There’s a first. Stuck at the front of a growing queue at TESCO trying to pay for lunch with a Chip & Pin device that refused to work with either of my cards. The queue was growing at a rate and the state of the card reader was getting worse until it’s screen went illuminated but otherwise blank.
Power but zero data? The guy at the till kept hitting buttons in frustration, no managers coming to his aid.
Luckily for the customers the device was connected to the till via a coiled lead that joined in the middle with a RJ45 coupler. A quick disconnect and reconnect rebooted the device (I upset the guy a little in doing it but action was needed), it reported its RS-232 status as okay and moments after it accepted my card and I was on my way..
