Called 'Netswipe'. They allow a merchant to download their software, then when you are billing a customer, they simply show their credit card on their webcam for instant credit card verification. If you read their online pitch, they claim to be an internet marketers best friend, due to the instant verification of the customers c/c, so, less fees for the merchant as there's less risk involved.
One of the backers of the company is Eduardo Savarin, the partner who got booted from facebook.
It seems a bit too complicated and early to try and implement for most of us on here IMO (I'm sure many customers will feel uneasy about showing their credit card on webcam), but, this might be one to watch out for.
Watch the video...WAY cool!
