Q: Apple Pay and Chase Ink Credit Card?

Ask Chase.

When Chase and/or Apple decides. That's when.

Apple has nothing to do with it.   They've made the option available; its up to the Bank and or Credit Card issuer to implement and support it.

In this case only Chase would know when they are going to support it.

But the bank has to negotiate service fee with Apple....? In the end they can accept it or leave it... That's why I put the and/or in my response.

Chase was one of the day 1 launch issuers, so they have an agreement with Apple  So it's on Chase to enable Apple Pay for the Ink credit cards.

it seems

Chase + Visa + apple = all good

Chase + Mastercard +apple = Not good (unexplained reasons)

..But I have Chase Ink Visa Signature and it still does not work!!!!

Been this way since Apple Pay went live.  Annoying.
