The other quirk is one that came up on this list six months ago of Faraday cages, given the aggressive rollout in the UK of contactless cards. Here it is not that you need the technology, rather that the technology will try to debit your account without you noticing, as I witnessed while queueing (another quirk of the UK) last week when the terminal reported that the amount was too great for the card because the limit for contactless operation is currently 20 pounds and the transaction was for 50 - the customer was waiting to insert his card for chip and pin operation but the contactless machine had got there first. If you have more than one card, then this can be a problem Tom Petch. > Regards, > John Levine, johnl@xxxxxxxxx, Taughannock Networks, Trumansburg NY > Please consider the environment before reading this e-mail. > > PS: I have a Chip+PIN Amex card, which was a major pain in the patoot to > get. >
