The blockchain-based Cert-Trace® technology is used to create and securely exchange important documents. Via a simple QR code (the one on the left works for demonstration purposes), all documents become accessible to the authorised person. It thus opens up possibilities for a massive increase in efficiency within the supply chain, for lifetime documentation and securing important documents. With the development of Cert-Trace®, TraCert OÜ is setting new standards in the digitalization of sensitive supply chains. TraCert OÜ are the developers and operators of the Cert-Trace® platform. The company has its headquarters in the Estonian capital Tallinn, where the operational tasks are handled. Estonia is known to be the digital Silicon Valley.
