Mike Brewer of Wheeler Dealer fame was recently scammed for £10K,

was a Barclaycard customer who had his ID stolen, the fraudsters purchased a car from Mike's business and now he's lost his car and the monies. Since posting about his experience on Youtube he's been contacted by many other dealers that have had the same thing happen to them, but interestingly it always seems to involve Barclaycard customers. On the plus side Barclaycard seems to look after their customer but at the expense of the retailer. Surely all large purchases, say over 5K should require 2 factor authentication. It looks like the dumb old tech terminals that retailers use are not fit for todays commerce.
Edit from 7 min 50 secs for calling out Barclaycard
