A query has come up in the disputes sub-forum where a passenger refused to tap the reader of a TfL plain clothes RPI with their bank card. They hadn't seen a plain clothes RPI before and were scared of falling victim to a payment scam. A contributor pointed out how relatively simple it would be for a fraudster to set themselves up make a very nice illicit income this way. Should the practice of using plain clothes RPIs cease in Contactless ticket areas in recognition of the risk that it poses for passengers?
