A system and method for providing visual feedback to facilitate multi-code (e.g., barcode) reading (i.e., scanning) is presented. The visual feedback will project a read status for each code scanned. The visual feedback for a particular code will be projected onto that code. For example, an “X” projected onto a code would indicated that this code was not read and needed to be scanned again. This visual feedback minimizes the number of codes that need to be rescanned in the case of a read error.
