If you are a teacher with national employment, you can apply for a high-limit credit card! The maximum limit of Puka is 50,000 yuan. This is just a legend. Currently, I have a Puka worth 60,000 yuan! Generally speaking, if your credit limit exceeds 10,000, the bank will actively invite you to upgrade to a gold card. If the credit limit exceeds 50,000, the bank will invite you to upgrade to a platinum card user. The limit of a standard platinum card is still relatively high, but There is usually an annual fee of 2,000-3,000 yuan! Of course, the starting limit is 50,000! If you want to apply for a 100,000 card, you need to provide a lot of financial proof, such as real estate, cars, large deposits, etc. in your name! If you continue to use your current credit card and there is no bad record, banks will generally make a permanent limit adjustment for you every six months. You have to call and apply for this after half a year of use!
