I agree with you not to sweat it, and that it is almost always totally safe. This was just a scenario that has always kept me wondering. Elaborating: I go to Europe, rent a car and go traveling, getting credit card receipts all over the place, not checking my bank, or Quicken, not even getting on line for 2 weeks (unlikely, but let's assume). I have no phone with me there and even if my old Dutch cell phone would work ever again, no bank has that number. If the bank calls my home number to question a charge made (really by me, or by someone else) how would that get verified? Would the bank just suspend the card?
I sometimes just "X" the signature, especially at those awful supermarket signature screens.
