Hello, each bank has only one credit card center, which is the credit card center of the head office.

Of course, the branches of the card center of the head office also have their own marketing centers. In every city, there are generally credit card marketing centers of branches, which are always under the management of the credit card center of the head office. A bank has only one headquarters credit card center.

Every bank is independent, and it is impossible to serve other banks' cards.

This is a very common sense concept.

And now each bank has two independent card centers, one is a debit card center and the other is a credit card center, which is independent of telephone numbers and service items.
