Mini OEM POS Barcode Integration Screen QR Code Reader
The HW-1570S is an ultra-compact barcode scanner module designed for space-constrained self-service kiosks and embedded payment terminals. With dimensions of just 48mm x 42mm x 15.5mm, it fits seamlessly into small-form-factor devices where installation space is limited.
Compact Design for Embedded Payment Systems
Ideal for QR code payment scanning from mobile screens, this module features an 11-pin 1.25mm pitch connector that supports 5V DC power, grounding, USB, and serial interfaces. Five additional I/O pins are reserved for secondary development, enabling hardware-level customization without circuit modifications.
