According to current credit card company policies, you may never really know if your credit card information has been stolen, because they simply don’t feel you need to know:
Companies such as J.P. Morgan Chase & Co., Citigroup Inc., American Express Co. and MBNA Corp. said that they are not automatically alerting their customers that their information may have been exposed but that they are more closely monitoring the accounts that may have been affected. The policy was reported yesterday on CNetNews.com.
Such credit-card-issuing banks said MasterCard and Visa have shared with them lists of account numbers that may have been compromised. Though such accounts may earn heightened scrutiny from the banks that issued them, customers may never know whether their account numbers were among those stolen by hackers.
It’s unfortunate that banks are willingly witholding this information from account holders. I think this weekend, I’m going to “lose” all of my credt cards and demand replacements… just in case.
