I’m not too sure about the specifics on the cards. I know there’s some issues with some cards. I’ve been waiting to search the forum for the info til I get a card that features tap to pay. If by contactless you mean just placing the card on the reader instead of swiping or inserting the chip, you might be able to get it converted.
The Apex is fully capable of doing tap to pay right now, but Mastercard might not allow it for 10+ years from now.
