I had my Chase Sapphire Reserve card compromised a little while back and Chase shut down that number and sent me a new card. Normally they include a little mailer to send the old one back because they, like many high end cards to show off, are made of metal now. Thus if you try to put it into your paper shredder it may be the last thing that ever passes through the device.
However, there is another way to destroy them and I tested that with my old Chase Sapphire Preferred card that was also compromised a while back (see a theme here anyone)? But there is a subtle difference between that old card and the new Reserve card.
No not the metal as it seems the same but notice anything from the photo at the top of the post? Yep, a hole where the chip goes.
I have no idea why they have changed to this “holey” card, other than the fact that maybe some card readers were either being damaged by or damaging the units themselves by the raised chip and this way it can be more flat (again, just a guess).
Anyway, I just thought after all the hype around the new Chase Sapphire Reserve and the fact that they ran out of metal to make them for a while that it would be fun to see what it looks like on the inside! – René
