To use the Square Wallet, users must first download the app on their iPhone or Android smartphone, register their email address to create an account, and sign in.
After then registering their debit or credit card details with the app, customers can buy goods by tapping ‘pay here’ on their smartphone before scanning a related QR code presented by staff at a cash register.
Customers can also use the mobile wallet application to explore nearby businesses, as well as browse menu information, store hours and transaction history.
Users must have Android 2.2 or iOS 5.0 installed on their smartphones in order to install the Square Wallet application.
Starbucks said its new mobile wallet app is integrated with its Starbucks Card and My Starbucks Rewards loyalty programmes.
In August, Starbucks invested $25 million in Square Wallet, which was started by Twitter co-founder Jack Dorsey.
Starbucks CEO Adam Brotman said, “Starbucks was the first national retailer to offer its own mobile payment technology combined with a world-class loyalty programme in January 2011, and we have seen a tremendous response from our customers, with more than 100 million mobile transactions occurring in our US stores since its launch.”
William Henderson, Square Wallet director, added, “Square Wallet gives people an easy way to pay at Starbucks and neighbourhood businesses. We’re excited to work with Starbucks to introduce a broad new group of people to the benefits of using Square.”
