A browser executing on a computer terminal associated with a merchant receives a payment request for a purchase by a customer from the merchant. The computer terminal transmits, over a communications network to a mobile communication device associated with the customer, a push notification including the payment request and a set of instructions. The payment request indicates an identifier and amount of the purchase. The set of instructions causes the mobile communication device to activate a card reader using a mobile payment app, present the purchase amount to the customer on a touch-sensitive display of the mobile computing device, receive an acceptance of the purchase amount from the customer via the touch-sensitive display, and authorize the card reader to process payment for the purchase amount based on the acceptance. The computer terminal receives, over the communications network, a confirmation of the processed payment from the mobile computing device.
