Smart barcode readers can be classified according to their working principles and uses. The following are several common types of smart barcode readers and their characteristics:
Laser barcode reader: The laser barcode reader uses a laser beam to scan the barcode, converts the laser beam into a scan line through an oscillating mirror or mirror wheel, and the reflected light is converted into an electrical signal by a photodiode, and finally decodes the barcode information. Laser barcode readers are suitable for high-speed scanning and long-distance reading.
Area array camera barcode reader: The area array camera barcode reader uses an image sensor to capture the barcode image, converts the image into a digital signal, and performs image processing and analysis through a built-in CPU, and finally outputs the barcode information. Area array camera barcode readers are suitable for barcode reading with high precision and complex backgrounds.
Line scan camera barcode reader: The line scan camera barcode reader uses a line array camera to shoot moving objects, converts the photoelectric signal into a digital signal for processing, and is suitable for barcode reading of high-speed moving objects.
Fixed barcode reader: Fixed barcode readers are usually installed in fixed locations, such as desktops or terminal devices, and are suitable for scenarios that require long-term stable operation, such as electronic ticketing, membership systems, etc.
Embedded barcode reader: Embedded barcode readers are integrated into other devices and connected through interfaces such as USB, RS232/TTL, and are suitable for automated equipment and scenarios that require embedded reading functions, such as smart transportation, self-service equipment, etc.
Handheld barcode reader: Handheld barcode readers are portable and easy to operate, and are suitable for scenarios that require frequent scanning, such as supermarket checkout, warehouse management, etc.
