Not sure but I do note there is 16 bits of information in that code. So 2^16 = 65,536 possibilities
Are you trying to work out what J-021 is?
Do you know if the barcode represents J- also? Or does it just represent 021 and the reader knows that the format is to have a J- in front?
What is the total range of the barcode? Letters, numbers, J-* or *-*** or something else?
Looks too difficult to me
edit: Okay so the top three marks are different and so I dont think that the barcode has the J- represented in it, unless there is some sort of decoding done at the end.

Did you get any further with this? Its intriguing but I couldn't see a logical sequence. Have you got any further background details on what the codes do or what they signify? The chip appears to be a 8 bit shift register, but what does it feed the scanned values to? Is there a processor with on-chip ROM code, or something running embedded software to process the barcode values?
I'm starting to see a pattern. Yep I should be asleep instead of trying to figure out how the barcodes are generated. Will hopefully post back tomorrow.
