It widely used in production automation, medical management, jewelry inventory, asset management, parking management and product anti-counterfeiting, access control, asset management, logistics & supply chain, library management, etc.
