What is a blacklist?
A blacklist is a list of data such as names or bank details of customers that have caused problems in the past. These are automatically detected and rejected when processing a transaction. For example, if a merchant has had bad experiences with a particular credit card, blacklisting it automatically prevents its use from then on. Merchants can use blacklists to protect themselves from payment defaults and attempted fraud.
What is the difference between this and a whitelist?
A whitelist is the opposite of a blacklist. Trustworthy customers (such as regular customers) who have been placed on a whitelist enjoy special benefits. For example, merchants can offer them options that are not available to other customers, such as making purchases on account or paying in installments.
