This would only be an issue for those that don't authorize with the issuer immediately when the card is read. The issuer would know the service code read by the pin pad and should be able to determine that it is incorrect based on the PAN read by the pin pad and the fact that the merchant is certified to support EMV. They could choose to decline the authorization at that point. Most payment processors that I'm aware of in the US do this. |
