MDF Best Practices
Suggestions to minimize the undesired multiple outputs during the MDF scanning in hands-free mode are as
follows:
• Scan barcodes in a vertical orientation (see Figure 16-2).

• When creating the MDF programming with multiple groups, the Group 1's pattern match should be the most
complicated (hardest to match), which equals to the most number of barcodes and criteria. Then Group 2, 3,
and so on should be progressively matched more easily.
• When defining criteria, avoid enabling an output when the pattern is not matched. Set Output if NO pattern
match set as Discard bar code (see Figure 16-3).

• Select Discard barcode(s) NOT within the pattern match in the 123Scan MDF setting. For more details,
