Several levels blacklisting and whitelisting are available:
- Geographic regions-MAP numbers
- Phone Numbers
- IP Addresses
Blacklists allow unconditional transaction denial based on the above-mentioned criteria.
On the same criteria basis, blocking allows to avoid potential blacklists and other acceptance rules.
For example: if a whitelisted card, an IP address, an e-mail, or a phone number is presented to the rules engine, only unconditional rules will be executed.
