Walmart Stores said on Wednesday it has completed the rollout of its Walmart Pay mobile payment service across the United States and that 88% of transactions on the app are from repeat users.
Overall transactions in the service, which the world’s largest retailer launched in December, jumped 45% in the last week, company executives said on a conference call.
Walmart did not give details on the rise in transactions since the launch, or the number of users using the mobile app in its stores.
U.S. retailers have launched a series of mobile payment apps in the last two years, but customers and merchants have been slow to adopt them.
Walmart Pay is available on Apple and Android devices and allows payments with any major credit, debit, pre-paid or Walmart gift cards.
