Scalable to less developed economies
Koldchain leverages the most affordable technologies to construct what is nonetheless a very clever solution. The SMS and 2D barcode scanning used for logging colorimetric shifts in the thermosensitive layer are free to the end user and extremely low-cost to the higher supply chain players (vaccine manufacturers, procurers, distributors and wholesalers). The thermosensitive layer is itself based off a cellulose substrate that is more or less just a few multiples of the price of ordinary paper stickers.
By introducing an infrastructure-agnostic mechanism for distribution network self-validation, Koldchain is levelling the playing ground for low resource societies to improve on the quality of cold chain products distributed in their markets and minimize the scope for diversions, dilution and corruption.
