Shopping online with a credit card can improve the activity of the card. Credit card activity refers to the frequency and amount of credit card use by cardholders within a certain period of time. When cardholders shop online, they not only increase the frequency of using credit cards, but also increase the consumption amount of credit cards, thus improving the activity of credit cards. For cardholders, through online shopping, they can get benefits such as points and cash back, and at the same time, they can increase the use record of credit cards, which is helpful to improve their personal credit rating.
