Abstract
A method, system, and apparatus to scan visual codes are described. A first visual code of a plurality of visual codes to be scanned may be displayed on an electronic screen, the first visual code providing information related to a transaction facilitated by the point-of-sale terminal. An amplitude of a scan signal emitted by the point-of-sale terminal is measured and the amplitude of the scan signal and a threshold amplitude level are compared. Another of the plurality of visual codes is displayed on the electronic screen in response to the amplitude of the scan signal exceeding the threshold amplitude level.
