My CC just expired, do I have to remove the current card and re-add? I tried adding on the new card but SPay stated that the card is already in the system. The code on the back is different as well as the new expiration date.
I'm not sure, but am about to find out because my new card just arrived.
I guess you'll need to contact the S Pay help line and your bank to be on the safe side.
My card expired last month, I had forgotten about it and made a purchase with my phone yesterday, it went through normally.
I guess that your bank sends the new credentials (info) to Samsung Pay as soon as you activate the new card.
I activated my new card on August 30th and forgot to check Samsung Pay to see if I needed to change or do anything.
