Proof-of-payment

Proof-of-payment (PoP) is a type of fare collection system used on many public transportation systems. Instead of checking each passenger as they enter a fare control zone, passengers are required to carry a ticket, pass or a transit smart card to prove that they have paid the valid fare. Inspectors or conductors may demand proof of payment within the system. Passengers without valid tickets are fined.

Overview

The proof-of-payment system is a trust-based system. It is based on the principle that most people will comply with the law, and that violations will be detected through random checks. This system is used in many countries around the world, including the United States, Canada, Germany, Switzerland, Sweden, and Norway.

Operation

In a proof-of-payment system, passengers are required to purchase a ticket or pass before boarding the vehicle or entering the station. This ticket or pass is then validated, either by a machine or by a conductor. The ticket or pass is then kept by the passenger as proof that they have paid the fare.

Advantages and Disadvantages

The main advantage of the proof-of-payment system is that it speeds up boarding times, as passengers do not need to show their ticket or pass to the driver or conductor when they board. This can be particularly beneficial on busy routes, where boarding times can significantly impact on journey times.

However, the system also has some disadvantages. It relies on the honesty of passengers, and there is always a risk that some people will try to travel without paying. This can lead to revenue loss for the transport operator. In addition, the cost of employing inspectors to carry out random checks can be significant.
