BLOCKTAC is a leading European company commercializing authentication and anti-counterfeit solutions based on Blockchain technology. Our Blockchain certificates are sold to Fast-Moving Consumer Goods manufacturers (named "Digital Seals" in this case; currently mainly for Food & Beverages companies), idCards, professional and educational accreditations, artworks and medical records. We are also prepared to offer our service to other industries: perfume and cosmetics, fashion items and luxury accessories. In short, it can be applied to any product where it is handy to verify authenticity and traceability. Consumers, using their mobile phones, may scan the QR code to check it against the product's unique and uncopiable identifier. This allows them to authenticate the product using Blockchain or submit a complaint if it turns out to be false. We have reached four million certificates and seals across from clients in six countries: Spain, the UK, Poland, Colombia, Costa Rica, and Bolivia. We are launching the Blockchain of Things, aimed to develop disposable, autonomous devices that automatically grab data from the world and stores it in Blockchain. This innovation becomes the missing link between Blockchain, IoT and AI. Recently, we received the Seal of Excellence from the CE and a Neotec project from the CEDETI.
