Why do I need to NFC scan and what will it do?

NFC (“near field communication”) serves multiple functions. NFC scan is needed to scan and start biosensors. After a 1-hour warm up period, users will start to automatically receive glucose data. NFC scanning retrieves missing data that was not able to transfer from the biosensor to the app. The biosensor will only keep the latest 8 hours of data collected. If the biosensor is scanned after the 8-hour limit has passed, the oldest data will be lost. You can also use the NFC scan to take a Glucose Snapshot, a summary report of your last 3 hours of data. The position of the NFC antenna varies in each phone. The position of the NFC antenna varies in each phone.
