Tungsten could be the solution to making sure that these barcodes will be scannable for millions of years. Researchers have now come up with a way to make sure that QR codes can store information for extremely long periods of time by using certain etching techniques to hold every bit. This involves the use of optical information carriers that will be able to withstand the test of time. The method used by the researchers to create the QR codes and to preserve both them and the information that they contain…
