The Japanese city of Iruma is advocating a new policy to help treat people with dementia. Officials unveiled tiny nail stickers, each of which contains a unique QR identity number to help track senior citizens with dementia.
The free service, the first of its kind in Japan, was launched this month to help elderly citizens who may get lost due to their illness.
Police can obtain an address, telephone number and other info by simply by scanning the small, water-resistant code. The stickers, which stay attached for about 2 weeks, can also be applied to key chains or shoe seals. The World Health Organization estimates that around 36 million people suffer from dementia worldwide.
