Barcodes That May Just Prevent Vomiting (and Death)
Two University of Rhode Island researchers and a company called SIRA Technologies have teamed up to create temperature-sensitive barcode ink.
The fancy "proprietary thermochromic printing ink, printed in a non-scannable color..emerges to a scannable, deep magenta when activated. It is therefore capable of adding a temperature and shelf-life monitor to any other barcode thus preventing the sale of contaminated food and archiving the incident."
In English, this means that your grocer can't try to kill you/make a buck with expired products because the barcodes will change color and become unscannable. Man, barcodes really might save the world.
