I think the electronic card system will be introduced later this year, but who knows.
And if the user unfriendliness of having to punch your ticket is so annoying, you can always buy a card (for 1 or 3 months) for the bus line you use. Unless you like the thrill of being caught without a ticket - in that case you should argue with the controller instead of paying with a smile - otherwise the experience is kind of incomplete :) .
