Starbucks announced that Square Register devices will be on sale at 7,000 coffee locations. Starbucks is the latest place where the e-commerce gadget is available alongside Walgreens, Target and other stores.

Like the other locations, Square is actually charging $9.99 for the device with the list price credited to the user’s Square account. In other words, it is free as long as the user follows through with the purchase and follows through with Square. Users have been able to order Square devices for free online since the startup’s launch.

It is a great move for Square as Starbucks is the first natural brick-and-mortar fit for small, mobile purchases. Other retail outfits are either all-purpose big box stores, like the aforementioned Target, or tech-focused chains like Radio Shack and Best Buy.

To Starbucks advantage, any business deals are made over coffee, so entrepreneurs will have an easier time joining Square for an unexpected sale. More broadly, if a person is buying coffee for a group of people, he or she could get paid back via the device.

This will probably be the first of many physical space moves Square will make in 2013. Just last month it launched a gift card program for users to send or to redeem within Square.
