Debit Contactless Bug Fix

Previously, there was an issue in processing contactless debit cards. We’ve fixed this problem with an update. To reduce decline rates for Visa contactless debit card transactions, enable the “Enforce US Debit AID” parameter if your merchant faces a debit contactless transaction decline.

How to enable: S.T.E.A.M. -> Edit Parameters -> EMV-> enable ‘Enforce US Debit AID’ and click Save.
