The installation of new "high tech" fare boxes on all 296 SamTrans buses is under way and will be completed by the end of the month, according to SamTrans officials.
The new fare boxes will accept cash, coins, tokens and paper magnetic-stripe tickets, SamTrans said.
They can issue a change card if a customer overpays and they will eventually be able to sell day passes.
SamTrans has been testing the new fare boxes since April, and will be providing a "how-to" guide to riders.
