Wiegand Code Parser & Converter (26-bit and 34-bit)

This application is designed to easily convert Wiegand access control codes between different formats and verify their parity.

How to Use

1. Select Size: Choose between 26-Bit (standard format) or 34-Bit (extended format).

2. Select Input Mode:

   • Decimal/Hexadecimal/Binary: Use this mode to parse a complete Wiegand code.

   • FC/CN Pair: Use this mode to generate a full Wiegand code by entering the Facility Code (FC) and Card Number (CN) separately.

3. Enter Data: Input the code or the FC/CN pair into the relevant field(s).

4. Click "Parse & Convert."

Output Explained

The results section provides a complete breakdown of the code:

• Parity Check Status: Indicates if the entered full code is VALID or INVALID based on the Wiegand parity rules for the selected size. (For FC/CN Pair input, the generated code is always VALID.)

• Full Binary Code: Shows the 26 or 34 bits, color-coded for visual clarity:

  • Red: Parity Bits

  • Green: Facility Code (FC)

  • Blue: Card Number (CN)

• Extracted Values: Shows the Facility Code and Card Number in decimal format.

• Decimal/Hexadecimal Equivalents: Displays the final code in the alternate formats.
