First wave of Opus cards set to expire

The first wave of Opus cards sold in April 2008 is going to begin to expire fairly soon, although the article is a bit vague on actual dates. As I understand it, the chip has a limited number of spaces that can be activated, and once these have been used up the card is finished. Item says the cards will be replaced free and more info will be available as of Thursday at http://www.carteopus.info.
