HW-1570S Mini OEM Embedded 1D 2D QR Barcode Scanner Module
Mini Barcode Reader Module for QR Code Payment Integration
Designed for next-generation payment terminals and self-service machines, the HW-1570S delivers reliable barcode scanning in a miniaturized package. Measuring L48 x W42 x H15.5mm, this tiny scan engine is built for systems with tight mounting constraints. It connects via an 11-pin 1.25mm interface, offering both USB and serial communication options along with five additional GPIO pins for expanded functionality—all without requiring hardware redesign.
Key Advantages
- Reads both paper and screen-displayed 1D and 2D barcodes with high accuracy
- Supports USB, USB COM, TTL, RS232, and RS485 for flexible system integration
- Operates in auto-trigger, continuous, or host-controlled modes
- Extremely small footprint maximizes design flexibility
- Fully customizable—hardware, firmware, cables, and connectors available
