"Traffic Safety Information Card" is a credit card, which can increase the overdraft limit. At present, it is mainly issued by China Construction Bank (with a limit ranging from 1 yuan to 1, yuan) and Industrial and Commercial Bank of China (with a limit ranging from 6 yuan to 5, yuan). The specific rules for increasing the limit have not been clearly announced yet, and the criteria for increasing the limit of this card are significantly higher than those of other cards directly applied through banks. Traffic safety information cards have "financial functions" such as overdraft consumption, special installment payment, high insurance and withholding. When opening the "financial function" of this card, you need to provide property proof materials such as real estate license, otherwise this "credit card" will have no limit, and you will have to deposit money in the card first to pay the fine, but there is no interest on saving money.
