Legal analysis: 1. At present, individuals can check all their credit card status, go to the People's Bank of China and have their own credit records. With their valid identity information, they will provide you with a personal credit report with all the credit card status.

2. There is no particularly good way to check all your savings cards, because the core systems inside commercial banks can't be networked. You can go to the counter of every bank that has handled your own card, or call the bank's customer service phone to check manually. You need to provide your ID number.
