Amazon is making a push to get its Amazon Pay digital wallet into restaurants, gas stations and other merchants that it doesn’t directly compete against, according to a new report in the Wall Street Journal.

The move is an effort to challenge Apple Pay, which is the dominant mobile wallet in the U.S., and grow its share of a payment market that remains relatively weak domestically compared to widespread use of digital wallets in Asia and other regions, according to the report.

The report does not detail how Amazon Pay would be used at checkout under an expansion. Similar products from mobile device makers like Apple and Samsung allow users to scan the using smartphone at checkout, while Google Pay, which makes its own device, is used in combination with phones using the Android OS.

Apple Pay was accepted at about 5 million locations as of May, according to the report. 

In Asia, Alipay and WeChat Pay are the leading apps in the space.

An Amazon spokesperson declined to comment on the report saying it is rumor/speculation.
