Selling physical products in a VR experience

I'm working on an app where users will be able to fill a cart with real, physical items. I'm trying to figure out how to perform checkout, it would be great if there was a one-click solution. Is there a way to use the built in quest checkout for physical items? It looks like it's geared towards digital, in-app purchases. What are my options here for allowing users to pay/checkout? The best I could find was to use paypal, although I'd really prefer an option where the user didn't have to type in login info.
