1. A method for remotely decoding a bar code for security purposes, comprising:
- sending security information to be displayed as the bar code;
capturing an image of the bar code using a camera;
transmitting the image of the bar code across a network;
receiving the image of the bar code at a remote location on the network;
reproducing the image of the bar code on a video display at the remote location to provide a reproduced image of the bar code;
scanning and decoding the reproduced image of the bar code from the video display using a bar code reader operated by a user to provide information; and
verifyng the information extracted from the reproduced image of the bar code matches the security information.
