I'm not liable for any fraudulent charges made with my card, and reporting mis-use is the work of a few moments (unless the bank notices it first and notifies me, in which case its even less work for me). A replacement card will be in my mailbox in a few days.
Is it a minor hassle to update the card number on file with various merchants I do business with? Certainly, and I'd rather such a situation if possible, but it's a minor inconvenience in the grand scheme of things.
That's the theory set forth by the banks; as someone whose cc info was compromised, it's not that simple. The "refund" on my debit card was conditional on the fraudster not contesting the removal of charges. Although the corrected balance appeared on my statement, the funds could be removed were the fraudster to appeal within 90 days. If I were to spend the funds on things like rent or food, I might get hit with overdraft charges if the appeal were made.
So, not only did I need a new debit card account, with all that entails, I needed to find out which merchant defrauded me, and the funds in question were frozen (practically speaking, unavailable) for months.
That was eight years ago; to this day, I have not (and will not) purchase anything from eBay (from whom the card info probably was sold) and there has been no repeat of fraud.
Buyer beware: eBay is not secure like an integrated retailer. Your cc info is probably more valuable than the meager profit the seller may realize on your "bargain."
