Some random distant memories about the GMT ClipperCards:
- The cards were a bit of an inconvenient shape & size – skinny enough, but just a bit too tall to conveniently carry around in a pocket or wallet. The cards were a bit temperamental about working in the cancelling machines if they got creased or folded.
- There were around four adult versions of the ClipperCards, depending on the fare, plus one for the concession flat fare. I think later there were also cheaper version(s) valid in off-peak period only and one for young people between 16 and (maybe) 19.
- I suspect when first introduced the ClipperCards might have been printed with an actual fare value, but this was quickly changed to generic fare bands - obviously there would be a large amount of pulping and re-printing of cards every time there was a fare increase.
- Cards for different fare bands and the off-peak / concession versions were printed in different colours. I think these included some characteristic 1970s shades of brown, purple etc. but luckily the one I needed was printed in a sensible blue.
- On the All Night buses charging double fares, you were meant to clip your ticket twice.
- I’m not sure about the rule for two or more people travelling on the same Clipper Card. Certainly, they were transferable (i.e. you could borrow someone else’s and didn’t need a photocard like the SaverSeven season tickets of the same era). But not sure whether two people could legitimately travel together on the same bus by clipping the ticket twice.
