A pear is just a pear, except when it is also a laser-coded information delivery system with advanced security clearance.

And that is what pears - not to mention organic apples, waxy cucumbers and delicate peaches - are becoming in some supermarkets around the country. A new technology being used by produce distributors employs lasers to tattoo fruits and vegetables with their names, identifying numbers, countries of origin and other information that helps speed distribution. The marks are burned onto the outer layer of the skin and are visible to discerning consumers and befuddled cashiers alike.
