The TigerEYES Master—Minder™ Bar Code Mix Detection System is designed to assist operators in comparing an original or Master Bar Code to one or more Product or Item Bar Codes. The Utility runs in a Portable Bar Code Reader or PDA. The program operation is displayed visually on the PDA screen and signaled audibly through tones emitted by the PDA. Errors are signaled visually, audibly and by optional vibration until the error is reset.

In the simplest case the operator scans a Master Bar Code and then scans a single Product or Item Bar Code.  For example, this operation mode supports the comparison of a shipping document to a shipping label. Or the operator may be comparing a Bar Code on a Sales Order to a Bar Code on a Pack List or physical Item.

Audible tones signal that the Master Bar Code has been accepted. A different audible tone then signals that the two Bar Codes match and then the Master Bar Code is reset ready for the next comparison.  There is no need to touch anything on the PDA screen. The operator can identify what is happening by the unique audible tones from the software. Errors are signaled visually, audibly and by vibration until the error is reset.

The TigerEYES Master—Minder™ Bar Code Mix Detection System can also be used to compare one Master Bar Code to either a fixed or an unlimited count of Product or Item Bar Codes. Press the Setup  button to change the expected Item Scan Count. When more than one Product or Item is expected, the PDA screen then shows the count of Products or Items as they are scanned and the total number of Products or Items required.

This operating mode is very useful to detect a mix as items are packed for shipment. Just scan the Product or Item Bar Code on a Sales Order or Pack List. Then scan each Product or Item as it is placed into the shipping carton. An audible tone signals that each scan has been completed. A separate distinct tone and vibration warns the operator if an error (or a product mix) is detected.
