Royal Bank of Canada has issued an affinity card with the World Wildlife Fund and Visa logos.

The card comes in classic, gold, and "gold preferred" versions, and a percentage of transactions is donated to the World Wildlife Fund.

The classic and gold cards have no annual fee. Gold preferred costs $110 a year and offers special perks such as a rewards program and out-of- country emergency medical insurance.

The cards "will become an important element to supplement our fund- raising mix," said Dick Barr, chief operating officer of the fund.
