QR codes on tombstones help mourners to stay in touch
And the Japanese now even use QR codes on graves, as shown in the video below. It may sound macabre at first but seems to be a way to let people close to the person in question interact with each other without hassles, i.e. in the form of a mini social network that you can access with your mobile phone.
The mourners can also access information about who paid a visit to the grave recently, get the deceased person’s profile and other data or set up a virtual grave. Another example of using QR codes in this context can be found here.
