With WalletPasses, you can use passes on your Android phone to check in for flights, get and redeem rewards, get in to movies, or redeem coupons. Passes can include useful information like the balance on your coffee card, your coupons expiration date, your seat number for a concert, and more. The app only consumes battery when you use it, no power consuming operations are performed in background. The app requires only minimal permissions to work and you keep full control of the data shared with pass issuers.
