With the aim of increasing the quality in public transport, as well as to achieve greater transparency of revenues and expenses, KJKP GRAS Sarajevo introduces electronic ticketing system in public transport of passengers. In cooperation with Lupon Ventures, Penta`s validators of the latest generation have been installed in six buses of GRAS who drive on the line "Vijećnica - Dobrinja".

The system is, as noted above, implemented on vehicles of just one line, considering that it is a test phase, but afterwards the goal is to introduce ticketing system for all lines, in trams and trolleybuses, all modeled on Europe's largest metropolis.

Ticketing system from the passenger aspect works in a way where passenger puts smart card close to the validator which immediately after reading "takes" the amount of driving and shows at display the remaining amount on the card. The card can be supplemented at retail outlets listed on the official project website http://centrocard.ba, as well as online payment can be made.
