Starbucks announced today that it has seen one million transactions via its mobile payment application. The full commercial launch took place on January 19th, 2011. The Starbuck application is available on iPhones and selected Blackberry handsets. A barcode is created on the display of a customer handset which is scanned (or entered) at a store point of sale.
While Starbucks does not release formal store visit numbers, my best estimates are that about 4.5 million people make purchases at Starbucks each day.  That means just under 1% (~0.8%) of transactions at Starbucks are now mobile in less than a month. Fascinating.
The company also said, it release an Android version of its app soon.
