I found a usability issue with the card readers today. The RFID reader is mounted on top of the pedestal facing up, and the optical scanner is near the top facing forward. If someone shorter than the pedestal is trying to pay, they will naturally stand directly in front of it and reach past the optical scanner to tap the card. That means it will try to scan their coat sleeve as a QR code instead of scanning the card, and leads to frequent failed transfers.
I'd seen it happen before, but only realized what the problem was today.
