Give credibility to important documents by sealing them with the COLOP e-mark secure solution. The printed QR-codes lead automatically to the corresponding verification app on the App Store. These QR-codes contain the one and only key to access all information which is fully encrypted and scrambled. For fast and simple authentication imprints, use the multiple-pages mode (User Registration needed). The following traceable details are then securely stored in a blockchain database: - Authorized Organization - Authorized Officer - ID Number of the stamp device - Location where the stamp was created - Date, time and number of the stamp For documents that require the highest security, use the scan-page mode. Besides above details, three more important pieces of information are stored: - Notes made during the stamp creation (optional) - Third party verification (optional) - Original image of the document
