One of the coolest part of IoT project must be the identification technology, 125Khz RFID module – UART is the most popular RFID module that produced by Seeed, By connecting this RFID module to Arduino or Raspberry Pi, you are able to build projects that can be used in office/home security, personal identification, access control, anti-forgery, interactive toy and production control systems etc.
Features
Support external antenna
Maximum effective distance up to 50mm
Less than 100ms decoding time
UART TTL interface
Support EM4100 compatible read only or read/write tags
Built-in external bi-color LED and buzzer driver
Small outline design
Note:
Module will notify whenever 125khz tag approaches, tag serial number will be send via TX pin. Easy way for a RFID module on MCU projects or PC connnection via UartSB.

Hi , it can not use for writing data to cards/tags.You can refer to the module "13.56Mhz RFID module" , just it is in the different frequency card.

The reading distance depends on many factors i.e tag size, antenna size, tag and antenna orientation, etc. In the current case you can use external booster circuit to improve reading distance.

Would it be possible to send me the antenna portion of the schematic? It appears to be just an opamp with some discretes, maybe I can modify it to suit my antennas.

Hey alanv73 I can confirm that this works with implantable chips, I have one in my hand and one in my dog, both work with this reader. however I know there are some proprietary chips out there such as the avid brand which i havent tested, so your mileage may vary
