Walmart is a small player in the game of online shopping – but it’s hoping to leverage that by using apps to improve the shopping experience of its physical stores. The company has been testing out mobile apps for self-checkouts which have grown from 14 to 200 stores.

Walmart has created apps for every major device, but its Scan and Go self-checkout is only available for iPhones. The app uses location aware technology to find your store’s location. Once you select the in-store mode, you can scan your items, place it in your real shopping cart, and pay by transferring your mobile cart at the check-out stand. The app’s greatest asset is its ability to maintain a real-time total of the shopping cart, which is perfect for budget conscious shoppers.
