Description
Frequency: 125KHz
Power supply: DC 5V (±5%)
Maximum effective distance: up to 50mm
Includes external antenna
The Seeedstudio 125KHz RFID Module - UART is designed for reading code from a 125KHz compatible card with read-only tags and read/write card. It can be applied in office security, home security, personal identification, access control, anti-forgery, interactive toy and production control systems, etc. This Seeedstudio 125KHz RFID Module - UART supports external antenna which is included. The maximum effective distance is up to 150mm.
Features:
Supports external antenna
Maximum effective distance up to 150mm
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: The module will notify whenever 125khz tag approaches, tag serial number will be send via TX pin. This is an easy way for a RFID module on MCU projects or PC connection via UartSB.
This is a RDM360 (not to be confused with the lower quality, multi-read RDM3600). Integrates easily with Arduino using a single I/O (2 I/O if you want to use interrupts). Antenna is small but provides detection distance of about 2-3cm with standard tags.

Great Little No-Frills RFID
I have purchased 15 of these so far and love them. You have to keep in mind that the range is about 1 cm so they are best if the card or fob is swiped very close to the antenna. I use the mated fobs and cards and I never found a repeated code,

speedy delivery
Speedy delivery and product works great. Unlike other RFID solutions, this works straight from the box with no software setup required.
