The difference between this system and that of the smart bus - if i remember how the smart bus system works - is that there is no deducting points or card credit for the distance travelled, once the card is paid up you have unlimited travel in the city for a month. The idea is to get all commuters who do the daily commute to buy the card then the revenue is shared to all the players to keep the services running.
If the human brain were so simple that we could understand it, we would be so simple that we couldn't. - Emerson M. Pugh
