Stagecoach have rolled out smart cards for their Megarider tickets, which I top up on a monthly basis and scan when I board the bus.
It would be nice for a more integrated approach to public transport ticketing locally (i.e. a ticket which could be used on other operators - TM / Hulleys - and on the trains)
Templeton is correct, & these Smart cards are getting very popular. Plus you can top it up on the bus if you don't want to do it online. Many big city bus operators have similar systems, some still with cash payments, which go into a secure cash box that the driver has no access to. In other words correct fare - no change given!
That would solve the problem drivers face at 5 a.m. in the morning when someone wants a £1.70 fare and offers you a £20 note. We are not (Stagecoach) supplied with a cash tray full of change. It's the drivers own money (I keep about £5 - in mine - loose change). Some drivers carry no float at all, & issue change vouchers for those who can't give the exact fare. Strictly speaking, if a customer won't accept a change voucher we can refuse them travel - no more "free -riding" just because we have not got sufficient change.
I'm sure I remember buses in the 70's with an illuminated sign on the outside saying "exact fare please" or words to that effect.
What REALLY worries me at times is that drivers making their way back to the depot after their shift are usually carrying significant amounts of cash, and as such, could be easy targets for an attempted mugging.
