Reminder: Merchant Responsibility for IIAS Details in Flexible Spending Account Transactions
Region: US
19 May 2023
Merchants that are certified by the Special Interest Group for IIAS Standards (SIGIS) to accept flexible spending account (FSA) cards are responsible for ensuring that Inventory Information Approval System (IIAS) details are included in the transactions for all supported entry modes. Acquirers and merchants should be using test scripts provided by Visa to test the various POS entry modes for IIAS/Auto-Substantiation services.
Any new POS entry mode, such as EMV contact chip or contactless chip, enabled for a merchant is expected to be functional for any Visa card that is set up to use that specific entry mode, including EMV-enabled FSAs.
As a reminder, SIGIS-certified merchants, or their partners such as a gateway, value-added reseller, POS vendor or other third party , are expected to ensure that any specific services a merchant supports, such as IIAS, should work for all entry modes the merchant is enabled or certified for. By ensuring SIGIS-certified merchants are able to support IIAS for all merchant-supported entry modes, merchants can help reduce declines due to missing IIAS details and improve the cardholder experience.
