Appendix G -Wiegand
Algorithms
The following decoding methods can be used for the terminals Wiegand interface:
32 bit
Algorithm 2:
Input: 1 (Even Parity bit) - 15 bits - 15 bits - 1 (Odd Parity bit)
Output - Facility code 5 bytes (15 bits)
Card Number 5 bytes (15 bits)
Algorithm 3:
Input: 1 (Even Parity bit) - 10 bits - 20 bits - 1 (Odd Parity bit)
Output - Card number 6 bytes (only 20 bits are decoded)
Algorithm 4:
Input: 1 (Even Parity bit) - 6 bits - 24 bits - 1 (Odd Parity bit)
Output - Card number 8 bytes (only 24 bits are decoded)
