Wiegand Format Definition
Wiegand26 ECCCCCCCCCCCCCCCCCCCCCCCCO
Consists of 26 bits of binary code. The 1
st bit is the even parity bit of the
2
nd
to 13
th
bits, while the 26
th
bit is the odd parity bit of the 14
th
to 25
th
bits. The 2 nd to 25 th bits are the card number.
Wiegand26a ESSSSSSSSCCCCCCCCCCCCCCCCO
Consists of 26 bits of binary code. The 1
st
bit is the even parity bit of the
2 nd to 13 th bits, while the 26 th bit is the odd parity bit of the 14 th to 25 th
bits. The 2 nd to 9 th bits are the site code, while the 10 th to 25 th bits are the
card number.
Wiegand34 ECCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCO
Consists of 34 bits of binary code. The 1
st bit is the even parity bit of the
2
nd
to 17
th
bits, while the 34
th
bit is the odd parity bit of the 18
th
to 33
rd
bits. The 2 nd to 25 th bits are the card number.
Wiegand34a ESSSSSSSSCCCCCCCCCCCCCCCCCCCCCCCCO
Consists of 34 bits of binary code. The 1
st
bit is the even parity bit of the
