How do you see the full Apple Pay card number, this article doesn’t work, does it for you?

For security purposes the entire number is not disclosed, only the last 4 digits are available to the card holder and the merchant. The entire encrypted number is stored in the Secure Enclave on your device. Only your bank has the key to decode the entire number. The bank will not share the key to the account holder, the merchant or Apple.

The only number that is fully shown, is the virtual number, as described in the article you referred to above. The mag stripe number and Apple Pay number are both hidden except for last 4 digits.
