Faster checkout with invisible barcodes? New Seasons will give it a try

Upscale Portland grocery chain New Seasons is about to try something different. It's signing up to use technology from Beaverton-based Digimarc Corp. that embeds invisible barcodes all over a product. They're not visible to human eyes, but scanners equipped with new technology find Digmarc's barcodes right away, because they're everywhere on the packaging.
