1. Billing installment (only for business cards, business cards (including financial business cards), purchase cards, ANA protection cards or supplementary cards): you can enjoy the interest-free period, but there is a handling fee. Handling fee per installment = total installment amount × handling fee rate per installment. The minimum handling fee for each period is 5 yuan, and the benchmark rates for each period are: 0.9% for the third period, 0.75% for the sixth period, 0.70% for 10, 0.66% for 12 and 0.68% for 18 respectively. Then the repayment amount of each installment is 800/6= 133.33 yuan, and the interest of each installment is 800*0.75%=6 yuan) For details, please log on to the credit card website/and click "Credit Management"-"Bill Installment" to inquire; It's really impossible to get cash in installments.

2. Minimum repayment amount: no handling fee but no interest-free period. If the minimum repayment amount is paid before the final repayment date, but less than the full amount, you cannot enjoy the interest-free repayment period. From the bookkeeping date (usually the day after consumption), interest will be charged on all consumption in the current period, with a daily interest rate of 0.5 ‰ until you pay it off in full.
