Fare capping

Fare capping is a feature of public transport fare collection systems. In its most common form, fare capping credits the cost of individual transport fares towards the cost of an unlimited pass.

Some trials and proposals of fare capping were conducted in the early 2000s, with the first large implementation in London in 2005. Limited numbers of large transport operators began introducing fare capping in the 2010s, using proprietary technologies. As of 2023, fare capping is being implemented by smaller transport operators, using widely-available technology, with back-end systems in the cloud.
