I have also tried this kind of thing, it turns out that this is the same thing: because the People's Bank of China now generally opens chip cards, so many banks are now replacing the chip card, but the current chip card is not very perfect, so some chip cards will show that the card is invalid in the teller \/IC card chip cannot be used, please contact the card issuing bank. In a similar situation, you can only carry your ID card to replace the chip card.
