I am not sure on this, but I received vouchers in the mail. I believe you exchange them for an AP style ticket at guest services on your first day of use. So, I think you end up getting whatever they issue for AP's. Not sure on this because we exchange ours in 3 weeks!!!!
You get a voucher that is exchanged for a paper ticket like an AP. Unless you plan on storing it with magnets, running over it with your car or washing it in your bleach load, it should hold up fine. If it doesn't, it's a simple matter to go to Guest Relations to have it replaced. They will work just fine with FastPass machines.
