Overview

Designed in cooperation with Grand Idea Studio, the Parallax Radio Frequency Identification (RFID) Read/Write Module USB provides a low-cost solution to read and write passive RFID transponder tags up to 4 inches away. The RFID R/W transponder tags provide a unique serial number and can store up to 116 bytes of user data, which can be password protected to allow only authorized access.

The RFID Read/Write Module can be used in a wide variety of hobbyist and commercial applications, including access control, user identification, robotics navigation, inventory tracking, payment systems, car immobilization, and manufacturing automation. This module's USB interface provides a direct connection to a computer.

Note that read/write distance will vary with tag type.
