there are two kinds of materials needed for credit card activation: the first kind, if the user goes to the bank counter to activate the credit card, the materials to be provided are the ID card and the copy of the front and back of the credit card. Second, if the user activates the credit card through other channels, there is no need to submit any materials. Credit card, also called debit card, is a credit certificate issued by commercial banks or credit card companies to qualified consumers.

the earliest credit cards appeared at the end of 19th century. In the 198s, the British clothing industry developed the so-called credit card, and the tourism and business sectors also followed this trend. However, at that time, the card could only be used for short-term commercial credit, and the money still had to be paid as needed, and there was no long-term default and no credit line.

Credit cards are generally special plastic cards with a length of 85.6mm, a width of 53.98mm and a thickness of 1mm. The name of the card issuer, expiration date, number, cardholder's name and other contents are printed on the front, and there are chips, magnetic strips and signature strips on the back. Cardholders can use their credit cards to shop, spend money and deposit and withdraw cash from banks.

China's credit card market is still one of the fastest growing product lines in China's personal financial services market. Although the economic benefits of the industry are full of challenges, the average annual growth rate of credit card issuance in China will remain at around 14% in the next 1 years, and the profitability will also tend to improve. It is estimated that the cumulative number of credit cards issued in China will exceed 8 million by 22.
