You should deposit the specified repayment amount into the designated account for prepayment before the business hours of Sumitomo Mitsui Credit Card Company on the 26th morning of each month. This designated account does not necessarily belong to sumitomo mitsui banking corporation, but other banks can. You should explain it when you apply for a credit card.

It should be noted that it must be before the opening time of Sumitomo Mitsui Credit Card Company. Because, according to the contract between each bank and credit card company, the time of repayment date is different. Sometimes, as soon as the credit card company opens the door in the morning, the computer has already started running.
