HF (13.56MHz) is typically used for short-range, secure applications like payments or access control. UHF (860-960MHz) offers longer read ranges, making it ideal for inventory tracking and logistics.

Integrated modules for contactless identification and data capture
What are RFID Reader Modules components?
RFID reader modules are self-contained subsystems that handle the RF signal processing, modulation, and protocol decoding required to communicate with transponders. Select based on operating frequency (LF, HF, UHF), read range, and host interface (UART, SPI, RS232/485).
How to Choose RFID Reader Modules Components
Selecting the right module requires balancing physical constraints with protocol compatibility.
Frequency Band
Match the module to your tag type: LF (125kHz) for short range, HF (13.56MHz) for NFC/proximity, or UHF (860-960MHz) for long-range logistics.
Host Interface
Ensure the module's output (UART, SPI, I2C, or industrial fieldbus) aligns with your MCU or PLC architecture.
Read Range & Power
Assess the antenna gain and power budget; higher read ranges often require higher peak current and larger antenna footprints.
Environmental Rating
For industrial use, verify IP ratings and vibration resistance, especially for fixed-mount reader heads.
Protocol Support
Confirm support for ISO/IEC standards (e.g., 14443, 15693) to ensure interoperability with your specific tag inventory.
