Companies that accept major credit cards will be barred from using WEP for their WiFi security, but not until mid-2010. The rule is part of new security standards defined and released this week by the Payment Card Industry Security Standards Council, which is made up of companies like Visa, MasterCard, American Express, and Discover.

In addition to pilfering over 45 million—and possibly as many as 200 million—credit card and debit card numbers, the hackers were also able to obtain other personal data from over 450,000 customers. This included driver's license numbers and Social Security numbers.
