Life is tough for a smoker: not only are you slowing killing yourself from ten different cancers, it's getting harder and harder to enjoy that rich, deadly tobacco in public venues. Smokers in most big cities are already accustomed to heading outside for a nicotine break, and now some are being confronted with a fingerprint reader called 'smokescreen' that controls re-entry to clubs and bars after they've sucked down those precious puffs of smoke. Made by UK manufacturer idscan, smokescreen is marketed as an easy way for owners to combat bracelet or hand-stamp fraud, and also keeps track of how many people are outside at any given time. Best of all, those nic-heads loitering for too long and killing the ambiance can be locked out after a preset amount of time, either forcing them to the back of the line or perhaps giving them the kick in the pants they need to quit.
