Friend buy you a coffee when you had no cash? Now you can pay her back on the spot with Square's new mobile payment system, Square Cash.
You can already do this with a lot of services like Venmo or PayPal, but now Square—one of the most popular and easy to use services for merchants—is opening up an insta-payment system for everybody. Through a mobile app for Android and iOS, you type in an amount, and Square will send it directly to your friend's email address. Square Cash is tied to your debit card, so the money goes directly to your bank account after a day or two. There are no fees, either. So easy, so simple, and such a good reason to never owe money to anyone ever again. [Square Cash]
