You dn't get billed anything when you touch in on a TfL bus with a 
standard [1] contactless payment card. If your card is accepted, the 
card's bank information is logged and later reported to the back office 
[2]. You are charged overnight with the amount that the back office 
calculates that you owe for the day. This is ticketless travel.

[1] Only normal debit/credit cards accepted, I think, i.e. not pre-paid 
cards.

[2] There is an authorisation process (in the report of the Mastercard 
New York trial on the metro I read that, when extending to buses, they 
were intending to use GPRS to talk to the local back office, with a 
small hot list in the vehicle's system as backup if the link was not 
available). TfL takes some of the risk - remember that the intention in 
London is to get people to travel, which is why the bus driver does not 
challenge people whose card is rejected or who simply don't touch in 
when they get on the bus.
