Lost and found: Japan tags dementia sufferers with barcodes:
A Japanese city has introduced a novel way to keep track of senior citizens with dementia who are prone to getting lost – tagging their fingers and toes with scan-able barcodes.
A company in Iruma, north of Tokyo, developed tiny nail stickers, each of which carries a unique identity number to help concerned families find missing loved ones, according to the city’s social welfare office.
