The success of its mobile payment mechanism for iPhone and Blackberry introduced early this year led Starbucks to expand to Android the barcode-based payment. The app allows Starbucks patrons to pay at almost 6,800 company-owned Starbucks stores, more than 1,000 Target stores, and around 1,000 Safeway stores. With the Starbucks app, one can check the balance of Starbucks Card and reload using a credit card. It also locates the nearest Starbucks that accepts mobile payment, and track one’s Stars in the My Starbucks Rewards program.

With the launch of Starbucks for Android, joining the ranks of other smartphone apps, 90 percent of total U.S. smartphone users may now opt for a Starbucks mobile payment. Starbucks further positions the app as a convenient tie-in with the Starbucks Card, since paying by mobile is faster compared to other methods. Users will just have to touch the screen to pay, scan a bar code, and tap the screen again to finish the transaction. Here’s a short video about the app:

Starbucks considers itself a test case in the mobile payment system, and the benefits of such risk are evident. In just nine weeks after having an iPhone and RIM apps for payment, the company has completed around 3 million mobile payment transactions, achieved without any complaints on the system. The famed coffee company felt that the expansion to include Android is necessary and immediate, with surveyed customers clamoring for such app in Android. “Android is a huge growth opportunity for all mobile, so we’re happy to be part of that now,” said Chuck Davidson, category manager for innovation on the Starbucks card.

The catch? Everyone needs to line up together to pay, regardless of payment scheme. Davidson however mentioned that they are considering a separate line for smartphone users in the future.
