TfL launched the Contactless Payment Card (CPC) option on the bus network in December 2012. The current communications campaign alerting customers of the potential for 'card clash' is to raise awareness in advance of the launch of CPCs to the rail network later this year.

On the bus network, when a card clash is detected, the customer will not get a green light to proceed; while on the tube network the gate will not open. Customers must then re-present the card they wish to use and then travel as normal. Customers are not penalised when this happens.

At the moment a very small percentage (roughly 1 per cent) of presentations on the bus network involve a card clash. In some isolated cases customers might present two cards to the reader but only one is detected - with the card that is charged not being the intended one. Around four refunds a day are being made to customers who have experienced this problem which is very low. Since their introduction, 1770 refunds have been made totalling £11,000.
