Paris´ contactless smart-card for ticketing a telepayment system for pedestrian

The RATP transport network was among the first big transport companies to install an automatic fare collection system, with a magnetic ticket under the Edmonson format (66×30 mm). This system, more than 20 years old, has now reached its point of obsolescence. Moreover, it can´t meet the new ticketing needs which are: reduction of fraud by introducing systematic validation in the buses (revalidation of the ticket for each journey) and by preventing duplicating tickets (the low coercivity magnetic ticket can easily be duplicated nowadays); simplification of access in public transport; processing new tickets (the 64 bits of the Edmonson ticket have all been filled). To overcome these problems a system based on a smart card with a radio transmission to realize a contactless system, for which a specific study has been launched, is discussed. The testing of the system and its benefits are discussed
