Arsenal have used "ticket cards" for several years and apparently the reviews have been positive. From what I've read, they're even stricter in that they don't allow you to print out a paper ticket to use in lieu of the card.
You may need to budget the cost of reprinting tickets into the cost of season-ticket sharing. (We had a Caps partner last year who didn't pay his share in a timely fashion and so I reprinted all those games to hold the tickets hostage. He had to pay me the reprinting cost in order to get them back.)
