Starbucks  is investing $25 million in Square  and plans to deploy its payment system in stores across the U.S., the companies announced  today. The alliance will put Square card readers--still a novelty in most parts of the country--within view of millions of Starbucks customers, and introduce them to the Square iPhone and Android apps.

As part of the deal, Starbucks president Howard Schulz is joining Square's board.
