Do you want to ask what type of bank card needs to be bound to the Google Maps API? The bank card type that needs to be bound to the Google Maps API supports Visa credit cards. Google Maps API refers to the Google Store. The Google Store does not yet support domestic payment cards and UnionPay cards. The international credit card visa can be used to bind the registration, so the bank card type that the Google Maps API needs to be bound to supports visa credit cards.
