Abstract

This patent specification describes operations of a mobile device with barcode-reading capabilities and an application and license server. A mobile device may include a barcode-reading application downloaded from an application server. The barcode-reading application may operate in a base mode or an enhanced mode. In the base mode, the barcode-reading application may establish a network connection to a licensing server to obtain a license code, and determine at least one operating permission authorized by the license code. In the enhanced mode, the barcode-reading application may implement at least one enhanced barcode-reading function which corresponds to the at least one operating permission authorized by the license code. For example, the enhanced barcode-reading function may be a function of decoding a barcode symbology that the decoder is restricted from decoding in the base mode of operation.
