A Norwegian idea

The idea of Keep-it® arouse from a scientist that noticed that the writing on car park tickets disappeared in sunlight. That gave him the idea for a shelf life indicator for food, based on a combination of chemical processes, time and temperature. This eventually resulted in the “Keep-it® shelf life indicator”, which was launched in Norwegian supermarkets in 2012. By the end of 2017 Keep-it Technologies® has sold 40 million indicators.
