My card reader keeps canceling the transaction, before the customer can even insert the pin number. First time it happened, I hoped it was only a one-off with this particular card. Later though it did the same to one of my regular customers. Canceled the transaction before inserting the pin tried again, this time the pin was inserted carefully, hardly moving the card reader, said pin ok, customer gave me the card reader back - transaction canceled again, tried one more time, this time leaving the card reader on the counter, payment went through ok This shows me that it is not a problem with the customers card, but the card reader. It seems to happen as soon as the card reader is moved, like lifted to insert pin etc. Have tried several times since then and when I tell customers to leave the card reader laying on the counter and to try not to move it at all, it works ok. (Makes me seem very unprofessional though.) Must be that the reader looses contact with the cards chip, which then cancels the transaction.
