I recently received a new credit card.
I haven't handled it much, but this one and second a recent card (within the last two years, new expiration and such) no longer have a strip on the back for yo to write your signature. No idea when this requirement went away.
But this new card is different in more than that way.
) and weighed several credit and debit cards:

Has anyone else seen this? Any clue what it might be? It may simply be a metal card.

- There are far more contacts for the chip (in the contact-pad on the face of the card).
- It is more rigid, though the same thickness. Almost as if made of metal.
- It is heavier.
- One the back you can see the small square where the chip is by slight indenting, as on my other cards. However there is also a slight outline of a far larger rectangle. Not extending to the card edges, and wider than the magnetic stripe, nearly twice so.
