If you have instructed us to enable BSTL AutoPay for automatic repayments, you won’t be charged any interest proving that you have adequate eligible assets in your card account for repayments. Otherwise, for ATM tractions, interest is charged immediately. For purchase tractions, your card account will not be debited until the merchant has presented your card traction to us requesting payment. We will send you a notification, through the portal or by email, on the day purchase traction(s) are debited.
