When we use static bar codes, that is, printed QR codes of shops or roadside stalls, we can pay 500 yuan in a single bank account or all payment accounts of the same customer in a single day.

If it is by displaying the dynamic bar code, that is, when the cashier scans his own QR code after buying something:
If the dynamic bar code is verified by two or more effective elements, including digital certificate or electronic signature, then the single-day payment is unlimited and can be independently agreed by the bank or payment institution.
If the dynamic bar code is verified by two or more effective elements, excluding digital certificates and electronic signatures, the daily limit of all payment accounts and fast payment is 5000 yuan.
Also, if there are less than two effective elements for dynamic barcode verification, the daily limit for all payment accounts and express payment is 1 1,000 yuan.

Financial management strategy
1, control the number of credit cards, enough is enough.
Once there are too many credit cards, it is easy to get the repayment date of this card wrong and forget the credit limit of that card, which is difficult to manage, and it is easy to cause overdue repayment and leave a bad record. Moreover, multi-card credit card points, too scattered points are not conducive to redemption of gifts. Therefore, it is suggested that only 1~2 credit card is enough.
2. Keep credit card vouchers
Most credit card holders don't care about these documents, and they won't keep them. Most of them are thrown away, which is a very bad habit. In fact, keeping good credit card vouchers is not only convenient for summarizing consumption records every month, and then analyzing and optimizing consumption habits, but also helpful for improving the rationality and transparency of credit card consumption, so as to clearly understand credit cards. Moreover, many people's credit cards do not have passwords, and discarding credit card vouchers at will may lead to the theft of credit cards.
For safety reasons, it is best to keep credit card vouchers after consumption, so that you can know fairly well and develop good credit card financial habits.
3. Reduce cash withdrawals
Credit cards have two functions: overdraft and cash withdrawal, but cash withdrawal requires a certain percentage of handling fees, and even if you deposit your own money, you have to charge. Therefore, it is not cost-effective to use a credit card to withdraw cash as a passbook.
