What if the FreeStyle Libre Sensors is packed in luggage, what about the scanners that luggage goes through either checked or carry on?
The FreeStyle Libre reader and the FreeStyle Libre Sensor can be exposed to common electrostatic (ESD) and electromagnetic interference (EMI), including airport metal detectors. Your FreeStyle Libre reader and Sensor can safely go through these when packed in luggage/carry-on or in the security tray. However, the FreeStyle Libre reader and the FreeStyle Libre Sensor should not be exposed to some airport scanners (i.e. x-ray and millimeter radio-wave). If in doubt about the type of security scan your FreeStyle reader and Sensor are passing through, notify the Security Officer prior to proceeding through the airport security checkpoint and request another type of screening to be performed by the Security Officer.1
