For security reasons your SmartCard will allow you to enter the PIN incorrectly up to five (5) times. If you incorrectly enter the PIN six (6) times, your SmartCard will be temporarily suspended and will not work.
To unblock your SmartCard, you must call Services Australia the SmartCard eIM hotline on 1800 252 604. The block will be removed within minutes and your SmartCard will be ready to use again. The block is removed automatically at midnight, so if you are unable to contact the Customer Service Centre, your SmartCard should work again the next day.
