Turn your Raspberry Pi into an intelligent data collector using the 125KHz RFID Reader from CognIoT. The Reader offers one of the best OOB (out of box) experiences for Pi based RFID readers. By using the UART of the Pi for communication and the built in intelligence of the Reader the user is able to operate the Reader without the need for libraries to be downloaded and compiled onto the Pi. Example software shows how to setup the 125KHz RFID Reader and how to monitor the RFID tags. The uses are endless - what will you design with the 125KHz RFID Reader?

The RFID reader is intelligent making your life simpler. The Pi sends commands to the reader over the UART to perform operations like Read tag serial number, Read/Write blocks and pages and Mode select for Hitag 1/S, Hitag 2, EM400X/4102 or MCRF2001/12.

A green LED indicates a read of a valid tag/card. Antenna problems (broken, shorted or even badly tuned) are detected and indicated by the red LED output “flashing” continuously. Correct operation can be confirmed without anything running on the Pi. This product aims to make it easier for you to design with. The Pi RFID Reader supports Hitag 1, Hitag S256/S2048 (RTF/Plain Memory mode), Hitag 2 (Password mode), EM400X/4102 and MCRF200/123 passive RFID transponder types. The solution only needs a 770 µH antenna coil connected to be a fully featured read/write system.
