Transport for London (TfL) intentionally reduced paper ticket sales on the London Underground by promoting contactless payments. By adding a pop-up message on ticket machines, TfL encouraged customers to use contactless cards instead of buying paper tickets. Not only did this align with TfL’s goal of reducing magnetic stripe ticket sales, but it also saved customers money on fares. For example, a trip from Paddington to Canary Wharf would cost £6.70 with a paper ticket but only £2.80 with contactless payments. This small change led to a significant drop in paper ticket sales, making travel more affordable and convenient for Londoners.
