J.P. Morgan Chase is putting its “Chase Pay” digital wallet on Walmart’s website and in the retailer’s Walmart Pay app, hoping to give customers more ways to make purchases without cash, a bank executive said on Thursday.

Kevin Watters, chief executive officer for cards at J.P. Morgan, said at a conference the bank is trying to make sure its Chase cards are an option for customers who want to make digital payments.

Payments with smartphones and digital wallets, such as Apple Pay aapl , probably won’t account for even 1% of transactions “for a while,” and will ultimately catch on in unpredictable ways, Watters said.

“We want our card to be wherever our consumers want their card to be,” Watters said.

As Watters began to speak, the bank said it reached an agreement with Walmart Stores wmt allowing shoppers to be able to use Chase Pay. The service is to be launched later this year.

The bank has already made deals with Best Buy bby and Starbucks sbux to accept Chase Pay.
