“The Japanese city of Iruma has introduced scannable adhesive barcodes to tag fingernails of senior citizens with dementia who are prone to getting lost as a way to help concerned families find missing loved ones,” writes HughPickens.com, citing this article from Japan Times:
The adhesive QR-coded seals for nails — part of a free service launched last month and a first in the country — measure just 1 cm (0.4 inches) in size. “Being able to attach the seals on nails is a great advantage,” says a city worker. “There are already ID stickers for clothes or shoes but dementia patients are not always wearing those items.” If an elderly person becomes disorientated, police will find the local city hall, its telephone number and the wearer’s ID all embedded in the QR code. Japan is grappling with a rapidly aging population, with senior citizens expected to make up a whopping 40 percent of the population around 2060.
The article describes Japan as “a country where 4.8 million people aged 75 or older hold a license… Last month, police started offering discounts for noodles at local restaurants to elderly citizens who agreed to hand in their driving licenses.”
