What is near-field communication (NFC) and how do I know if my phone has it?

NFC is the wireless communication technology that enables your FreeStyle Libre sensors to wirelessly transmit data to another device.

For Android users: Your Android phone must have NFC capabilities and NFC must be enabled. Many of the latest Android phones support NFC. Check your phone's manual or go to the phone’s Settings menu and look for settings related to ‘NFC’, ‘Connections’, ‘Sharing’, or ‘Wireless & Networks.’

For iPhone users: You must have an iPhone 7 or higher running iOS 11 or higher to utilize the NFC capability needed to scan the FreeStyle Libre sensor.
