Agreed. Mag stripe tickets are now 40+ year old technology. There's no provision for tracking use on a specific number of non-consecutive days.

 
The only way to 'automate' a '3 in 7', '8 in 15' or 'x in y' type of Rover ticket is to sell it in the same manner as a flexi-season - i.e. on a Smartcard where it will imprint 3, 8 or x tickets and an expiry date on the smartcard.

 
They can't (sorry - haven't) get card and paper tickets to even work the barriers. I bought a FOSS the other week at Bath Spa, walked straight across and put it in the barrier having filled in the use day on the second part, and was told by the gate-line bloke that I had kept it too close to me phone in a sort of "you should take care of your ticket" tone.

I would conjecture that modern technology would allow the barriers and electronic gubbins to note on which day which particular ticket has been used and deduct a day from the stock accordingly - quite clever things are done with much more sophisticated cards and systems.

Looking at plans for linking tickets to credit / debit cards and "always offering you the best possible deal for your journey in walk up tickets", can I take that as a promise that when I'm out and about for a fortnight as I am at the moment that my fare total will be capped at the FOSS price?  It is, after all, the ultimate walk up. ticket!

 
If you need to write on ticket cards, you'll find "paper ticket" is rather a misnomer. The face is shiny, and even permanent markers may wipe off, and the back is absorbent and shiny so they smudge. All you can do is pick a fine-tip permanent marker and test, or if all else fails use a CD marker.

 
How do you mark off the days you travel?

 
Wouldn't it be easy if they did an e ticket version  ?? 

 
I think you'll need something with a finer point than a sharpie - the boxes are quite (very) small

Sharpie's smudge too.

 
For "Biro" read "Sharpie"  !

 
You might find a fine tip marker is better for writing on the tickets, be they card stock or paper roll.

 
Must make sure that I have a Biro with me then !

 
Paper tickets from ticket office or onboard only.

 
I am going to buy a FOSS Rover ticket next week. I believe that with the paper ticket you have to mark it with the date each day that you use it. How to you do this with an e ticket ?
