Of course, I would love to see it used in more locations around me. Specially my local Tesco Express. I use it whenever possible, it was just the mention of Petrol Stations that was surprising unless people buy items without buying fuel but I imagine that is infrequent but I guess updating all POS system is done at once.
PCI (Payment Card Industry) have a security council that publishes a set of standards businesses should maintain if they process card transactions.
They're -very- thorough standards, and full compliance is a pain in the ass but gives you greater freedom from your bank etc.
Love it. Use it for everything I can - even to the extent that I will now avoid closer lunch places without it...
Wetherspoons use contactless systems
Going further away to save time entering PIN
Had a contactless card for years now, have tried to use it in McDs a few times but I've never been able to get the reader to "see" my card. There are no obvious instructions as to exactly where/how you're supposed to hold it and the staff look at you like you've got three heads if you try and get any subtle assistance from them so I usually end up just putting the card in the slot after a few seconds in order to avoid looking like a clueless idiot.
Never been quite sure whether my card wasn't working right or whether I was doing something wrong.
