A few days ago my wife received a letter from our credit union, excerpts follow:
"Important information regarding your- MasterCard Credit Card
Dear Member: Visa and MasterCard's Fraud Control has advised XXXX Credit Union that 11,788 Visa accounts and 13,489 MasterCard accounts were potentially compromised by a third party merchant.
Preliminary investigations have confirmed that the merchant's computer system was storing *full magnetic strip information* (emphasis added). To remedy this vulnerability, the merchant is working to remove magnetic strip data from the merchant's systems, and is in the process of disabling the system from storing this type of information in the future. Fraud activity has been reported in USA, Great Britain, Spain, Italy, Turkey, Canada, Mexico, France, New Zealand, Sweden, Germany, Switzerland, South Africa, Portugal, Taiwan, Korea, Japan, and Hong Kong.
To avoid any future fraudulent activity, your existing card has been blocked from any future authorizations."
I don't know what data is contained in the "full magnetic strip information", but apparently if could be your life story.
Between this kind of thing and the Choicepoint mess
