The quota of the secondary card is shared with the primary card. If the credit limit of the primary card increases, the credit limit of the secondary card will also increase. The credit limit of the secondary card cannot exceed the credit limit of the primary card. The cardholder of the primary card can limit the amount of the secondary card. If the credit limit of the main card is 50,000, the credit limit of the secondary card can be set to 5000, which can not only satisfy the use of the secondary card holders, but also limit the credit limit to prevent abuse.

The main card and the supplementary card enjoy the same credit limit. If the main card has consumed the credit card limit, the supplementary card cannot consume it, and the accumulated credit card limit of the two cards shall not exceed the maximum credit limit of the card. In addition to sharing the quota, the main card and the auxiliary card can basically be regarded as two independent cards. After the loss of the primary card is reported, the use of the secondary card is not affected, and vice versa.

A bank's credit cards of the same brand share the same credit limit (usually the highest credit limit of a card). Although several cards have their own credit limits, the total overdraft in use cannot exceed the shared credit limit of the brand credit card. The amount of the primary card and the secondary card is the same. If your credit card has a limit of 50 thousand yuan. Today, the main card swipes 40,000 yuan, up and down 1 10,000 yuan, and the auxiliary card can also add up to 1 10,000 yuan. If you change the 50,000 yuan of the main card into a credit card. There is no limit on the consumption of the secondary card, and the balance of the card is insufficient.

"Double 1 1 money is not enough? Double the quota, crazy! " When consumers receive such short messages, their first reaction is often surprise and vigilance. In fact, this is not fraudulent information, but a real credit card marketing activity launched by many banks.

At present, China's consumer finance has entered a high-speed development stage, and credit card, a traditional consumer credit channel, is welcoming a rapidly changing competitive pattern-the internal competition of "personal consumer credit loans" in the banking system is fierce, and external "opponents" represented by Ant Flower Bank and JD.COM White Bar are also gaining momentum with the advantages of online consumption scenes and payment channels.

This competitive situation is particularly prominent in this year's "double 1 1", so credit cards have also become "very hard": for example, increase the temporary credit limit of cardholders, and if cardholders actually spend during this period, convert the consumption amount into a permanent credit limit according to a certain proportion; Another example is the introduction of credit card-bound third-party payment consumption reduction and exemption concessions to increase the application frequency of online payment.

China Economic Net-Credit Card ushered in a new pattern of competition.
