Description: 64 bits binary, sent as 8 bytes hexadecimal. Indicates use of ISO 8583 Fields 1 – 64.
Example:
The following fields are present in an incoming message:
- 3, 4, 7, 11, 12, 14, 22, 26, 28, 29, 32, 35, 37, 41, 42, 43, 48, 49, 55, 63, 64
These fields are represented as the value ‘1’ in a string of 64 characters; fields absent are represented as ‘0’:
- 0011000000110100000001000101100100101000111000011000001000000011
This string is converted to binary:
- 0011 0000 0011 0100 0000 0100 0101 1001 0010 1000 1110 0001 1000 0010 0000 0011
The binary is converted to 8 bytes hexadecimal:
- 30 34 04 59 28 E1 82 03
