RFID: Combining Low Read Rates With Cyberthief-Friendly Long-Distance Accessibility

Among the more fascinating tidbits to come out of the Black Hat/Defcon show in Las Vegas last week was a demonstration that an RFID tag could be read from 217 feet away. The tester used two large antennas and ham radio equipment, reported Dark Reading

But retailers have been discovering the ability to monitor RFID at very long distances for years. That's the irony of RFID. How can something with such low read-rates at a distance of two inches—when you absolutely need it to be read—also be readable by a corporate spy across the parking lot? Admit it: Technology (and cats, by the way) not so secretly wants us all to fail.
