Thank you for your response, perhaps my verbatim isn't polished, I'm not tech savvy.
Apple Pay balance/card lives in the wallet app of an iPhone. Two ways to add cash to Apple Pay
1) Redeem apple gift cards
2) Add money from your apple account default credit card (if you have one setup)
(iPhone - settings - payments and subscription)
Essentially it's the card that a person keeps on file with their Apple ID/account. One can purchase apps, and houses their subscriptions which they used their Apple ID account information to subscribe too.
Apple.com sends a receipt once a month or however often billing is set up and or when purchases are made. Apps can vary from, ms 365, youTube, home security camera's, Apple TV, Apple Music, iCloud storage, ChatGpt, games, etc. this is located on an iPhone in setting - payments and subscriptions.
I can assure you Apple does have an Apple Pay card and it can hold a balance of funds. In order to use those fund on a the Apple Pay Card once loaded you must set up a default card in the wallet app.
The wallet app requires a default card to be set up in the wallet app for the Apple Pay Card/Balance to even show up in the wallet app, the default card associated to an Apple account/Apple ID, are not one a the same. You can use the same card (I would imagine) or not (I do not) but they are not automatically linked when you set up one or both functionalities with the iPhone i.e. Wallet app vs. Apple ID account. They are and act as two distinctly separate functions and therefore must be set up for each.
The only way one can use their Apple Pay balance, at least that I know of:
1) online apple stores
2) Apple Pay merchant machines (not all retailers support Apple Pay).
Which leads back to my original question put forth to the Apple Community
When you have funds on your Apple Pay card in your wallet on an iPhone, can some or all of the balance be transferred to the default card in your wallet i.e. bank or credit card? Or can the funds be transferred back to the card registered to ones Apple ID account?
Any insight is helpful, Thank you in advance
Happy Holidays !!
