A tool for logging Wiegand data and also for testing devices contain a Wiegand Interface. A universal data logger that captures the raw binary data from a standard 5V Wiegand Interface. The device is capable of logging the credentials for access control systems or nearly any device that utilizes a Wiegand Interface such as RFID card , pin pads, magnetic stripe systems, and even some biometric . Wiegand Interfaces also do not have to be limited to just access control systems. 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. NOTE:1.Wiegand RFID reader is not included.2.Don' the module with battery only. Most of battery can't provide enough current for WiFi connection. Please try use 5V or 9V power adapter instead. The ESP-RFID-Tool also contains an unsupported experimental TX mode as well. In this mode you may mit the raw Binary of a card or even perform a couple of fuzzing tests, these include alternating bits on the D0 and D1 line and the device also has the ability to send bits on the D0 and D1 line at the same time. Although please note that the device has an output of 3V3 volts so it is not guaranteed to properly trigger all 5V Wiegand controllers. This mode is unsupported and was used for debugging the software while it was being written, TX mode is only being included as a bonus feature. If you decide to use TX mode then do so at your own risk. Colour:Green Material:PCB+Components Package Contents: 1 x RFID reader Only the above package content, other products are not included.
