Walmart mobile payments roll out in 19 new states.

Walmart Pay is available in approximately 3,700 of its stores across the United States. Although it failed to reach its initial goal of launching the payment service to every store by the end of June, it added close to 1,300 stores in 19 new states throughout last week. Now, the total number of states where the mobile payments service is available has reached 37 and also includes Washington D.C., reported Chain Store Age.

The digital wallet service rollout started back in May 2016.

The service was officially announced by the monster retailer back in December of 2015. Texas and Arkansas were the first states to receive the service. Walmart’s payment solution – which works via the retailer’s mobile shopping app – launched at 600 stores across both states back in May.

Walmart Pay has a massive built-in potential customer base.

Currently, Walmart’s mobile app has 22 million active users. With such a huge consumer base, Walmart Pay has plenty of potential for success.

The mobile payments service from Walmart is easy to use and is one of the options on the retailer’s mobile app. Consumer with the app can choose the payment option at checkout, which activates their smartphone camera. With their camera they scan the code displayed at the register. The scanned code will connect them to Walmart Pay. Once the transaction is complete, an e-recipe is sent to the app. Customer can view this e-receipt whenever they want.

In addition to their own digital wallet service, the American multinational retail corporation also intends to accept other forms of digital and mobile payments within its stores.

While certainly not the first to launch it s own mobile payments solution, Walmart’s decision to rollout Walmart Pay could prove advantageous for the company. Although consumers aren’t likely to obtain many merchant-specific payment apps, it is the largest Tier I retailers – like Walmart – that have the highest potential to experience the most success with these services.
