Having well-designed adjustment features that cater for a range of spectacle frames, it is also designed so that it can be easily removed by shop assistants.
Be aware! I will sound the alarm if you even think of disappearing with me!
I am a security tag for spectacles and spectacle frames. Customers can try on a pair of sunglasses, but I will trigger the alarm if they leave with it without paying for it.
This ultrasonic welded alarm device can be positioned at different levels on spectacle frames of different shapes and sizes on display in shops, yet still allowing customers to fit the frames with ease. Once secured on to a frame, a nifty detaching tool is used to unlock and remove the tag, now ready to be re-used.
