RFID Card Reader Board, 125kHz EM4100 Compatible, 4-pin Serial US$49.99

28140
RFID Card Reader Board, 125kHz EM4100 Compatible, 4-pin Serial


This RFID Reader Module, designed by Grand Idea Studio and Parallax, is a low-cost solution for reading 125 kHz passive (read-only) 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.

The Parallax RFID Card Reader Serial version easily interfaces to any host microcontroller using only four connections: VCC, /ENABLE, SOUT, and GND. When the RFID Card Reader is active and a valid RFID transponder tag is placed within range of the activated reader, the tag's unique ID will be transmitted as a 12-byte printable ASCII string serially to the host (first byte is Line Feed; last byte is Carriage Return).

Serial RFID Card Reader Features

  • Reads 125 kHz passive RFID transponder tags in the EM4100 family
  • Power requirements: 4.5V to 5.5V DC
  • 2400-baud serial interface (8N1)
  • Enable Input allows module to be enabled/disabled by software
  • Bi-color LED for visual indication of status
  • Dimensions: 2.45 3.25 0.22 inches (62.2 82.5 5.57 mm)
  • Operating temperature range: -40 to +185 F (-40 to +85 C)

This RFID Card Reader does not come with any tags. Compatible tags can be ordered from the Optional Recommended Products list below.

For easy connection to a PC, you might prefer the USB version of this reader.
