A few of my users have asked about other payment systems, on par with Paypal. Square has been raised, as has the ability to use Google Pay, Apple Pay, or the upcoming Amazon payments.
Basically, they want to leverage the larger payment platforms to reduce sales friction. Often times, people don't buy from an individual vendor because you have to fill out all of the info. It's the hassle factor, I suppose.
Is there a way to extend MarketPress to allow for other payment methods?
