Pay For Your Starbucks Addiction With Your iPhone

If you’re addicted to Starbucks and have an iPhone, you can now pay for your caffeine-related purchases through the company’s iPhone app. Called Starbucks Card Mobile, the app has actually been in limited availability since last Fall at 16 standalone stores, and now lets you pay for cafe purchases at over 1,000 Starbucks-within-Target locations in the U.S.

There’s a lack of clarity over technical details and conflicting information besides, but what I can piece together is that the system uses either or both traditional linear barcodes and/or 2D images known as QR (Quick Response) codes.
