Consists of 34 bits of binary code. The 1st bit is the even parity bit
of the 2nd to 17th bits, while the 34th bit is the odd parity bit of
the 18th to 33rd bits. The 2nd to 9th bits are the site codes, while
the 10th to 25th bits are the card numbers.
OFFFFFFFFFFFFFFFFCCCCCCCCCCCCCCCCMME
Consists of 36 bits of binary code. The 1st bit is the odd parity bit
of the 2nd to 18th bits, while the 36th bit is the even parity bit of
the 19th to 35th bits. The 2nd to 17th bits are the device codes.
The 18th to 33rd bits are the card numbers, and the 34th to 35th
bits are the manufacturer codes.

Consists of 36 bits of binary code. The 1st bit is the even parity bit
of the 2nd to 18th bits, while the 36th bit is the odd parity bit of
the 19th to 35th bits. The 2nd to 19th bits are the device codes,
and the 20th to 35th bits are the card numbers.

Consists of 37 bits of binary code. The 1st bit is the odd parity bit
of the 2nd to 18th bits, while the 37th bit is the even parity bit of
the 19th to 36th bits. The 2nd to 4th bits are the manufacturer
codes. The 5th to 16th bits are the site codes, and the 21st to 36th
bits are the card numbers.
