If a prefix gives several hits in the Prefix table, the validation rules should be evaluated. Use the first approved hit. This allows multiple prefix records with prefix ‘4’ (VISA) to be defined with different validation methods (online, offline, online & offline) and the validation rules shall be checked to see with prefix record to apply.
If a card validation rule uses more commands, separate the command with a star (*)
Example
S09:14:15*B24:25=01;10;11;21;22*A4=0*M0:4
