Abstract
An improved card scanner for imaging and decoding indica such as bar codes on a side surface of an inserted card. The device is electrically powered and features a double scanning method using an electronic imaging element and processor which turns off unnecessary power when not required. This is accomplished through the use of a processor and software to determine if a complete image of the bar code on the inserted card has been captured and allowing immediate removal of the card. Should the image of the bar code be incomplete, a second scan is conducted of the bar code as it is removed and a complete image formed from the two individual scans. The device can also be used to compare photographs scanned from a card with the digital photograph scanned from a two dimensional bar code and to display both photos for viewing.
