Book public transportation ticket online feature

As a daily public transport user i ussaully skip the Light rail at the moment i'm getting my ticket from the ticket window.
In this shot i tried to implement a feature wich is online booking to the Tunisian app of public transportation Wassalni i think this feature will save time and give us a one step further in the digitalisation process in Tunisia.

This shot is inspired from a previous work of @Vlad Ermakov.
