OFFFFFFFFFFFFFFFFCCCCCCCCCCCCCCCCMME
Consists of 36 bits of binary code. The 1
st
bit is the odd parity bit of the 2
nd
to 18
th
bits, while the 36 th bit is the even parity bit of the 19 th to 35 th bits. 2 nd to 17 th bits
are the device codes. The 18 th to 33 rd bits are the card numbers, and the 34 th to
35 th bits are the manufacturer codes.
