A ticket dating machine is a machine intended to validate the transport documents of the passengers of a means of Public transport. The dater modifies the ticket: drilling of a hole or a notch, writing of a code to ink, or modification of a magnetic track.

With the SNCF

The daters brought into service in the Années 1980 were of orange color. They carried out a notch in the tickets, and printed two information: the number of the day in the year, as well as a code identifying the station. Once the notch carried out in a ticket, the second composting was impossible.

Starting from 2004, a new generation of daters makes its appearance: these new apparatuses print in light the name of the station, as well as the date and the hour. They do not perforate the tickets, but draw a triangle in relief there.

With the RATP

The daters of the RATP read the magnetic track of the tickets, in order to determine if they are valid. They also modify this track, in order to indicate that the ticket was used. They also print the hour and the start date of use.

According to the models, the daters can be related to swivels or doors, in order to admit in the stations only the travellers provided with valid transport documents.

Recent daters the RATP also accept the master keys Navigo, based on technology RFID, which allow the identification without contact of the transport document.
