iOS 6's Passbook app isn't just for big-business companies to use. Yes, you'll be able to use it to check in to your flights, and to get discounts at your favorite international coffee chain, but now mom and pop stores, your local food cart or even a stall at the local flea market will be able to offer you coupons and membership, using a new free app called People's Card.
