Biometrics for handbags

Well gee, this certainly seems like a good idea. A fingerprint scanner that attaches to any handbag, thus allowing only a registered user to open it. No way that
type of security could be bypassed. No way to, you know, cut the bag open or anything like that. Sure it might stop casual snooping, but here's a better idea: don't leave your handbag lying about unattended and don't associate with people who you don't trust enough to not go through your stuff. Simple.
