Then you may be interested in this device, it uses a similar process that stores do when you swipe your card, expect this time the device encrypts your data allowing you to make online purchases without the fear of spyware picking up your details.
You simply plug this device into the USB port and you are good to go.
Features – The included software works with your browser such that when you go to a website and are ready to purchase an item or service, a swipe of your card through the device encrypts your credit card data before it reaches your computer.

Works with Windows XP/Vista/Windows 7 and Internet Explorer 6 or higher (Firefox support is forthcoming). 3″ L x 2″ W x 1 1/2″ H. (6 oz.) Priced at $89.95
