Can I addMoney to Apple Pay using bank account

Re: "Can I addMoney to Apple Pay using bank account"

No. Apple Pay itself is not an account that can hold money.

Apple Pay just transfers money using credit and debit cards to pay merchants.

If it can help:

Apple Cash can be set up for sending and receiving money to trusted friends using Messages app.

NB: You must be a resident of the United States and your device must be in the United States.

Seems you also use credit / debit cards that are in Wallet app to add money to Apple Cash.
