Does Apple Pay setup with camera support portrait mode credit cards?

Question

I have a credit card that the front face is in portrait mode instead of the traditional landscape view. I tried to used the camera to setup this card in Apple Pay but it would recognize it. I had to set it up manually so I could use that card. I was wandering if Apple Pay camera setup is compatible with those types of cards.

WiseJD, that's a good way to test the theory, I agree.  But I'm not really blocked on doing anything here, this is more about technical curiosity.  So I don't plan to try that test, since signing out of iCloud means iCloud photos and docs get deleted from the phone and I'd have to get them downloaded again later.  The hassle exceeds my level of curiosity. 
However, a co-worker pointed me to the iOS Security Guide (Apple Pay starts on page 24).  The second paragraph on page 27 says, "This allows iOS to instruct the Secure Enclave to render cards unusable by marking its copy of the AR as invalid under the following scenarios:
When the passcode is disabled
The user logs out of iCloud
So there is some connection to one's iCloud Apple ID.  The connection appears to be quite minimal, but I accept this as sufficient circumstantial evidence that for users with two Apple IDs, one iCloud and one iTunes, the iCloud Apple ID is the one Apple Pay looks at when deciding whether to offer to include your existing credit cards.
I'll stick with that as my theory unless someone presents a counterexample.  That is, if someone says they use separate Apple IDs on their phone for iCloud and iTunes, they have no credit card in the iCloud account, and Apple Pay *does* offer them the chance to, "Use Card on File with iTunes," (from their iTunes Apple ID).
Thanks.
