More people using anti-loss technology to locate belongings and even family.
SINGAPORE - It is a bit of home-grown technology that Mr Francis Fan relies on to keep track of his daughter.
His three-year-old enjoys running around says the director of an IT solutions company rather ruefully.
And it can be a problem in malls, especially when they travel overseas, which his family does often.
So Mr Fan, 35, has "tagged" his daughter - with the help of a Protag Elite card. It is slipped into a slingbag she always carries.
When she goes beyond a certain preset distance from the phone he is carrying, an alarm goes off.
He found out about the product in November last year, and has been using it for two months.
Innova Technology, the home-grown outfit that came up with Protag, says it is "increasingly common" for family members to use the device to keep track of one other.
Innova's business development manager Tay Jun Jie says that because the company has just started surveying its clients, they do not have hard numbers, but he knows of at least five people who are using the device to track their children.
But the majority of the 3,200 who have bought the product since it was launched four months ago are still using it conventionally, to keep track of items such as wallets, keys and mobile phones, says Mr Rick Tan, managing director of the company.
