NFC Temp Tracker is a new type of data logger designed for monitoring and recording temperature changes in conditions over time. It can be managed through a mobile phone with Near Field Communication (NFC) technology. Temperature data can be read and downloaded with a dedicated App which provides visibility and traceability of temperature-sensitive products like perishable foods or pharmaceutical goods during transportation. Users can be notified with an alarm when temperature is out of the set boundaries. Meanwhile, the thin and flexible label can be easily affixed to a container or product by its adhesive backing. This single-use and cost-effective temp tracker is an indispensable device to ensure product quality and safety in cold chain management.
