RFDump is a software created by Lukas Grunwald and Christian Bottger for security auditing RFID tags. It is periodically updated to support emerging RFID standards, such as e-passport and Mifare encryption, that are currently found on many pay-as-you-go systems.

RFDump is a back-end GPL tool that interoperates directly with any RFID reader to make the contents stored on RFID tags accessible. The tool reads an RFID tag's 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. The cookie feature demonstrates how simple it is to abuse RFID technology, such as companies using it to spy on consumers. RFDump works with the ACG Multi-Tag Reader or similar card reader hardware.
