I wish these advancements were more common. )-: Not only do I still see people struggle with failures, some machines seem to have received as their only upgrades a card reader and maybe a camera. Anecdata: one recent failure I'd never seen before is that a machine's card reader started charging $5 USD per transaction on top the advertised price. This showed up only on users' transaction records, but not on the machine itself.. The vendor blamed the credit card processing company, and the building's management taped an "OUT OF ORDER" sign over the card reader for a couple weeks while it got fixed. The people who noticed the overcharge and complained got refunded, but I don't know about the rest.
