May 19, 2022

Which applications requires the 2D scanning module? Perhaps in most people's minds, the barcode recognition technology services around our lives are handheld barcode reading devices, but not at all. In recent years, due to the increasing demand for QR code recognition service applications and the continuous expansion of application fields, QR code scanners have now penetrated into all aspects of our lives. Flexibility, performance, durability, ease of use are mostly concerned by users. More and more industries put forward higher requirements, from mobile payment to self-service terminals, from industry to medical care. Many companies use embedded QR code scanner modules to create branded smart self-services .

For example, self-service equipment can also realize the function of scanning QR code payment by using QR code technology. This is because it is embedded with 1D or 2D barcode scan engine. The QR code recognition performance of the screen is decoded by hardware and combined with chip-level hard encryption to perform real-time and secure data upload operations, read the mobile payment code for scan code verification and upgrade the payment collection function. The QR code scanning module is installed in an embedded way and can be applied to self-service equipment, new and old channel gate equipment, access control terminals, self-service cabinets and various intelligent terminals. From this we know that it has a very high market share and is widely used. For example, the RD4300 2d scanning module launched by RAKINDA is still relatively mainstream in the market.


The QR code scanning module has a wide-angle reading window, and the reading accuracy can reach 5mil. It has excellent screen reading ability, special adjustment and optimization for the screen bar code, can adapt to low brightness and large data volume screen bar code of all kinds of films, and provides TTL232, USB and RS-232 interfaces, buzzer and buttons. Direct communication through the Dupont port connection; compact and popular design, which can be perfectly embedded in various machines, such as VTM cabinets, e-commerce self-pickup cabinets, smart home lockers, ATM self-service cabinets, and self-checking applications such as payment terminals and queuing equipment.
