RFID Tag Emulators for HF and UHF Frequency Range

Introduction

The programmable IAIK RFID DemoTags can be used to emulate real RFID tags. The PCB consists of an 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 HF and the UHF DemoTags are perfect tools 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.

HF DemoTag

UHF DemoTag

Features 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) Analogue front end: tuned for carrier frequency of 868 MHz 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, JTAG, ISP

We offer our research results for secure RFID technology. Our webstore provides more specific information. You can order the RFID DemoTags which are fully programmable to test RFID systems against attacks with cloned tags. The PCB provides the functionality of a programmable RFID tag with antenna and analog front end for many different protocols in the HF and UHF frequency range.
