Barcode Scanner and Code39
The support of barcode scanner for Code39 can be described and summarized clearly and in points from the following aspects:
1. Overview of Code39
Code39, also known as Code 3 of 9, USD-3 or LOGMARS, is a widely used barcode format. Its characteristics are that it can encode letters, numbers and some special characters, and is easy to generate and recognize. Code39 is divided into standard type (Standard Code 39) and full type (Full ASCII Code 39).
2. Characteristics of Code39
Encoding rules: Each character of Code39 is composed of 5 lines, where thick lines represent 1, thin lines represent 0, and wide gaps between lines represent 1, and narrow gaps represent 0. This encoding method ensures that 3 of the 9-bit binary code must be 1, hence the name Code39.
Character set: Standard Code39 supports 26 uppercase English characters from A-Z, 10 numbers from 0-9, and 8 special symbols such as "+", "-", "*", "/", "%", "$", ".", " " (space), totaling 44 characters.
In addition to standard characters, the full Code39 (Full ASCII Code 39) can be expanded to 128 characters (including 1 start and end character) by matching "/", "%", "$", "+" with prefixes.
Easy to identify: Code39 barcodes are easy to identify with scanning devices, which improves the speed and accuracy of data input.
Strong versatility: Code39 has a wide range of applications in commercial and industrial fields, and can be used to mark goods, track logistics, locate inventory, etc.
High reliability: Code39 code verification rules can ensure the accuracy of barcodes and reduce the possibility of data input errors.
Strong durability: Code39 barcodes have good durability and can be used in various environments, such as printing on paper, labels or products.
3. Barcode scanner support for Code39
Compatibility: Most modern barcode scanners support Code39 scanning and parsing. For example, the wireless 2D barcode scanner XT6400 produced by XTIOT can quickly and accurately capture and parse the information in the Code39 barcode.
No specific configuration required: The XT6400 wireless barcode scanner has built-in support for Code39 when it leaves the factory, and no additional configuration or settings are required.
Multi-platform support: Whether it is the XT6400 wireless handheld scanner, the XT7302P desktop scanning platform or the built-in camera scanning function of the mobile device XT8006, Code39 barcodes can be easily read.
4. Recommendations for using Code39
Choose the right device: Choose the right barcode scanner according to the specific application scenario. For scenarios that require frequent scanning, you can choose a handheld scanner or a mobile device; for fixed-position scanning needs, you can choose a desktop scanning platform.
Ensure barcode quality: In order to obtain better scanning results, you should ensure that the print quality of the Code39 barcode is clear and high in contrast, and avoid contamination or damage to the barcode.
Regular maintenance and updates: Keep the barcode scanner's software and hardware updated to ensure that it can continue to support the latest barcode standards such as Code39.
Training and operation: Train the operators of the barcode scanner to ensure that they are proficient in the use of the equipment and precautions.
