Easy to use! I haven't encountered any problems yet but there are lots out in that area so you never know what will come along next with new features being added or things just breaking down (I'm sure it's not your fault though).
If they could add more payment types like COD then even better!! It would be great if we can pay using our bank accounts instead as well because some people do their banking online rather than paper tickets/coins etc. Great system overall especially when everything runs smoothly without issues. There aren;t many complaints which makes me happy since this software was meant mainly towards commuters who don'T want anything complicated going against them once used - simple easy fares payable via app only option available at time of booking & no need buying multiple cards each month as needed previously when paying monthly passes through card machine.
