The programmable RFID DemoTag can be used to evaluate RFID systems. The PCB consists of an UHF antenna, the analogue front end and a programmable Atmel ATMega128 microcontroller. Different interfaces to a computer allow to program additional functionality of the tag according the user's requirements. The UHF DemoTag is a perfect tool to evaluate existing RFID applications or to build prototype systems that rely on tags with additional functionality which can be access via defined custom commands).


  • Programmable, battery-powered RFID tag
  • Atmel ATMega128 microcontroller
  • PCB antenna and analogue front end
  • Supports RFID protocol ISO 18000-6C/EPC Gen2 (EPCglobal UHF Class 1 Generation 2), with Tari > 12us and Tpri > 10us (BLF < 100kHz).
  • Analogue front end: tuned for carrier frequency of 868 MHz (reduced read range for 900-920MHz)
  • Applications:
    • Evaluation of security holes in RFID systems
    • Blocker tag
    • Custom commands for additional functionality
    • Reader development for systems with additional tag functionality
  • Interfaces: RS232 over USB plug, JTAG, ISP
  • Direct power supply by the USB board or AC power supply adapter (220V/50HZ to 12V)
