NEWS: Wireless Security Flaws Plague Stores

<http://www.npr.org/templates/story/story.php?storyId=16553079>

An undercover survey of more than 3,000 stores has found huge holes
in wireless security networks.

When a store swipes your credit card, that information is broadcast
wirelessly. That means hackers can hop on the network and steal your
personal information.

A wireless security company, AirDefense, sent people with laptop
computers into 3,000 stores in major cities to see what sort of
electronic signals were flying through the air. In nearly a fourth of
the stores, transmissions between handheld devices and mainframes had
no security encryption. Another 25 percent used an easily broken
password.
