A strange but true story, which is not gonna make you full of confidence. My mother's friend recently put her card into the machine and looked at her balance. When she tried to withdraw money it kept her card. When she entered the branch she filled out a form to get it sent back to her and left. On her way home home she was in her purse and found the card she thought had been chewed by the ATM. She then realised that it was her Nectar card which she had put into the machine. Finding this quite disturbing that she could look at her balance with a nectar card, she told the branch, who basically told her she was insane, to her dismay.
