Abstract
Methods are disclosed for transmitting information from a handheld device to a terminal. The information is encoded as a barcode pattern. The barcode pattern is generated on a display of the handheld device. A size of the barcode pattern is periodically modulated on the display while maintaining internal relative dimensions within the barcode pattern. The periodically modulating barcode pattern is displayed to an optical reader of the terminal.
