Re: Vein ID
Lifting the vein pattern would be easy - if it ever gets cheap enough to put in a smartphone, it would be cheap enough to put in a decoy replacement door knob or handle to lift your target's vein pattern.
I disagree. You leave fingerprints all over the place, so if <random thief> wanders into your hotel room, there will always be a nice helpful copy to start from, whereas you have to get your target walking into a controlled situation to get a vein map - it's not something you can obtain as a spur-of-the-moment idea.
If you're prepared to go that far I suspect you would be better off feeding your intended target some drugs (assuming they don't bring their own drinks glasses) and do whatever you need to do while they're out..
