125 kHz RFID Reader Module with Serial Output

RFID reader modules are electronic devices that detect the presence of tags in the environment and retrieve the information stored in them. This RFID module 125 kHz is ideal for low-cost projects such as office/home security, personal identification, access control, interactive tools, production control systems, and more. The module transmits data via the UART protocol, making data transfer through this interface relatively easy.

RFID readers are generally divided into four categories:

• 125 kHz or LF (Low Frequency), including RO and RW cards
• 13.56 MHz or HF (High Frequency), including Mifare, Desfire, NFC cards, etc.
• UHF frequency band (long-range passive), including EPC GEN2 cards and tags
• Long-range active, including tags and cards with batteries

This RFID reader module operates at a frequency of 125 kHz and features a serial output, making it highly suitable for various applications.

Applications of the 125 kHz Reader

1. Access control
2. Asset management and tracking
3. Document tracking
4. Smart farming systems or animal tracking
