A QR or Quick Response code is a scanning code system that can be used to store and access digital details quickly and easily. All smart devices now seem to have the ability to scan QR codes directly, and it is a very useful function.
But did you know that QR codes can also be produced at a size so small that they cannot be seen with the naked eye? That is what a group of researchers from the Vienna University of Technology and alternative storage development company Cerabyte did, who have produced a QR code with a size as small as 1.98 square micrometers that has been listed as the world's smallest QR code by the Guiness Book of Records.
This QR code comes with pixels as small as 49nm and can only be read and scanned using an electron microscope. What's more, even though this QR code is the size of a germ, it can still maintain the nature and design of the code, allowing it to be scanned many times without facing degradation issues.
With this in mind, it is seen that storage manufacturing companies like Cerabyte can leverage QR scanning technology in their glass storage products, especially when these small codes can survive multiple scans, and glass storage is seen to have a very long lifespan.
