RFDump is a backend GPL tool to directly interoperate with any RFID ISO-Reader to make the contents stored on RFID tags accessible. First presented at Black Hat 2004.

RFDump is a tool to detect RFID tags and show their meta information: Tag ID, tag type, manufacturer etc. The user data of a tag can be displayed and modified using either a Hex or an ASCII editor. RFDump works with the ACG Multi-Tag Reader or similar card reader hardware.

This makes the following types of audits possible:

- Test robustness of data-structures on the reader and the backend-application

- Proof-of-concept manipulations of RFID tag contents

- Clone / copy & paste User-Data stored on RFID tags

- Audit tag-security features

RFDump is available in different versions:

- As Gtk application for Linux/Unix with a GUI

- As rudimentary Perl script for Linux (PC or PDA) with a console-based interface

RFDump features (Gtk Application): Runs on Linux, Windows; supports ACGs PCMCIA/CF Multi-Tag Readers; decodes the tag type, tag ID and manufacturer; displays tag memory in Hex and ASCII encoding; allows to write memory using Hex or ASCII editor.

Recommended Hardware:

- Linux/Windows PC or HP iPAQ PDA with Linux

- ACG Multi-Tag Reader, in a CF-Flash Socket or PCMCIA Adapter

- 13.56 MHz Tags for testing
