Japan finds a new concept for QR codes - mobile-based epitaphs
QR codes (barcodes which can be scanned using a mobile phone) are on everything in Japan, from magazines to cereal boxes. In fact, the only place you’d struggle to find them is the local graveyard - although that’s likely to change in the near future.

Memorial designer Ishinokoe is to design gravestones with QR codes embedded, allowing passers to look up information on the deceased with a quick scan. Users could be sent links to websites with pictures or eulogies - sounds a bit quirky but could it be a natural evolution from the classic epitaph?
