Starbucks allows Android tablet users to pay for coffee the digital way.

The app functions as a frequency card. Instead of fishing through your wallet to find your card, you just whip out your tablet when it’s time to pay at the register.

You need a card with money pre-loaded onto it, and it must already be registered at the Starbucks website, but this only takes a few minutes. You can also use the app to add funds, set the app to automatically reload your card, check your balance, or view your rewards status.

Starbucks allows you to keep track of as many cards as you like. That way, if you share a tablet, you can put other card information into the app, or gift them to friends.

If you're a Starbucks regular, this is a great tool to have, and it means your Starbucks card is one less thing you have to carry around.
