I had someone ask me an interesting question today, and I’m not gonna lie, I didn’t know the answer. But thankfully my friends at Barcoding Inc. did. Someone contacted me because they were looking for a UPC code that could be printed on paper and read by a barcode scanner, but couldn’t be viewed by the naked eye. Sounds a little like sci-fi huh? Invisible ink? But there actually is such a thing, it’s called an Ultra Violet Barcode or UV Barcode. My friend Kevin Berisso, Director of the AIDC Lab at Ohio University has helped me out by providing more information about UV Barcodes, read more HERE.
