AfterPay, an Australia-based mobile app that offers 'Buy Now, Pay Later' installment options in key international markets, said it will begin offering Apple Pay online and in physical stores and Google Pay as an in-store option in the U.S. later this month.

The Afterpay service allows customers to make payment in four installation payments, without any upfront fees or interest, according to a press release.

"As we enter the second half of the year and retail re-emerges across the world, its critical we help our partners drive business growth," both online and offline," Nick Molnar, co-founder and U.S. CEO at Afterpay, said in the release. "As a proven solution for driving incremental sales and new customer growth, we are thrilled to introduce our new omnichannel solution to U.S. retailers as they begin to open their doors and bring shoppers back to their physical stores."

In order to use Apple Pay, customers can tap the card icon in the Afterpay app, which will activate the Afterpay card in the Apple wallet.

Forever 21, Skechers, Fresh and Solstice Sunglasses are among the first retailers to offer Apple Pay with Afterpay. Australian retail customers will soon get the option to pay with Apple Pay.

AfterPay currently operates in Australia, New Zealand and the U.S., and operates in the U.K. under the name ClearPay.
