A Japanese city is keeping track of elderly people with dementia by attaching barcodes containing personal information to their fingers and toes, officials say.
A company in Iruma, near Tokyo, has developed a tagging system for members of the public at risk of getting lost. The 1cm (0.4in) square stickers hold an address, telephone number and unique identity number for each user. The free service, launched this month, is a first for Japan.
The initiative, which uses a system of QR codes, was set up to help reunite family members with their elderly loved ones in the event that they go missing, according to the Iruma welfare office.
