RFID reader modules operating in the HF (High Frequency) range are commonly used for various applications such as access control, inventory management, and tracking of assets or products. Here's a brief overview of HF RFID reader modules:
1. Operating Frequency:
HF RFID operates at frequencies between
13.56 MHz, which is the standard frequency for most HF RFID systems. This
frequency range offers a good balance between read range and interference
resistance.
2. Communication Interface:
HF RFID reader modules typically support
various communication interfaces such as TCP/IP、USB、BLE、WiFi、I2C、UART、Wiegand、RS-232、RS-485. These interfaces allow the reader module to
communicate with external devices such as computers, microcontrollers, or network
servers.
3. Features:
ISO 14443A/B, ISO 15693 protocol, ISO
14443A/B is the principle of electromagnetic induction near-field coupling, the
distance is close, but there are many encryption protocols, mainly used for
identity recognition; ISO 15693 protocol is the principle of electromagnetic
induction near-far field coupling, the distance is relatively Far away, mainly
disturbed by metal.
4. Antenna Options:
HF RFID reader modules may come with
On-board Antenna or require an External antenna connectivity for operation. The
choice of antenna depends on factors such as desired read range, application
requirements, and form factor constraints.
5. Applications:
HF RFID reader modules find applications in various industries, including retail, access control system, healthcare, logistics, transportation, electronic wallet, digital signature. They are used for tasks such as inventory management, asset tracking, contactless payment systems, and access control.
