Staples has revealed that Apple Pay is now the most popular form of payment in its iOS app, used for 30% of purchases made using the app. Apple Pay also appears to have driven new sales, with almost two-thirds of those transactions being from first-time Stapes customers, reveals FierceMobileIT.

Vemana also revealed that while Staples has both iOS and Android apps, with usage split pretty evenly between the two, Apple owners are more profitable, generating 70% of mobile purchases … 

“Apple Pay has been one of the most successful implementations when it comes to payments. […] Right now it’s the number one payment method for us in our iOS apps,” said Prat Vemana, vice president of mobile commerce for Staples.

Staples didn’t reveal stats for in-store use of Apple Pay, noting that it hasn’t yet made it to the top three payment methods there but that numbers are “healthy.” Staples began accepting Apple Pay in its 1,200 stores last November.

While Apple Pay has been enjoying considerable success in the U.S., now accounting for two-thirds of contactless payments through more than 60 banks and other financial institutions, a planned roll-out in China has reportedly been stalled by delays in reaching the necessary agreements and regulatory requirements.
