IamThermowatt allows you to find out if the thermostats and the heating elements are original, just holding your smartphone on the NFC logo printed on the carton box. NFC is a microchip device and the most innovative technological solution that replaces other easily reproducible solutions such as QR-codes or holograms. The unique “embedded” NFC tags are applied directly on the boxes, equipped with a serial number (which cannot be reproduced and cannot be falsified) and can be easily read by wholesalers and by their retailers through smartphone where IamThermowatt is installed. Fight the counterfeiting with Thermowatt!
