The card number I received after replying to the invitation letter of JCB Gold Card of Shanghai Bank is different from the previous constellation card, but how is the usage quota and transaction record the same? First of all, no matter which bank, the credit card limit is enjoyed by * * *, and the total amount will not exceed the credit limit given to you by the bank; For example, if a bank passes the comprehensive score, you can approve a card with a credit limit of 1 000, so no matter how many cards you handle in this bank, the credit limit will not exceed 1 000, and the sum of overdraft amounts of all cards will not exceed 1 000.

As for transaction records, different banks are different, and some banks have different cards that are relatively independent, including points calculated separately; Moreover, some banks are all under the account of the same person according to their ID numbers, and Shanghai Bank may belong to the latter.

The purpose of the bank (guess): 1. In order to complete the task of issuing a certain card; There seems to be no gold card in the constellation card. I'll give you a gold card for you to use more. In order to promote some special functions or preferential measures of jbc Gold Card, such as shopping in Japan, this card may be more convenient. Moreover, this card is free of annual fee, and it is no problem to have one more card. In the final analysis, it is to let you use their cards more, provide convenience in different situations, and keep you as a customer.
