Abstract: An apparatus and method for the secure transmission of credit card data over an Internet connection. The apparatus includes a card reader for reading credit card data and is adapted for connecting to a network device, such as a personal computer. The card data are encrypted in an encryption circuit and transmitted over an Internet connection. The network device is unable to read the card data and so programs running on the network device cannot surreptitiously record the card data and later transmit it to a data thief. The isolation of the network device and the card reader provides for the secure and direct transmission of card data to the intended electronic merchant.
