Slashdot has a good article and thread going (which comes from the NY Times, yea i know registration required but neowin/neowin works quite well!) on the dangers of people reading the magnetic strip on the back of some US state driving licences, and it"s right in my HOME TOWN !!!
About 10,000 people a week go to The Rack, a bar in Boston favored by sports stars, including members of the New England Patriots. One by one, they hand over their driver"s licenses to a doorman, who swipes them through a sleek black machine. If a license is valid and its holder is over 21, a red light blinks and the patron is waved through.
But most of the customers are not aware that it also pulls up the name, address, birth date and other personal details from a data strip on the back of the license. Even height, eye color and sometimes Social Security number are registered.
"You swipe the license, and all of a sudden someone"s whole life as we know it pops up in front of you," said Paul Barclay, the bar"s owner. "It"s almost voyeuristic."
Mr. Barclay bought the machine to keep out underage drinkers who use fake ID"s. But he soon found that he could build a database of personal information, providing an intimate perspective on his clientele that can be useful in marketing. "It"s not just an ID check," he said. "It"s a tool."
