A system is provided for selecting a particular barcode on an item that includes multiple barcodes. The system (1) acquires, via a barcode imager, an image of the item within the field of view of the barcode imager, (2) analyzes the acquired image to determine a set of potential barcode fields, (3) determines, using a predetermined criterion (e.g., distance from center of imaged area, type of bar code, etc.), a candidate barcode field from among the set of potential barcode fields, (4) displays a modified image derived from the acquired image, wherein the candidate barcode field is identified within the modified image, and (5) allows the user to initiate a decode session when the candidate barcode field includes the desired barcode. The acquired may be modified to highlight the candidate barcode field in any number of ways, including, for example, superimposing an artificial reticule around the candidate field, superimposing an artificial scan line over the field, altering the contrast of the field, and/or altering the brightness of the field.

Described is a method and system for controlling usage of software on a computing device. An authorization key is generated as a function of a device string and a software string. The device string is a unique string stored in the device. The software string is a unique string stored in a software authorized for use on the device. The authorization key is encrypted using a private key and stored in the device. Upon a request to use software on the device, the authorization key is decrypted using a public key corresponding to the private key. A test key is generated as a function of the device string and a request software string. The request software string is a unique string stored in the software for which use has been requested. The authorization key is compared to the test key. When the test key matches the authorization key, usage of the software for which use has been requested on the device is permitted.

Methods and apparatus for decoding dataforms comprising integrating a dataform decoding module into a video processing system. In an embodiment of the invention, video data is analyzed for dataforms as it is being prepared for display on a mobile computer screen. Packaging a dataform decoding algorithm as a video display module allows many hardware devices to easily add dataform decoding capabilities.

Described are a device and a method for acquiring data using a camera port of a processor. The device includes a processing unit; a memory arrangement storing a set of instructions; and a camera port. The camera port is configured to receive first data in a first format from a camera-type arrangement. The camera port receives from a non-camera type data acquisition device second data in a second format and the processing unit converts the second data into further second data stored in the first format using the set of the instructions.

The device string is a unique string stored in the device. The software string is a unique string stored in a software authorized for use on the device. The authorization key is encrypted using a private key and stored in the device. Upon a request to use software on the device, the authorization key is decrypted using a public key corresponding to the private key. A test key is generated as a function of the device string and a request software string. The request software string is a unique string stored in the software for which use has been requested. The authorization key is compared to the test key. When the test key matches the authorization key, usage of the software for which use has been requested on the device is permitted.
