A California company is selling RFID tags that would take a counterfeiter years to duplicate. Microscopic differences between the tags–a side effect of normal manufacturing techniques–mean that each will yield different answers in a set of test calculations. A forger would have to correctly predict the results of 16 billion billion such calculations to be sure of accurately simulating a single tag. The tags are being marketed as a way for manufacturers to authenticate brand-name luxury goods.
