QR (Quick Response) code is a two-dimensional barcode that contains a large amount of data and can be quickly and easily encoded, generated or created, as well as decoded, read or scanned. Storing data within a barcode image is an easy and secure way to provide a potential customer with accurate information about a digital product. Your customers need to be sure about what they're purchasing. They want your original, they don't want a copy or different version of something looking like your branded product, which, actually, it isn't. Providing fancy barcodes with images, logos etc. is not a reliable way to ensure data integrity. Information contained within a QR code needs some sort of verification and the files are recommended to be digitally watermarked before they've been put on the market. Digital watermarks help us determine the authenticity of digital files as their globally unique identifiers. They also provide copyright protection for intellectual property in a digital world and give users access to publicly available information about the copyrighted work. Signing data with a cryptographic digital signature allows us to ensure data integrity and verify the identity/authentication of the copyright owner of the watermarked file. Our company deals with digital fingerprinting all kinds of files including images, audio, video, animated GIF and PDF files. Create a QR code containing information about your product and the corresponding digital signature and get it distributed to your customers, resellers or affiliates. The QR code can be read/decoded/scanned on this site, but it also can be read/decoded/scanned on any other website, or by using any QR code decoding app just as well. Combining barcodes and digital fingerprints is by far the best way for you to put your products up for sale.
