Travelling by air
When travelling by air, put your FreeStyle Libre sensors in your carry-on bag.
You can go through X-ray machines while wearing a sensor, however we recommend you notify security personnel when going through airport security screening.
It is recommended that readers be powered off during a flight and not used for scanning. Please check with your airline and follow their policy on NFC devices and plan accordingly. The strip port in the reader can be used to measure blood glucose or ketones during your flight.
Take enough sensors with you so you have an adequate supply.
When traveling into a different time zone, adjust the settings for the time and date on your FreeStyle Libre reader.
