Method and apparatus for the transfer of sensitive card data over an unsecure computer network
First Claim
1. An apparatus for the secure transmission of card data over a computer network, adapted for connecting to a network device, comprising in combination:
- a card reader including a card reader input for receiving data obtained from scanning a card, and a card reader output for sending data obtained from scanning a card, wherein scanned card data on the card reader are not readable by the network device;
an encryption circuit configured for encrypting card data, including an encryption input connected to the card reader output and an encryption output;
a data interface including a data interface input connected to the encryption output and a data interface output; and
a communications device including a communications device input connected to the data interface output and a communications device output connected to the computer network.

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.
