In a database that is associated with the retailer POS system, inventory is flagged as being FSA-eligible and a retailer POS system is programmed to support FSA debit card auto-adjudication, i.e., the retailer POS system is IIAS certified. The FSA-eligible information that is stored in the retailer POS database is also used to flag for a customer FSA-eligible items presented to the user online, e.g., in an online catalog. When an FSA-eligible item is purchased on-line or at a retailer POS, the FSA debit card information is captured and the purchase transaction is processed by the retailer POS system so the customer has easy access to FSA purchases via either channel.
