RFID Passport Required by Smokers
Now even vending machines are going to require ID when you want to buy a pack of smokes.
The system is being introduced in Japan in 2008 and is known as Taspo (Tobacco Passport), it uses RFID technology so that vending machines will only vend if you present your card (watch out for black market smokers passports on eBay).
Over in the UK we have a more capitalistic solution, vending machines sell packs of 20 which only contain 16 cancer sticks and cost way more than they do in the shops, as an ex-smoker I find this pretty amusing.
