What are the QR code scanning devices? Which strong QR code reader?

A QR code scanning device is also called a QR code reader / QR code scanner, and is a core component of a QR code hardware decoding device. The two-dimensional code scanning equipment can automatically scan the one-dimensional two-dimensional bar code information on paper, mobile phones and other media and perform the two-dimensional code decoding and data transmission work. QR code scanning platform. Take the 18 years of automatic identification field, the most researched and developed manufacturer as an example. For these two classifications, what are the QR code scanning devices?

1. Embedded QR code scanner: This type of QR code device is relatively concealed and is generally embedded in the machine of various handheld devices, self-service devices or smart terminals, only the scanning head is exposed to the outside; then through USB, TTL- 232 serial ports and other interfaces are self-sensing or command-triggered and use a certain communication protocol to decode and transfer data to the background system. As a chestnut, the most common barcode scanning self-service vending machine in subway stations. With an embedded QR code scanner, passengers do not need to use cash or coins to buy drinks. Just open the mobile phone Alipay or WeChat payment QR code and swipe it above the scanning window. You can pay successfully. The current mainstream embedded QR code devices are LV3096 / LV3296 / LV3396 (mainly embedded in handheld devices / portable devices), LV4200 / LV4500I / LV4500L / LV4500R / LV4500-20 / LV4600 (mainly embedded in self-service devices / channel gates Machine / intelligent access control / bus code scanning equipment / high-speed and long-distance code scanning equipment and other smart terminals), LV3000U / LV3000R / FM420 / FM430 (mainly embedded in display kiosks / ticketing machines / vending machines, etc.), other OEM embedded two Dimension code scanner.

2. Fixed QR code scanning platform: This type of QR code device is generally placed directly on the desktop as a scan code collection device. Similar to the scanner, it is already packaged with a built-in mobile phone QR code reading engine. When we go to KFC or McDonald's to place a meal, we place the mobile payment code directly on the QR code scanning platform to pay directly, and it is directly connected to the cash register device. The current mainstream models are: RD4100 (mainly used in hotel catering / high-speed toll stations / gas stations / retail as QR code collection equipment and lightning invoicing applications), S-800 (mainly used in collection applications), other two-dimensional Code scanning platform.

In the future, the QR code recognition technology will bring a more intelligent experience to our lives. The value of the manufacturer (RAKINDA) is that through leading QR code equipment and barcode scanning solutions, it aims to provide customers with the industry's most Excellent products and services.
