Thanks for the feedback. Sincerely appreciate it. It's simpler for several reasons...
1. You don't need a credit card.
2. You don't need to be physically with the person or business you're paying.
4. In a store setting there would be no more waiting in a checkout line to pay.
5. Sending one Tweet is certainly simpler than pulling out a wallet, swiping a credit card, waiting for a response, then signing.
I honestly can't think of an instance where that would come up in my daily life. How is this simpler than regular credit cards and Square?
