Abstract:
1. A method of transmitting information from a handheld device to a terminal, said terminal including a digital imaging system and a platen separate from said digital imaging system, said digital imaging system having a depth of focus corresponding to a range of distances in relation to a surface of said platen, the method comprising: encoding the information as a barcode pattern; generating the barcode pattern on a display comprised by the handheld device; periodically modulating a size of the barcode pattern on the display while maintaining internal relative dimensions within the barcode pattern such that the periodically modulating barcode pattern can be displayed at a range of distances above the platen of the terminal; and displaying the periodically modulating barcode pattern to the platen and the digital imaging system by positioning the display of the handheld device facing said platen, wherein the periodically modulating barcode pattern together with the depth of focus facilitate accurate reading of said barcode pattern and flexibility in the positioning of the display of the handheld device in relation to the platen.
