If the cardholder has a single visa card, if there is no demand for the card, he can cancel the visa card at the counter staff of the bank's business outlets.
If the cardholder holds a set of cards, it cannot be cancelled separately. If you want to cancel the visa card, you must cancel the visa card together with the UnionPay card before you can cancel the visa card. If you really don't need a visa card, you can consult the bank credit card customer service in advance, subject to the customer service reply.
