Afterpay has struck deals with Apple and Google that will allow more people to use its payment service online and in retail stores.

The Apple Pay and Google Pay services will allow users to transact through Afterpay.

In the United States, the option will be available this month at retailers Forever21, Fresh and Solstice Sunglasses.

Shoppers with Apple Wallet on their phone will tap the card icon in the Afterpay app to pay at a store.

Shoppers with the Google service will need to tap their Android phone at a terminal.

Afterpay chief executive Nick Molnar said the deal with Apple and Google would attract new customers and drive sales for retail partners.
