The Smart Ticketing Alliance (STA) was founded in 2015 as the follow up to the IFM project. The objective of STA is to promote and facilitate cooperation between national and regional Smart Ticketing schemes and to establish interoperable "Smart Ticketing" in Europe and elsewhere. Smart ticketing originated from the wish to have interoperability between upcoming regional and national public transport electronic ticketing systems. To achieve this, focus has been on the customer media while allowing for the concept of dynamic and multiple applications. The Alliance drives a coordinated effort towards global ticketing interoperability for the public transport sector. This includes the establishment of a trust scheme that mirrors the schemes used in the mobile phone industry, banking sector and with other stakeholders.
