Can you include Photographs in Secure QR codes?

One of the crucial decisions to be made while implementing QR code-based security in documents is the PDC vs. EDC decision. Very simply - PDC or Primary Data Code is a self-contained QR code that contains textual data and can be verified offline. EDC or Extended Data Code can have images and files. Still, since these are bigger, they are not stored inside the QR code itself but stored as encrypted blobs in storage (like AWS) and fetched using the key in the QR code hence need data connectivity. But can photos be included in PDC codes ?

Can Secure QR hold up to Blockchain?

The faster time to market, scalability, proven technology, efficiency, and effectiveness would make Secure QR code technology far more attractive for banks, financial institutions, the healthcare industry, and even the retail sector in developing countries compared to Blockchain.

In China and recently in India, the modest and unassuming QR code has helped the governments, large enterprises, millions of small businesses, and billions of users achieve a lot more at a fraction of the cost in two of their most significant initiatives in recent past – vaccinations as well as payments.

With the ability to democratize access, efficiency, wide acceptance, and effectiveness – it would be naïve for large governments and businesses to jump onto Blockchain at the expense of Secure QR codes without due diligence. Especially on the parameters of sustainability. Secure QR codes as technology can transform physical-digital transactions at a fraction of the cost of Blockchain systems, delivering speed and efficiency both in implementation and integration. With the power of mobile phones in the hands of consumers and the need for secure technologies, the world is at a cusp of transformation, and a Secure QR code holds the key to large-scale adoption.

Document Security

Globally, millions, perhaps billions of dollars, are lost each year due to fake or tampered documents. These may be phoney degree certificates, shipping documents, trade finance documents, bank account statements, hospital bills, laboratory reports, quality and inspection certificates, insurance policies or any of the thousands of possible documents & use cases. The problem has grown manifold because of the advancement of printing technologies that enable the generation of hard-to-distinguish fake or tampered versions compared to the original. One would think that the problem would have been eradicated over decades. Still, it has only increased significantly across industries in this period. Imagine this - even something as new as COVID negative certificates are now tampered globally with impunity, with fake certificates being issued to enable travel and reap many other benefits.
