My smart card is going to expire soon. How can I renew it?

The expiry date of your smart card is printed on the card next to your name. You can renew your card online up to 60 days prior to the expiry date. Your  new smart card will be sent to your current address via the DHL courier service. Thereafter, a new PIN code will be dispatched via standard post.
