At this point, I just want one of these pay-with-your-phone solutions to win and be ubiquitous. The current situation is almost comical. "Do you have Venmo? Haven't set that up yet, can you send over Paypal?. No, what about Square Wallet? Nope, what about Gmail?"
It doesn't really make sense for me. I would much rather use a vendor that's sole purpose is to provide a means of money transferring. I don't need the convenience of typing a sigil followed by the amount to send money to friends. If I really can't electronically send them money, I will go out of my way to give them cash at a later date.
