I'm a gold card-carrying member of the Starbucks' army, and I proudly use the free Starbucks Card Widget app for Android phones. With this app, I can display a widget on the home screen of my phone that constantly reminds me how much I have left on my card. Considering I frequent Starbucks on a daily basis during the workweek, this is a super-handy function. I love that I can also hit the "Touch to Pay" button, and up pops a barcode for the barista to scan, so I can pay directly with my Android phone. No more rummaging through my gym bag to find my gold card.
Before, if I accidentally left my gift card at home, that meant no venti skinny latte for me. The cool thing with this app is that you can track multiple gift cards at once, so if you lose one, simply buy and add a new one (but you need to register it online with Starbucks first to earn reward points). Or if you left one at home, never fear, you can pay via barcode with your Android phone. Smart, huh?
You can also access a list of your most recent transactions with a simple touch of the Starbucks Card Widget. If you need to reload, just tap the "Reload" button, and the app redirects you to Starbucks' website to add funds to your gift card with a low balance.
I'd like to see this app add a function that tracks the stars you've earned toward your next free drink — the whole point of having the gold card, duh!
