Handbag Guard

Hi all!
I'm an industrial design student at Brunel University in England.
I'm currently in the process of designing a product called Handbag
Guard, and would really appreciate any comments or suggestions, and if
you could fill in a quick multiple choice survey for me?
The survey is at:
http://www.michaellam.co.uk/HandbagGuardSurveyII.doc
The idea behind Handbag Guard is that it lets you know when a
pickpocket tries to steal your handbag, or individual valuables from
your handbag. It consists of a small device, about the size and shape
of a mobile phone which you keep inside your handbag, as well as a
fashionable bangle on your wrist. Whenever Handbag Guard detects any
suspicious activity, it sends a message to the bangle, which vibrates
to let you know discreetly that someone is trying to steal something!
The technology used in Handbag Guard is fairly new – it uses rfid
technology. It requires that you stick a very tiny sticker on any
valuables you would wish to track.
If you have any suggestions, questions or ideas please let me know!
Please fill in the survey too, (and email or msn it back to me) thank
you!

Kind Regards
Mike :D
