Bar code scanner and method with magnetic and optical readers

摘要

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 extracting of data from the bar code and 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 if complete, data is extracted and if incomplete a complete image formed from the two individual scans. The device also employs a magnetic strip data reader to extract magnetically encoded data.
