I went to America with mine, went through all the scanners, both ends, still works fine. I don't blame security for being cautious when someone is saying something they have cannot go through the scanner. As far as I'm aware it would take electromagnets to wipe flash memory and airport scanners don't use electromagnets, so I'm confused as to why Abbott would say they can't go through. I always keep a log of all my readings on my iPod and written in a diary so if the memory in my meter did vanish for some strange reason then it wouldn't matter anyway.
