Fuente: Wipo "digitalization" A method of unlocking restricted extended classes of features and functionalities embodied within an optical scanning system having an extended programming mode. The method involves providing an optical scanning system supporting baseline classes of features and functionalities, and having an extended feature class programming mode for programming extended classes of features and functionalities, in addition to the baseline classes of features and functionalities. A license key is assigned to the optical scanning system, for unlocking at least one of the extended classes of features and functionalities, and programming the optical scanning system to operate with at least one of the extended classes of feature and functionalities, in addition to the baseline classes of features and functionalities. A license is procured to unlock and use at least one of the extended classes of feature and functionalities, and obtaining said license key assigned to the optical scanning system. The said optical scanning system is caused to operate in the extended feature class programming. While the optical scanning system is operating in the extended feature class programming, the license key is used to unlock at least one of the extended classes of features and functionalities, and program the optical scanning system to operate with at least one of the extended classes of feature and functionalities, in addition to the baseline classes of features and functionalities.
