What is a Payment Account Reference (PAR) and why does it matter to merchants?
PAR is an alphanumeric reference point that enables a business to track a consumer and their payment account across the various payment methods they use. For example, a consumer may have 3 credit cards in their wallet, each of which would generate a different token if used in a tokenized environment. PAR links these cards to a single payment account and broadens the idea of tracking a consumer’s activity across payment methods beyond the scope of a single merchant.
