Existing EZ Link cards can be exchanged for new ones from Friday (Jan. 9, 2009)...(except childrens starting Feb. 16 and seniors starting April)

Commuters, who are allowed to exchange up to three cards at one time, have until September 30 to do so. They will get a refund of the remaining value in their old cards.

According to LTA, there are about 8 million EZ Link cards in circulation. And unlike the old card, the new EZ Link card will not have a travel deposit, giving commuters full use of the stored value of the card.
