Credit cards have a fixed amount and a withdrawal amount, and the withdrawal amount is configured according to 50% of the credit card amount. For example, if the credit card limit of the landlord is 20,000 yuan, then the cash withdrawal limit is 10000 yuan. The landlord can use the mobile phone number you reserved at his home to edit the short message: "Last four digits of 3 13# card number" to 95533 to check the available withdrawal amount of this card.

In addition, the bank stipulates that credit card overdraft can be cashed up to 2000 yuan per card every day.

Finally, remind the landlord that in addition to the cash withdrawal fee (0.5% of the cash withdrawal amount, at least 2 yuan), interest of 0.5 ‰ of the cash withdrawal amount will be charged every day from the date of cash withdrawal, with a maximum of 2,000 yuan per card per day, and the accumulated cash withdrawal will not exceed half of the credit card limit.

For example, the landlord withdraws 2000 yuan from the ATM of CCB and pays it back after 10.

Total amount payable = withdrawal principal+withdrawal handling fee+withdrawal interest.

= 2000+2000 * 0.5%+2000 * 0.05% *10 (10 interest)

=2000+ 10+ 10

=2020 yuan

As short as 10 days, the extra cost of 20 yuan will be generated, which is actually quite high. It is suggested that the landlord try not to overdraw cash, or pay it back as soon as possible after withdrawing it.
