I've just recently request a different design on my Discover More. Once I activate my new card, would my original card still work? One CSR said they don't deactivate any card because some people prefer having a few cards, and another CSR said it will be deactivated.
Anyone requested a different card from Discover and had both of them work?
I chose the ocean design btw.
I would assume it would work but it may be based on the way you requested:
There is an option to add an additional card with a different design, and an option to replace a worn or damaged card with the current design or new design...
All in all-
I have 3 cards with 3 different designs that all work
I don't think, the card companies have any way to force your old card from working (unless they change your card number)
