German mason Timothy Vincent looks at a QR code engraved in a gravestone in the Austrian village of Boeheimkirchen about 65km west of Vienna. Austrian bereavement company Aspetosis is working with stonemasons to test technology that lets QR codes get sandblasted onto gravestones directly at cemeteries at a fraction of the cost of traditional methods of chiseling text or images onto memorials. All you need is a smartphone equipped with a scanner to read the so called "quick response" (QR) codes, to unlock a trove of information for the curious.  - Reuters/Leonhard Foeger
