"You should probably buy a shredder today.
I get a heck of a lot of credit card applications in the mail.
A bunch for Visa, quite a few from Mastercard and tons of them from American Express.
I almost always tear them in half and throw them away.
Sometimes, if I am feeling particularly paranoid, I'll tear them into little bitty pieces.
Is that good enough? Could a determined and dexterous criminal gather all the bits, tape them together and apply for a card in my name? Would a credit card company balk when confronted with an obviously resurrected application?
A test was in order, and when the latest application arrived from Chase Mastercard, I was equal to the task."
