security concerns. Is the QR code/link given in the QR code safe? Luckily there is an easy free solution available for everyone: the Avira Free QR scanner.
At least in my case, the family cemetery has around 90 percent of its inhabitants in a slightly different location than the layout map shows. I would really like to have more information about some of the departed. Would I do this with a QR code? Probably not. A separate QR signpost next to the gravestone might not be a bad idea. But first, this data should all be in clear text, on paper, in a secure location. And take the risk out of scanning QR codes.
