The press release contains some startling facts;
- a third of all new Oyster cards issued with a 7 Day Travelcard or bus & tram pass on them are discarded after a week
- seven million Oyster cards have been issued to 700,000 Travelcard and 300,000 bus & tram pass season ticket holders. If I'm understanding this correctly, that means each season ticket holder has gone through an average of seven Oystercards.
I had always thought that the £3 deposit on pre-pay cards was to stop people exiting through gates (putting their cards overdrawn, which I think can happen up to £3), and then throwing the card away.
Given the facts as outlined by tfl, I think that the £3 deposit has to be a good idea. There is some shocking waste going on.
