QMC has developed a track and trace system that uses quantum dots, but the QDX Health ID does not use quantum dots. As part of the track and trace anti-counterfeit solution, the blockchain authentication platform described above was developed. It is only the authentication platform that is used in QDX Health ID. In the early days of COVID-19 and the lockdown, getting a company to adopt quantum dots for anti-counterfeit in a supply chain was out of the question. Hence the temporary pivot to use the authentication platform for COVID-19 tests and the launch of QDX Health ID. https://ledgerinsights.com/quantum-materials-deal-innova-medical-blockchain-authentication-covid-19-tests/ https://ledgerinsights.com/quantum-materials-deal-innova-medical-blockchain-authentication-covid-19-tests/
