The customer's savings account screen shows their daily interest accrual in real time — not just the monthly credit. Customers see "You've earned NZD 0.63 today at 4.8% p.a." updating every day. This transparency reinforces savings behaviour: customers who can see their interest accumulating daily maintain higher average balances than those who only see a monthly credit. The daily accrual calculator posts the display figure to the customer record nightly.
