There will be no restrictions in the process of transfer and transaction, and you can also purchase wealth management products, pay fees, withdraw cash and other businesses. Usually, the first card a user handles in a bank is a card. The second-class card is an account to meet daily expenses, which is similar to the first-class card in many business aspects. However, in terms of transactions, banks have made restrictions. The daily transfer limit of Class II cards is 20,000 yuan, and the annual cumulative limit is 200,000 yuan.
