Laboratory barcodes pose real challenges. Tissue cassette cassette spend hours under vacuum pressure, submersed in paraffin, xylene and solvents before getting scanned. And cryogenic vials are stored at unimaginably cold temperatures for extended periods of time, before getting scanned. Barcodes on blood vials are round, not strait. They require perfect scan rates. Blood bags, wristbands and other patient identification assets all have their own barcode challenges.
