A flexible spending account (FSA), Flex for short, is one of several types of tax-advantaged finance accounts that can be established through a company's cafeteria plan.  In more and more cases account holders are being issued debit cards which can be used against the available funds in that account.  This, in turn, has produced a growing number of potential customers, cards in hand, all searching for a pharmacy able to process FSA debit cards.

As of 2009 the use and processing of FSA debit cards falls under strict IRS regulations, requiring pharmacy retailers who wish to accept Flex cards to operate an IIAS (inventory information approval system) compliant point of sale system. Prism version 7.6 FD enables pharmacies to meet this requirement.

Prism version 7.6 FD showcases an IIAS compliant Point of Sale system capable of real-time, auto-substantiation for eligible items purchased with a Flex payment card. By integrating both the SIGIS-established list of qualified FSA items and the Heartland-established list of recognized FSA debit cards, Prism’s POS system can identify and subtotal Flex eligible items within a transaction and restrict usage of FSA debit cards to only the items that are covered under IIAS standards, requiring the customer to produce a second payment form for non-covered items.
