If you want to use a traditional credit card (inside of Paypal or GPay), your options are currently limited. Shopify has the best implementation of this tech with ShopPay ... if you pay at any Shopify merchant, you have the option for Shopify to remember your digits. This streamlines checkout to a click or two. That's the big USP of models like this - speed of checkout.

How are options limited by PayPal and GPay? What is a "traditional credit card"?

I assume it means paying he merchant directly with the credit card instead of paying PayPal to pay the merchant.
