6. Sensory Guide: Understanding the Beeps & Sounds
When you tap your card on the reader, it communicates with you through sounds:
- One Beep (Ding): “Success!” You have been charged the normal adult fare.
- Two Beeps (Ding-Ding): “Discount applied!” This sound confirms your Child or Youth discount is active.
- Multiple Beeps or Alarm: “Error!” Usually means insufficient balance or a tapping error. Check the screen!
