From the picture shown in the article attached to the OP's post, it looks like the wristbands are similar to a watch. If you don't like it touching your skin or you don't want tan lines, attach it to your belt loop, backpack, purse strap, etc.
I personally feel that these will be easier to keep track of than the card. It's a bit of a pain to keep pulling it out and putting it away. I dislike the lanyards and I've read plenty of people say that the card holders for the lanyards can be unreliable.
