ESP RFID Tool

Description

Intended use cases

Security researchers performing red team assessments.
Capturing card values to later be cloned.
Replaying raw binary captures.*(see note below)
Fuzzing access control systems.*(see note below)
To create a standalone device for testing badges and or card readers without the need for a Wiegand Controller.
Add a battery and a card reader to make the unit portable.
Add a benchtop power supply to use for testing hardware.
Installers troubleshooting issues with a card reader or the data lines out in the field or back in the office.
Hobbyist experimenting with various systems that utilize a Wiegand Interface.
Simulating an access control system using multiple units of ESP-RFID-Tool.

ESP RFID Tool is a WiFi enabled tap for the Wiegand protocol, which is the most widespread protocol for proximity card reader systems. ESP RFID Tool can be installed in a reader to passively sniff and log Wiegand data.

The main target group for this device is 26-37bit HID cards. For known card types both the binary and hexidecimal data is displayed directly in the log file for easy badge identification and also in case a clone of a card may be needed. For unknown card types only the raw binary data is shown. The device was made primarily for data logging and while there is a transmit mode, it is an experimental feature. Access to the log files and various settings is provided via a web based interface. The device has WiFi capabilities and can be set up to spawn its own access point or set to connect to an existing network.
