D. Responsible Borrowing
In order to facilitate cardholders to properly consider their card borrowing
and repayment arrangement, thus supporting their financial well-being,
banks should enhance transparency by illustrating the financial implications of different card repayment practices. Banks should also in advance notify cardholders who use over-the-limit facilities when their card spending approaches the credit limits. In addition, banks should issue reminders to cardholders who have signs of developing into persistent debt reminding them to improve their repayments and providing them with possible financial options to deal with their borrowing situations.
