    Designed in cooperation with Grand Idea Studio, the Parallax Radio Frequency Identification (RFID) Reader Module is the first low-cost solution to read passive RFID transponder tags. The RFID Reader Module can be used in a wide variety of hobbyist and commercial applications, including access control, automatic identification, robotics, navigation, inventory tracking, payment systems, and car immobilization.

    This reader is compatible with EM4102 RFID tags (125 kHz).  The read range varies between 0.5" and 6" depending on the size of the tag's antenna.

    This device can be connected to a PC serial port using a MAX232 line driver. The circuit isn't supported by Parallax, but it's possible to make this connection with a few dollars of parts.

    Features:

    • Fully-integrated, low-cost method of reading passive RFID transponder tags
    • 2400 baud TTL serial interface (output only) to PC, BASIC Stamp module and other processors
    • Requires single +5VDC supply
    • Bi-color LED for visual indication of activity
    • 0.1" pin spacing for easy prototyping and integration
