1. QR CODES
QR codes, short for Quick Response codes, are like "a bar code on steroids," Mann said. A QR code can contain a lot more information in a patterned graphic -- and they are can be scanned by many cell phones or smart phones. Somebody can point their phone at the QR code, and the phone could, for example, take them straight to a website.
Mann speculated that a QR code could be put on a headstone. A visitor could point their phone at the code and be taken to a website that allowed them to see a pedigree chart, join the family organization and get alerts on Twitter about any family history research.
