I bought this card as I did not want to use my credit card details. It is easy enough to use - you rub off the silver stuff on the card to reveal the code and enter the code on Wii Shop to add the points. Most games appear to cost 1000 points. I bought Monkey Island Chapter 1 with it. The card itself is credit card sized and came with a lot of documentation about it. The price was reasonable compared to some video game shops.
