At the Baja Beach Club, Tuesdays are VeriChip implantation days. Stop in and a ''nurse'' -- the club's word -- uses a syringe to inject a VeriChip capsule under your skin. There don't seem to be any rules about where on the body it has to be placed. If you think this sounds like something you'd never do, then you're not the kind of person who goes to clubs wearing your bestest nose ring.

Once implanted, you become your own credit card. Need to pay for a drink? Wave your implant near a reader, and you're done. VeriChip has dreams of going global with its ''human implantable ID technology'' -- once implanted, you could wave a body part to pay for a burger at Wendy's, a beer at a baseball game, or whatever.
