Elevate your retail, catering, or service business with the GS-A4 Complete Set Touch Screen POS Machine from GSAN—a trusted leader in POS hardware since 2002. Designed for speed, durability, and versatility, this all-in-one terminal combines a responsive touchscreen, powerful performance, and flexible connectivity to streamline transactions, reduce wait times, and boost overall efficiency. Whether you run a café, supermarket, or boutique, the GS-A4 adapts to your needs with customizable features and reliable functionality.







The GS-A4 is engineered to handle daily business demands with intuitive tools that make cash handling, inventory tracking, and customer interactions smoother:
15.6” True-Flat Capacitive Touch Screen: Offers multi-point touch support for fast, accurate input—no more fumbling with keyboards. The industrial-grade panel ensures scratch resistance, while its 1366×768 resolution and 400nits brightness deliver clear visuals even in bright, busy environments (e.g., sunlit cafes or crowded supermarkets).
Powerful & Customizable Performance: Choose from Intel core i3/i5 processors paired with DDRIII 4G/8G memory and 32G/64G/128G SSD storage. This setup handles multitasking effortlessly, from processing payments to running inventory management software without lag.
Versatile Barcode Scanning Compatibility: Works seamlessly with GSAN’s 1D/2D barcode scanners (sold separately), supporting all mainstream barcode types—including Code39, Code128, EAN-13, UPCA, PDF417, Data Matrix, and Micro QR. Scan barcodes from paper labels or mobile screens (e.g., customer phone receipts) for flexible checkout.
Expandable Peripheral Support: Connect to essential POS devices via its rich I/O ports: thermal printers, cash drawers (like GSAN’s GS-4042), customer displays, and POS keyboards. Ideal for businesses that need a full, integrated checkout system.
Customizable Software & Branding: Preloaded with compatibility for Windows 7/POS Ready7/Windows 8.1/Windows 10—works with most POS software (e.g., inventory trackers, loyalty programs). Add your business logo to the booting screen or customize packaging for a branded look.
