lists containing multiple barcodes and manufacturing or transport labels containing more than one barcode
type (either 1D or 2D).
Digital Camera
The device with an integrated camera based barcode scanning solution has the following features:
• Omnidirectional reading of a variety of barcode symbologies, including the most popular linear, postal, QR,
PDF417, and 2D matrix code types.
• Cross-hair reticle for easy point-and-shoot operation.
• Picklist mode to decode a particular barcode from many in the field of view.
The solution uses the advanced camera technology to take a digital picture of a barcode, and executes
state-of-the-art software decoding algorithms to extract the data from the image.
Scanning Considerations
Typically, scanning is a simple matter of aim, scan, and decode, with a few quick trial efforts to master it.
However, consider the following to optimize scanning performance:
• Range: Scanners decode best over a particular working range — minimum and maximum distances from
the barcode. This range varies according to barcode density and scanning device optics. Scan within range
for quick and constant decodes; scanning too close or too far away prevents decodes. Move the scanner
closer and further away to find the right working range for the barcodes being scanned.
• Angle: Scanning angle is important for quick decodes. When laser beams reflect directly back into the
scanner from the barcode, this specular reflection can blind the scanner. To avoid this, scan the barcode so
that the beam does not bounce directly back. Do not scan at too sharp an angle; the scanner needs to
collect scattered reflections from the scan to make a successful decode. Practice quickly shows what
tolerances to work within.
• Hold the device farther away for larger symbols.
• Move the device closer for symbols with bars that are close together.
NOTE: Scanning procedures depend on the app and device configuration. An app may use different scanning
procedures from the one listed above.
