Abstract
An improvement in manual bar code readers to improve the reliability and eliminate read errors. The improvement comprises a plurality of sensors in a single unit arranged such that a single manual scan results in multiple reads of the bar code. The results of the reads are then compared bit-wise and any read error in any bit is corrected via a bitwise majority voting scheme.
