Open specifications

The Open Ticketing Institute (OTI) supports the trend in the public transport industry to move towards interoperable e-ticketing systems of national scale with open specifications and standards.

As secretary to the e-Ticketing Schemes Association in Public Transport, OTI organises a bi-annual meeting of (mainly European) e-ticketing scheme providers who exchange experiences with respect to project implementation, technology and security.

OTI has become a liaison member of the Open Standard for Public Transport (OSPT) Alliance. For additional information, please visit
