Summary:A miniature barcode reading module for an electronic device minimizes the size of the memory of the processor die allowing the module to be used in small form factor electronic devices. The module may include an image sensor package operative to scan a barcode and a processor die coupled to the image sensor package. The processor die may include a processor, a memory, a flash memory, a plurality of barcode scanning algorithms loaded into the flash memory, and an image capture port operatively connected to the image sensor package. Barcode scanning firmware can determine if a barcode decoding algorithm is loaded in the memory, determine if the loaded barcode decoding algorithm is a correct barcode decoding algorithm or an incorrect barcode decoding algorithm, unload an incorrect barcode decoding algorithm from the memory, and load a correct barcode decoding algorithm into the memory.
