Article from C/Net Soured on stickers? Try Tattooed fruit
pear is just a pear, except when it is also a laser-coded information delivery system with advanced security clearance.

The marks are burned onto the outer layer of the skin and are visible to discerning consumers and befuddled cashiers alike.
