1. The so-called "line sharing" means that all credit cards held by the same cardholder use a common line. A person applying for multiple credit cards in the same bank will not increase the amount. For example, if you hold five credit cards from a bank with a credit line of 10000 yuan, then these five credit cards share the credit line of 10000 yuan. When you overdraw 2000 yuan with one card, you can also overdraw 8000 yuan with the other four cards. Many people apply for multiple credit cards in the same bank in order to pursue the level and rights of credit cards. They may get a cheap plane, or they may get a free trailer, or they may take a better view of a new credit card instead of activating it to collect it.
2. The credit limit is the credit limit of the card given to you by the bank. If this card is dual currency, it will be converted according to the exchange rate. There are multiple credit cards in the same bank. Your credit limit in the bank refers to the one with the highest credit limit, not the sum of all the cards. For example, if you have two bank credit cards, one with a limit of 3W and the other with a limit of 2W, then the credit line granted by the bank is actually 3W, not 3W+2w. Many people have misunderstandings about this problem.
3. It is necessary to activate the credit card. If it is for collection, ordinary credit cards don't need to be activated, because there is no annual fee under normal circumstances. If it is a more advanced credit card, there will be an annual fee if it is not activated. Activation and handling are two businesses with different purposes. In fact, the main purpose of going to the bank to activate is to sign in person. Although I went to the bank when I applied for my first credit card, the bank can't guarantee that every card is handled by myself. Maybe the customer's ID card was lost, or maybe a website leaked the customer's personal information and took it to get a card. Therefore, for security reasons, the bank requires the applicant to sign in person, take photos and stay at the counter again, and the applicant becomes a cardholder. Be careful when handling credit cards. A bank can handle a card. It is not recommended to have more than four credit cards under your name, otherwise it will be difficult to manage.
