OK, the Black Hats have found I have a Visa card by reading my slowly fading neurons' emissions. I wish them every success in generating the 12 digit card number plus the 3 digit security code plus my linked ATM PIN.
As suggested, they're probably better off using social engineering, looking for Post-it notes under peoples' keyboards or just straight out fingernail-pulling torture.
Penguin, cos they never forget their PIN (Penguin Identification Number).
