The logic is in the system to deal with transfers as they already do this for most of the transit authorities surrounding the TTC and with Go Transit co-fares. It's down to the TTC to agree their transfer policy and have Presto implement it.
In the same way, most of the surrounding authorities have the capability of a monthly pass. This will come to TTC, but there isn't much point until they have finished rolling out the card readers to all the subway stations, streetcars and buses.
Presto is fairly unique in the farecard world as it encompasses so many different transit authorities each with their own policies and fare structures. It then works out the best possible fare for your journey as you progress tapping your card. The existing systems could not cope with this at the time Presto was started.
