What is Downgrading?
Transactions are downgraded when they don’t meet interchange requirements, such as not capturing the correct card information at the point of sale, settling the transaction after a deadline has lapsed (typically 24 – 48 hours after the authorization) or manually entering rather than swiping a card. A downgraded transaction results in a higher cost for the merchant.
