What is the IIAS?

There are currently over 31,000 national, regional, and local merchants using the Inventory Information Approval System (IIAS). When a participant swipes the Flex Card at a participating merchant, the system automatically validates eligible items purchased at the point of sale, and requires an alternate method of payment for ineligible items purchased at the same time. Consequently, further documentation is not needed from the participant for these transactions. This is great news for participants and makes the Flex Card even more convenient and easy to use.
