Add custom price-encoded barcodes to Unicenta (open-source)

I need someone to edit Unicenta (open source POS system), to be able to recognize barcodes in the following format: 0XXXXXXYYYYYY Where XXXXXX is the order number (ex. 004937) and YYYYYY is the price (ex. 000611 = $6.11). So for example the barcode 0004965004294 should translate to: Rx #0004965 with a price of $42.94 This should be very easy for someone with some knowledge of Java. You just need to modify the code, compile the program and ensure it works as I stated above. Provide me with both the source code and the compiled version and thats it!
