RFID tags can be read at a surprising range, a researcher has found.
When he's not listening in to GSM phone calls, Chris Paget has been busy seeing at what distance an RFID tag can be read, managing a respectable 217 feet.
Paget also reckons the US military could read an EPC Gen2 tag from 80 miles off, though the connection would likely time out before any data was retrieved. Which is a shame as his calculations put the theoretical maximum read range at 317 miles, if you've got a big enough dish.
