RFID (radio-frequency identification) is the wireless non-contact use of radio-frequency electromagnetic fields, for the purposes of identifying and tracking tags attached to objects. This is the ID-12LA, a very simple to use RFID reader module from ID Innovations. With a built in antenna, the only holdup is the 2mm pin spacing (breakout board available below). Power the module, hold up a 125khz card, and get a serial string output containing the unique ID of the card.

The new ID-12LA is essentially the same as the ID-12, but has a lower voltage input. 

Features:

• 2.8 - 5V supply
• 125kHz read frequency
• EM4001 64-bit RFID tag compatible
• 9600bps TTL and RS232 output
• Magnetic stripe emulation output
• 120mm read range

Dimensions: 25x26mm
