A method and device for providing one-step payment approval and confirmation are disclosed. The device concurrently displays a data entry region and a confirmation region in a user interface of the device, where the data entry region is to accept user entry of payment data associated with a payment operation and the confirmation region is to require a sliding input to cause execution of the payment operation. While displaying the data entry region containing payment data received from a user, the device detects a user input in the confirmation region of the user interface. The device determines, in accordance with a predetermined criterion, whether the detected user input qualifies as a sliding input that follows a predefined motion path. Upon determining that the detected user input qualifies as the required sliding input, the electronic device executes the payment operation in accordance with the received payment data.
