How QR codes are adding a load more memory to loved ones' memorials

Some canny mainlanders have discovered a way to liven up their trips to the cemetery with a bit of modern technology.

Those visiting tombs of relatives during today's Ching Ming grave-sweeping festival may be surprised to see others at nearby graves huddled around a mobile phone, possibly shedding a tear - or having a good laugh.

Interactive memorials, featuring a simple QR (quick-response) code that can be scanned to access digital information, photos and even videos about a person, are finding a niche audience among the tech-savvy who may not want trips to the graves of friends and loved ones to be solely about quiet and sombre reflection.

With the space on most headstones limited, QR codes allow access to a vast databank of memories and information about loved ones, or even complete strangers, via a simple scan.
