HF RFID Demo Tag

The programmable RFID DemoTag can be used to emulate real RFID tags. The PCB consists of an antenna, the analogue front end and a programmable Atmel ATxmega256 microcontroller. Different interfaces to a computer allow to program additional functionality of the tag according the user's requirements. The HF 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 (semi-passive)
  • Atmel ATxmega256 microcontroller
  • PCB antenna and analogue front end
  • Supports RFID protocols ISO 14443A, ISO 14443A-4, ISO 18000-3, and ISO 18092 (NFC Forum Tag Type 4), with data rates up to 106 kbit/s.
  • Analogue front end: carrier frequency 13.56 MHz, ASK modulation, load modulation
  • Applications:
    • Evaluation of security holes in RFID systems
    • Blocker tag
    • Custom commands for additional functionality
    • Prototype system development for RFID systems with additional tag functionality
  • Interfaces: RS232 over USB plug, JTAG, ISP
  • Direct power supply by the USB board or battery
