Modern barcode scanners use imaging technology, such as area imagers, to capture images of barcodes. These imagers can capture a wide field of view, allowing them to read multiple barcodes within a single frame. |
3.2. Decoding Algorithms |
Once the image is captured, the scanner’s decoding algorithms process the image to identify and decode each barcode. These algorithms are designed to recognize various barcode symbologies and can handle different orientations and sizes of barcodes. |
3.3. Data Output |
After decoding the barcodes, the scanner outputs the data to the connected system, such as a computer or mobile device. The data can be transmitted via wired or wireless connections, depending on the scanner’s capabilities. |
