Facebook will roll out PayPal as a payment option across its US services, including Messenger,  in a move said to make mobile commerce “smarter, simpler and more secure for consumers as well as merchants”.

PayPal users in the US will also be able to receive notifications in Messenger, initially offering a way to manage receipts for PayPal transactions “neatly in one place”.

“PayPal’s mobile-optimised experience, when combined with relevant, in-context commerce experiences, will help offer a compelling and frictionless commerce experience,” said Bill Ready, EVP and COO at PayPal.

“These new capabilities deepen our partnership with Facebook,” he said, which already allows consumers to call and pay for an Uber from Messenger via Braintree, a PayPal subsidiary.

What’s more, as Messenger, with 1 billion monthly active users, starts to roll out native payments, PayPal merchants will be able to accept PayPal payments directly in their bots.

“We’ve also helped merchants purchase Facebook ads, helped consumers buy headsets and content from Oculus, and continue to help PayPal-enabled businesses sell products directly from the ‘shop’ section of their Facebook Page,” said Ready.

Last month, Facebook said it was testing payments via Messenger to accelerate commerce on the platform by using credit and debit cards stored in Facebook or Messenger.

Sharath Dorbala, VP and general manager, mobile financial services at Amdocs, said that “with globally recognised names such as PayPal and Facebook” entering the mobile money space, “we will hopefully see a rise in confidence in these services and create a climate in which people want to engage with them.”

He pointed out there are 300 million registered mobile money users in the world but only 103 million are active.
