Near-Field Communication (NFC) has transformed Blood Glucose Monitoring (BGM) by enabling "Flash" glucose monitoring and enhancing traditional meter connectivity. The technology's primary impact is best exemplified by the Abbott FreeStyle Libre, which uses NFC to allow users to scan a sensor for on-demand data retrieval, utilizing energy harvesting to keep the wearable component small and disposable.

Beyond sensors, NFC in traditional meters (e.g., Menarini GlucoMen Areo) facilitates "tap-to-transfer" data logging, overcoming the pairing friction of Bluetooth. Furthermore, NFC enables Smart Packaging solutions where test strip vials communicate calibration codes, expiration dates, and cryptographic authentication to the meter, providing a robust defense against user error and counterfeit products.
