Wiegand Calculator
The Wiegand Calculator is a practical tool designed to decode and verify Wiegand credentials from a single input value. By entering a raw identifier, the calculator automatically converts and derives all commonly used Wiegand representations, making it easier to troubleshoot access control systems and validate credential data.
From the original input, the calculator generates the corresponding Wiegand hexadecimal value, full cryptographic digest, and truncated digest values often required by access control platforms and third-party integrations. These values are presented in both hexadecimal and decimal formats, allowing straightforward comparison across systems that store or transmit credential data differently.
In addition, the calculator extracts the facility code and card ID number, along with the full Wiegand binary and decimal representations, providing clear visibility into how a credential is structured at the bit level.
This makes the tool particularly useful when integrating ANPR (Automatic Number Plate Recognition) cameras and access control systems such as Paxton Net2, where external devices often output hashed, truncated, or transformed identifiers rather than native Wiegand values. The calculator helps bridge that gap by showing exactly how a value maps back to a valid Wiegand credential, reducing integration time and configuration errors.
By consolidating all of these conversions into a single workflow, the Wiegand Calculator serves as a reliable reference for engineers, installers, and system administrators working with Wiegand-based access control, ANPR, and third-party camera integrations.
