Badge Formats in 40-Bit and 55-Bit Wiegand Protocol
4002 - 40-Bit Wiegand Format
The 40 bits of transmission consist of two parity bits and 38 code bits. The first bit transmitted is the first
parity bit, P1; it is even parity calculated over the first 20 bits. The last bit transmitted is the second parity
bit, P2; it is odd parity calculated over the total 40 bits.
Code format:
F = Facility – 0 Digits
B = Badge Number (99.999.999.999 possible) 12 digits
This format was created to enable identical badge identification numbers to be produced in either
S-F/2F or Wiegand mode. These numbers are derived from the 40-bit binary code in the proximity
chip. The badge number is comprised of the 38 least significant bits. The most significant bit is set at
0.
5502 - 55-Bit Wiegand Format
The 55 bits of transmission consist of two parity bits and 53 code bits. The first bit transmitted is the first
parity bit, P1; it is even parity calculated over the first 27 bits. The last bit transmitted is the second parity
bit, P2; it is odd parity calculated over the total 55 bits.
Code format:
F = Facility – 0 digits
B = Badge Number – 16 digits
P = Parity Bit
