but doha bank click card says that the card will be functional in any website uses visa which was mentioned here
http://www.dohabank.com.qa/1/db2/en/Personal/Cards/ClickCard.aspx

and amazon supports visa (check out this card)
http://www.amazon.com/gp/help/customer/display.html?nodeId=513058

so click card will be accepted by amazon ?
please tell me if you are using this card or similar cards that you used to buy from amazon

thanks in advance !
