For businesses with high transaction volumes or those who prefer a fixed, fast solution, you can use a USB QR reader connected directly to your computer. These devices work like a keyboard: when they scan a QR code, they automatically type the content into the active field.
How it works
Connect the USB QR reader to your computer (plug and play, no installation required).
Open the Welcome Back scanner web app in your browser.
Click on the scan input field so it's active.
Point the USB reader at the customer's wallet QR code and scan.
The system reads the code and loads the customer profile automatically.
Recommended setup
USB QR readers work best for counter or cashier setups where the screen is fixed and staff don't need to move around. Any standard HID-compatible USB barcode/QR scanner works — no special model required. Make sure the scanner is configured to add an Enter key after reading to auto-confirm the scan.
Phone vs. USB scanner
For mobile staff or table service, the phone camera is more practical. For high-volume checkout counters, a USB reader speeds up the process and reduces errors.
