Update 2/16/21: Chase is now sending out an email that Chase business cards can be added to mobile wallets. It’s still not showing at the official link, but it now appears that Chase business cards should be able to be added to all mobile wallets. The email referenced INK cards, but apparently all Chase business cards are working now. Hat tip to reader Alberto
Most Chase cards have long been used with Apple Pay, including personal credit cards and business debit cards, but Chase business cards were not allowed. However, reader Hunt sent in that they are now able to add their INK Cash card to Apple Pay. I tried and had success with 2 of 3 Chase business cards.
On the official list, it still does not show Chase business credit cards as eligible, but it seems to be working now, in practice. YMMV.
Samsung Pay still does not work with Chase business cards. apparently, INK Unlimited seems to be working with Samsung Pay and Google Pay, but not other Chase business cards (?).
