Details
The RK35 is a 1.3MP high-performance 2D scanning engine designed for embedded integration. Built with RAKINDAB’s third-generation decoding algorithm and a 1280×1080 image sensor, it supports 120fps high-speed image sampling and reads almost all universal 1D and 2D barcodes. It performs excellently on low-contrast, stained, distorted and damaged codes, ensuring stable scanning in complex environments.
This ultra-compact embedded barcode scan module uses an all-in-one design that integrates the image sensor and decoder board, with dimensions of only 28.6×20.7×12.5mm and a weight of about 6g, making it easy to fit into various smart devices. It offers HD and SR versions to meet different depth of field (DOF) requirements, with cross-aiming or point-aiming options.
Equipped with USB, RS-232 and virtual COM port interfaces, the RK35 embedded scan engine supports wide voltage and temperature adaptation, strong anti-vibration capability and high ambient light resistance up to 100,000 Lux. It is widely used in self-service kiosks, ATMs, VTMs, smart storage cabinets, queuing machines and certificate-making equipment, providing reliable scanning solutions for retail, banking, e-commerce and smart home scenarios.
