Edible Barcode Expands Applications with New Handheld Reader

With a new, handheld optical reader, product authentication company TruTag Technologies Inc. (Kapolei, HI) says it is expanding the scope for which its edible barcodes can be used. As opposed to security measures like universal product codes (UPC) or radio-frequency identification (RFID) that are used on a package to authenticate products, TruTag’s edible barcodes are part of the product itself, including products like food and dietary supplements.
