Basically kills the need for PayPal for all peer 2 peer transactions where you don’t need buyers protection. They can’t file a dispute like PayPal. Good for Craigslist and such or splitting bills at a restraunt or paying a personal trainer. You just basically click "send xx" when in text and boom. It sign up for this pay you have to verify your ssn and a copy of your drivers liscense so the shouldn’t be toooo many scammers
