A startup hailing from far-flung Iceland is emerging as one of the key players in the race to distribute one of the key coronavirus vaccines around the world. Controlant — which has a unique real-time supply chain monitoring technology based on GSM networks and is specifically geared to areas like pharmaceuticals and life sciences — has confirmed it is providing its monitoring services to Pfizer as it delivers the mRNA-based Pfizer-BioNTech COVID-19 vaccine globally. The Controlant platform involves screen-based IoT tags, which link to GSM networks and then feed into web and mobile apps.
