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.
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
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.

Can it write? Can it read anything beside the ID?
Is there anyway to improve the distance in which it would pick up the RFID tags I'm using? Currently the tags have to be within 10-15mm of the actual antenna to set it off. Let me know. Thank you.
