日本出奇招防止老人走失 指甲上貼二維碼
A Japanese city is keeping track of elderly dementia sufferers by attaching barcodes containing personal information to their fingers and toes, officials say.
據官方表示，日本一座城市通過將包含個人信息的二維碼粘貼到使用者的手指或腳趾上，來追蹤走失癡呆症老年患者。A company in Iruma, near Tokyo, has developed a tagging system for members of the public at risk of getting lost.
距東京較近的入間市一家公司，近日爲容易走失的人研發出了一種標籤系統。The 1cm (0.4in) square stickers hold an address, telephone number and unique identity number for each user.
這個只有1平方釐米（0.4平方英寸）大小的貼紙上含有用戶的地址、電話號碼以及唯一的身份證號碼。
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.
入間市福利機關表示，此次發明使用的二維碼系統，將用來幫助家人找尋家裏走失的老人，使其團聚。The technology allows police to obtain details of a person's local city hall, along with contact telephone numbers and personal details, simply by scanning the code.
僅僅通過掃描二維碼，該技術便能讓警方獲取個人的地方市政廳、聯繫電話以及個人信息等細節。There are already ID stickers for clothes or shoes but dementia patients are not always wearing those items.
現在很多衣服或鞋子上已經有了辨識標籤，但是癡呆老人不可能一直穿戴着這些帶有標籤的衣物。Japan is facing an ageing population, with more than a quarter of its citizens aged 65 or over.
在日本，年齡超過65歲的人口已經佔到總人口的1/4，正面臨着人口老齡化的問題。This is set to increase to 40% by 2055, with the population expected to shrink from the current 127 million to 90 million.
到2055年，日本人口預計將由當前的1.27億減少到0.9億，而日本的老齡人口將增長至40%。
