Serial RFID Card Reader

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.

There are a variety of transponder tags that come in different packages. Each tag has a specific range that is within 10% of the given distance for each type of tag. The reason for the 10% is due to environmental conditions and RFID modules.

Features:
  • Low-cost method for reading passive RFID EM4100 family transponder tags
  • 2400 baud serial interface
  • Enable input allows module to be enabled/disabled by software
  • Bi-color LED for visual indication of status

    Compatible tags:
  • 54x85mm Rectangle Tag ISO Card: 6.3cm (2.5") ±10%
  • 50mm Round Tag World Tag: 6.8cm (2.7") ±10%

    Key Specifications:

    Note: No tags are included with the RFID Reader Module. 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 or by using the USB version of the reader. There is an outline of connections on the forums.
