Seattle-based Starbucks will acquire a minority stake in Square and CEO Howard Schultz will become a director.
Other companies including rivals Google (Nasdaq: GOOG), the No. 1 search engine, and Apple (Nasdaq: AAPL), the world's most valuable technology company, have also announced plans for using "digital wallets" for e-payments.
