I work in a Co-op. Operator just has to press PayPoint on till screen, swipe card, choose or type payment amount and take your money. One of the most simple PayPoint options going.
I found in past with my old card if magstripe wasn’t great quality it might take more than swipe. I’m guessing that could be why they’re delving in to menu options, as it’ll say unrecognised if it fails to read a card on first attempt.
