Square is officially at Starbucks today. In fact, Square Wallet is now available in 7,000 Starbucks stores across the United States.

There’s been no shortage of Square news over the past few years, but how does it work? If you want to test out the new Square Wallet option at your local Starbucks today, here’s what you need to know.

Setting Up Square Wallet

The first thing that you will need to do is download the Square Wallet app. If you have an Android phone, you can find the app in Google Play. If you have an iPhone, you’ll need to look in the App Store. This is a free download.

Once the app has been launched, you’ll note a number of stores in your area that allow Square Wallet payments. Today, you will see local Starbucks stores included in that list.

The Square app will ask you if you want to add nearby Starbucks stores to your virtual wallet. Tap the “Add to Wallet” button to add a store to your Square app. In the future, whenever you visit a store that you’ve included in your virtual wallet, you will see a barcode appear on your phone screen. You can then scan this barcode at a Starbucks counter, and pay for your purchase using your phone.

So, how do you add money to your Square Wallet?

Adding Money to Your Square Wallet

Square makes loading money into your Square Wallet easy. Just add the details from a credit or debit card, and the money you send to your Square Wallet will be stored. Why would you bother doing this? Well, for one thing, you don’t have to carry your wallet with you when you go to Starbucks. For another, there’s an additional Square feature that’s not available yet, but will be an excellent feature when it does finally arrive.

At some participating Square merchants, you can use your Square Wallet app in a different way. How? Square has a hands-free option that may be coming to Starbucks stores soon. By enabling this option, you can put your phone away and simply say your name in order to pay. If you don’t like to carry a wallet, Square Wallet is really the thing for you. What’s in it for merchants?

What Starbucks (and other merchants) Gets From Square

Merchants of all sizes pay lots of fees when processing credit and debit cards. Square allows merchants to skip these fees. Square also sets out to make paying easier for clients, and this, in turn, makes certain stores more popular.

So far, Square has had a tough time really exploding onto the U.S. merchant scene, but that’s mostly because large stores haven’t adopted Square yet. Starbucks is the first massive chain to accept Square payments.

Whether or not Square will be successful remains to be seen. Some people just prefer to carry a wallet over constantly loading an app with virtual funds. Others would rather just leave wallets out of the picture entirely.

Starbucks will be the deciding factor here. If you live in the U.S. and have a Starbucks near you, check out the Square Wallet app today.
