Contactless technology

Ticketing is defined as the management of contracts linking a service provider with its customers. It covers all the operations connected with the issuing of a use and/or an access right, its selling, reloading, validation and controlling. Electronic ticketing uses a smart card type support, with an interface which is either, as required, with contact or contactless.

Above all, Calypso is the electronic ticketing standard which meets Transit operators' needs.

What is contactless technology ?

After using paper tickets, then magnetic technology, the 3rd generation widely developed nowadays is based on Smart cards using Contactless technology.


Contactless technology is based on inductive transmission, which is used in the transmission between a smart card and a terminal. The smart card holds and processes information, the terminal (validators, vending machines…) reads or modifies this information.


Inductive transmission offers several advantages:

  • contactless transactions
  • optimum speed of transaction
  • no need for energy supply on the card
  • ease of ergonomics
  • reliable (no mechanical system used)
  • less expensive than infra-red, offers the possibility for more applications


Furthermore, the use of a microprocessor allows for a high level of communication and security.

Contactless applications:


  • Ticketing: used for any type of ticketing, this technology has been particularly developed by the transit operators who can thus implement various transport contracts within the card's chip (season tickets, specific tickets…). This technology is particularly adapted to their requirements because it allows quick transactions, heavy volumes of trips, statistics collection and evolution of fares
  • Payment: An electronic purse for the payment of small amounts can be integrated in the card's chip. Being open to several applications, the payment function allows to generate a high volume of transactions, which is necessary for the efficiency of the electronic purse. In addition, the electronic purse is an easy way to ensure the interoperability between the various service providers who may also benefit from rapid transactions, where use of a contact card is impossible (not equipped or amount too small). Finally, the contactless technology avoids acts of vandalism on the equipment (no slot, no coins)
  • Services: Various loyalty areas can be loaded on the card. This zone allows to set up loyalty programs particularly adapted to marketing stakes between the different service providers (additional advantages for the customer, and tracking for the service provider). The benefit for customers to possess a tool bearing several services is obvious (all-in-one card)
