Hahahah as I suspected. But the pictuyre inspired me, it made me believe for a momentthat we do have a sort of point of sales app for steem hidden on the google play store this whole time! Sadly things are not this simple
but maybe this will inspire someone to build one
actually I know for Ghanians and users of Mobile Money lik4 in Nigeria to, 
RE: Imagine a Point of Sales App like this that allowed a resturaunt to accept steem! Anyone know what this Blockpay App does or why Steem is featured in the Play Store photo?
