Barcode Scanner Reading Preference
The reading preference of a barcode scanner mainly depends on its design, function and application scenario. Here are some key points about the reading preference of a barcode scanner:
Barcode Type: 1D Barcode: Most barcode scanners can easily read standard 1D barcodes, such as UPC, EAN, Code 39, Code 128, etc.
2D Barcode: For 2D barcodes, such as QR Code, Data Matrix, PDF417, etc., the device needs to have the corresponding decoding capability. Some high-end or professional barcode scanners support the reading of multiple 2D barcodes.
Barcode Size: Barcode scanners have certain requirements for the size of the barcode. Generally speaking, the larger the barcode, the easier it is for the scanning device to read. However, with the advancement of technology, modern barcode scanners have been able to read barcodes as small as a few millimeters. For example, XTIOT's XT6201GHD barcode scanner can read 2x2mm metal engraved DPM codes.
Barcode Quality: The clarity and contrast of the barcode have a great impact on the reading ability of the scanning device. The barcode must be clear, with clear contrast, and without damage or stains to be accurately read by the device.
Scanning distance and angle: Different barcode scanners have different scanning distances and angle ranges. For example, laser scanners usually have longer scanning distances and larger scanning angles, while red light scanners are more suitable for close-range and fixed-angle scanning.
Scanning speed: Scanning speed refers to the number of barcodes that the device can read per second. High-speed scanning equipment is suitable for application scenarios that require rapid reading of a large number of barcodes, such as supermarket cashiers, logistics sorting, etc.
Decoding capability: Decoding capability refers to the device's ability to parse barcodes. Some high-end barcode scanners have powerful decoding algorithms and processors that can parse complex barcode structures and improve reading accuracy and speed.
Durability and environmental adaptability: For barcode scanners that need to work in harsh environments, such as warehouses, factories, etc., their durability and environmental adaptability are crucial. These devices usually have functions such as waterproof, dustproof, and drop-proof, and can work stably in various environments.
Special needs: For some special industries or application scenarios, barcode scanners with specific functions may be required. For example, the medical industry may need a device that can read special barcodes on drug packaging; the retail industry may need a barcode scanner that supports multiple payment methods. For example, for MSI drug supervision codes, you can use the XTIOT price checker XT802C/D/E/F series produced by Xingtong, a wall-mounted self-service all-in-one machine with Windows or Android system, supporting WiFi network, LAN network and PoE network power supply.
