
Bit 1 is an even parity bit for the first 12 bits (bit 2 to bit 13).

Bit 26 is an odd parity bit for the last 12 bits (bit 14 to bit 25).

Bit 2 to bit 9 is site code in binary format, if the site code ID is less than 8 digits, 0
will be added before the ID until it is 8-digit number.

Bit 10 to bit 25 is site code in binary format, if the card ID is less than 8 digits, 0 will
be added before the ID until it is 16-digit number.
Example:
Here we take card number: 12345 011 as example.
The coding process are show as below.
Steps:
Split the card number as the card ID (12345) and site code (011).
1. Convert 12345 to binary format, as: 0011000000111001.
2. Convert 011 to binary format, as: 00001011.
3. Site data and card data as: 0000 1011 0011 0000 0011 1001.
4. Bit 1 is an even parity bit for the first 12 bits (bit 2 to bit 13), as 1.
5. Bit 26 is an odd parity bit for the last 12 bits (bit 14 to bit 25), as 1.
6. According to the converting mode(Even parity bit + site data + card data + odd
parity bit), you can get a binary code as:
1 00001011 0011000000111001 1.
3.1.2 Configuration
