What Makes the A77 Different?

  • Paperless by Design: Instead of relying on a built-in printer, the A77 is designed for digital receipt delivery (SMS/email), so you can reduce time and costs associated with changing and buying new printer rolls.
  • QR-Ready Workflows: The A77 can scan and display QR codes on-screen, ideal for modern checkout experiences and app-driven workflows beyond “just a card sale.”
  • Designed for Fast Training and Adoption: A large touchscreen and familiar Android navigation make the A77 feel natural to teams accustomed to smartphones. The system is helpful when you’re training seasonal staff or rolling out mobile checkout across multiple roles.
  • Built for “Payment + Operations” in One Device: Dual cameras and an optional professional scanner enable the A77 to support scan-intensive tasks (inventory, ticketing, product lookup, delivery confirmation), depending on your HMS-approved app.
  • Connectivity That Keeps You Mobile: With 4G + Wi-Fi (5 GHz) + Bluetooth, the A77 is built for businesses that can’t be tethered to one register.
  • Modern Security Standards: The A77 supports EMV and is designed to meet current payment security requirements (including PCI certifications), helping you reduce risk when processing payments in the field.

Flexible Setups for Everyday Business Use
