Upgradable 2D scanning platform Sweeping a QR code/screen can be scanned/plug and play, using high-frequency LED soft light technology, soft fill light to reduce irritation and damage to human eyes, using high frame rate CMOS sensor and customized lens with excellent image algorithm , can quickly identify all kinds of barcodes, using Youku's independent image algorithm and after years of iterative optimization, it can smoothly identify various color, high-reflective, punched, deformed, and blurred barcodes while taking into account high-brightness and low-brightness mobile phone screen barcodes. Online upgrade and iteration, and R&D support that cannot read barcodes only needs to update the firmware, which completely solves the worries of customers. The shape of the head with four chamfered corners and the round base make the product shape unique and simple; break through the heavy and dull impression of the general scanning platform. From the selection of the main chip, sensor and lighting to the circuit design, all have been specially made. The low power consumption processing takes into account the excellent scanning performance, and also ensures the reliability of data transmission under various power supply conditions.
