Our idea


The underlying patented technology allows for applying the mark on graphical image, QR code, Aztec code, barcode, etc, as Digital Watermark that can by verified against encrypted data. The digital watermark is made to be read by various devices, for example smartphones for ease of use, via dedicated app, available free on iTunes and Google Store. Thus system is reliable, simple to produce and use, and at lowest cost possible.
