Overview
The Bonrix 7-Inch Smart Retail Dynamic QR Code USB Portrait Display is a next-generation, customer-facing payment and digital signage hub engineered to streamline retail transactions and boost counter-side engagement. Originally designed to deliver real-time BHIM UPI dynamic QR payments alongside promotional content, this device has now been upgraded with a powerful Bluetooth Low Energy (BLE) Keypad/Keyboard firmware enhancement. Inspired by the proven DQR-222 architecture, this upgrade transforms the 7-inch display into a fully standalone, smartphone-free, and PC-free payment collection terminal, perfectly suited for retailers who operate without billing software or cannot rely on mobile devices at the counter.

🔹 The BLE Keypad Enhancement: Smarter, Faster, Independent
Many retail counters still run on manual billing or face interruptions when smartphones are occupied with calls, apps, or low battery. To solve this, Bonrix has integrated BLE keyboard support directly into the device firmware. Upon power-up, the display automatically pairs with a compatible Bluetooth keyboard (such as the ZEBRONICS K4000MW), enabling merchants to:
- Enter transaction amounts instantly
- Generate exact-amount dynamic UPI QR codes
- Collect payments continuously without touching a phone or PC
- Maintain a dedicated, distraction-free checkout workflow

This enhancement bridges the gap between traditional cash counters and fully digital POS systems, offering an affordable, reliable, and always-ready UPI collection solution.
