The excitement mounts!
I've just managed to activate my sensor, and am now waiting an hour before I can read it.
The phone chirped and the screen display changed.
Nearly had a heart attack when I saw the number 19:02 but calmed down when I read the text.
That is the time when I can take my first reading.
I think the NFC sensor is just below the mid line on my Samsung Galaxy S5.
I had a nervous time moving it about until it finally chirped.
Just to be clear about the time lag; if I have a finger prick test then scan about 20 minutes later that should be a comparable reading (because of the delay between blood and interstitial fluid showing glucose levels).
However, how crucial is this?
I assume that once I am getting a continuous graph out of the Libre sensor I can then cross match any finger prick with the Libre time line.
I assume it is far more important for those on glucose lowering medication so that they can understand the trends and predict highs and lows.
Thankfully(!) I am only using this as a general diagnostic tool to try and work out which aspects of my daily routine are affecting my BG levels.
