<P> A transfer allows the rider of a public transportation vehicle who pays for a single - trip fare to continue the trip on another bus or train . Depending on the network, there may or may not be an additional fee for the transfer . Historically, transfers may have been stamped or hole - punched with the time, date, and direction of travel to prevent their use for a return trip . More recently, magnetic or barcoded tickets may be recorded (as on international flights) or ticket barriers may only charge on entry and exit to a larger system (as on modern underground rail networks). </P> <P> Fare cards will reduce or eliminate the need for transfers as the holder can validate a change in the direction of travel . </P>
