There are many types of barcode scanners. According to the scanning code system: one-dimensional barcode scanner, two-dimensional barcode scanner. According to the light source or analysis method: laser barcode scanner, CCD barcode scanner, image scanner. Generally speaking, one-dimensional barcode scanners can only scan one-dimensional barcodes, while two-dimensional barcode scanners can scan one-dimensional and two-dimensional barcodes. As an automatic identification technology product, the two-dimensional barcode scanner can not only read two-dimensional codes, but also support the scanning of one-dimensional barcodes. It usually supports multiple interface standards, such as standard serial TTL or RS232, USB interface, etc., and can be seamlessly connected with various terminal devices such as various POS systems, self-service equipment, handheld devices and access control gates5.
Retail industry: QR code scanners can scan product information, such as production date, shelf life, batch number, etc., which helps to improve sales efficiency and inventory management.
Logistics and supply chain management: QR code scanners can store detailed information about goods, including source, destination, and status, which helps to achieve rapid sorting and full tracking of goods.
Document and identity recognition: QR code scanners can be used to scan and store personal identity information, such as passports, ID cards, driver's licenses, etc., to improve the accuracy and efficiency of identity verification.
Healthcare: QR code scanners can be used to scan and store patient information and quickly access it, such as medical records, test results, and drug information, which helps to improve the quality and safety of medical services.
Financial services: QR code scanners can be used for bank transfers, bill verification, customer identity recognition, etc., to improve the security and convenience of financial transactions.
Education and training: QR code scanners can be used to scan student information management, test score records, teaching materials management, etc., which helps to achieve the digitization and efficient use of educational resources.
The application of two-dimensional barcodes is not limited to the above-mentioned fields. With the continuous development and innovation of technology, its application scenarios will become more extensive and in-depth.
