FreeStyle Libre 2, FreeStyle Libre 2 Plus, FreeStyle Libre 3 and FreeStyle Libre 3 Plus sensors can be exposed to common electrostatic (ESD) and electromagnetic interference (EMI), including airport metal detectors.
However, some airport full-body scanners include millimeter radio-wave, which you cannot expose your sensor to. The extent of these scanners has not been evaluated and the exposure may damage the sensor or cause inaccurate results. To avoid removing your sensor, you may request another type of screening. If you do choose to go through a full-body scanner, you must remove your sensor. If in doubt about the type of security scan you are passing through, notify the Security Officer prior to proceeding through the airport security checkpoint.
