Designed in cooperation with Grand Idea Studio, the 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. 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. Don’t forget to get a RFID tag too!
