What you want to ask is why the bus can't be swiped with a long police officer's card? There is no connection. "Bus Card" is a card issued by urban public transport system, and "Dragon Police Card" is a credit card issued by Gansu Bank. The data and information of the two cards are not shared and cannot be directly interconnected. If interconnection is to be realized, relevant institutions need to cooperate and negotiate to realize data sharing and information exchange, so that the police card can be swiped.
