Abstract: Systems and methods for user choice of barcode scanning ranges are provided. This is achieved through the identification of a predetermined pixel-per-module threshold range. The pixel-per-module of a barcode being read by a reader is compared to the predetermined pixel-per-module threshold range, and a successful decode of the barcode is carried out only if the pixel-per-module of the barcode falls within the predetermined range. Thus, a user may select a desired reading distance range such that barcodes within a working distance range may not generate successful decodes if such barcodes are outside of the desired reading distance range.
