I just want to make sure that I'm clear, I only key in the card when the card reader stops accepting the chip and it won't even say "Please wait" or whatever the message that appears was. This usually happens after the guest inserts their card at least three times. At my store, this never goes through under any circumstances (RedCard or otherwise) and the guest must put in their chip after the card reader is "reset". Otherwise, the guest would be stuck and unable to pay. Sometimes, swiping the card works but in cases that it won't, the guest wouldn't be able to pay and it would cause a needless delay and anger guests waiting in line.
