Disposal of metal credit cards is not as easy as you might think. But you can’t just cut it up with scissors and throw the pieces away. And if you try to use your office shredder, you’re going to ruin the shredder before you harm the card.So how do you properly get rid of such a card, while safeguarding your account number?
To get rid of a metal payment card, contact the issuing bank. Ask your bank for a Disposal Envelope, so that you can mail the card back to them. They will destroy the card for you, at no cost.
Alternatively, you can break out the tin snips, but returning the card using the USPS is the safest method, I think!
