Abstract: A user makes a payment at a POS by entering the user's phone number (either through a keypad or via a card swipe) and PIN into a POS device (such as through a keypad). That information is communicated to a payment provider, who can then access the user's account, determine whether to approve or deny the payment, and notify the merchant of the decision.
