Fallback transaction

Fallback transactions are a phenomenon of the switch from old magnetic stripe credit cards to EMV chip cards. A fallback transaction occurs in retail settings when, due to equipment failure or attempted fraud, the EMV chip card reader fails to make the transaction, and the merchant is prompted to complete the sale via the old swipe method.
