Electronic ticketing systems have rapidly developed due to the advantages they bring to the client and the service provider, such as ease of use, the fight against fraud, increased transaction speed, increased reliability of terminals and cards and reduced maintenance costs. Moreover, an interoperable electronic ticketing system offers the public greater freedom and seamless journeys, and opens the door to collaboration with other urban actors, service providers and banks. In general, implementing an electronic ticketing system presents a real opportunity to give fresh impetus to a new service and customer relations.
