The RATP ticket vending machines
The new RATP ticket vending machine for the Paris/ Ile-de-France network handles two forms of devices: magnetic tickets with magnetic strips or RFID technology smartcards with a no-contact system. The main feature of this ticket vending machine is obviously to provide a general public MMI (Man Machine Interface) with a touch-sensitive screen, and a second interface – specially dedicated to the visually impaired/partially sighted and non-sighted – with a touch screen and voice guidance.
