Hi team, just a few general questions about Apple Pay:

If user removes card from wallet, then re-adds it, will it preserve its Merchant Token (MPAN) or will a new one be generated?
Is the DPAN the same as applicationPrimaryAccountNumber in this page: https://developer.apple.com/documentation/passkit_apple_pay_and_wallet/apple_pay/payment_token_format_reference
Can a user have the same card active simultaneously in two devices?

Thank you

Yes, it is preserved. This is the main use case for MPANs.

Then, you wrote:

Correct. Although the applicationPrimaryAccountNumber key in the payment token could be either the DPAN or the MPAN, so please be aware of that.

Lastly, you wrote:

Yes, you can provision the same card on multiple devices, and on multiple accounts.

@DTS Engineer thank you for the answers. Very good to know applicationPrimaryAccountNumber could be either DPAN or MPAN. Is this documented somewhere?

(For some reason we thought that the merchantTokenIdentifier was the same as the MPAN. Are they not the same thing?)

It is not documented today, but I've filed an internal bug to get these expectations published in our documentation (r.138777404).

The merchantTokenIdentifier and the merchant primacy account number (MPAN) are distinct values used for different purposes. The former is the opaque, unique identifier for the merchant token and is provided within the encrypted payment token for merchant token payments and merchant token event responses.

The latter is the primary account number for the merchant, which is also known as the merchant token (not to be confused with the merchant token identifier), you can learn more about merchant tokens below:
