Just helping a friend check out the market potential here. I think this is a pretty seasoned product that we're all familiar with but somehow don't buy it because it's either not easily available here or just not aware of (not sure which).
The Anti-Loss Device comes in 2 parts - transmitter and receiver. It works like this: attach transmitter to any item which is valuable or easily lost. The receiver can go into your pocket or bag, whichever is convenient. If you walk a certain distance away from the transmitter, the receiver will beep/vibrate, warning you that you left something behind.
According to my friend, users can be anyone, from students (handphones, laptops) to mothers (kids) to businessmen/travellers (briefcases, luggages) to pet owners (dogs which tend to run away when you're not looking).
Warming mode can be set to either beeping or vibration (so it's either obvious or discreet). Distance can be set from 0-25m, so that it will not beep unnecessarily when you're just going off to get a drink.
I'm going to do a quick check, would this gadget appeal to consumers here?
