The upper limit of the credit card amount is less than the lower limit of the amount, which means that when using a credit card for transactions, the transaction amount exceeds the specified upper limit or is lower than the specified lower limit.

When the upper limit of the credit card amount is less than the lower limit, the bank or financial institution will refuse or suspend the transaction to protect the legitimate rights and interests of both parties to the transaction and reduce risks. For example, if the credit card company stipulates that the maximum amount of each transaction is 10,000 yuan, and your transaction amount exceeds this amount, it will prompt "Transaction amount exceeded." At this time, you need to choose another payment method or pay in installments. In addition, some investment funds may set a minimum purchase amount, assuming that each investment must not be less than 1,000 yuan. If your investment amount is lower than this lower limit, the system will prompt "The minimum transaction amount has not been reached."
