Abstract

A low cost, high performance bar code reader is required for reading the CFC-6 character font. The character is printed in fluorescent bars which are coded by different spacing between each bar so that it can be machine readable. A special recognition logic is developed to read the font when it is data lifted by the analog front end. An error correction capability is built in to correct certain correctable errors such as a missing bar.
