Cardless deposits can be made with a credit card, as long as you can transfer money directly to the credit card through an ATM, mobile banking app, etc., and you know the credit card number. However, depositing money on a credit card is usually for repayment. If you want to store spare money, it is not recommended to deposit it in a credit card, because there is no interest on credit card deposits, and there is a handling fee when you withdraw it.
