Track fueling, display the transaction amount, enable QR-based payments, and receive payment confirmation through one integrated embedded solution.
The system is designed around the actual fueling journey, making the payment process easier for both customers and fuel-station operators. Trace the complete transaction cycle below.
The terminal remains in a secure IDLE state until a fueling transaction begins. The instant a dispenser nozzle is lifted, the dispenser communicates with the terminal to initialize the billing session.
During the fueling process, the system queries transaction metrics in real-time, displaying fuel amount and volume directly on the customer-facing terminal display for complete purchase visibility.
Once fueling completes and the dispenser nozzle is replaced, the terminal locks the final calculated parameters. The dispenser submits the finalized price payload to the local processor.
The terminal compiles the locked amount and generates a unique, transaction-specific dynamic QR code. It renders this directly on the screen, ready to accept scan commands.
The customer uses their preferred payment application (Google Pay, PhonePe, Paytm, or BHIM UPI) to scan the display QR code. No manual amount entry is required, eliminating operator error.
The local LDQR application polls the configured bank acquiring APIs to fetch the real-time transaction state. It evaluates the network status return callback secure token.
Upon receiving a successful bank status payload, the customer-facing terminal flashes a success screen. The transaction closes out and the dispenser resets for the next driver.

Our LDQR solution brings together the three critical elements of a modern fuel-station payment workflow to secure transaction integrity.
Establishes physical integration with dispenser control boards over serial networks using industrial RS485 communication protocols. Relays real-time raw pulse metrics, transaction statuses, and dispenser states to the processing unit.
The central computing node powered by an embedded Linux platform running proprietary transaction orchestration software. It processes dispenser logs, coordinates payment payloads, renders high-brightness display outputs, and manages user state flows.
Communicates directly with financial merchant banking networks, acquiring bank servers, or payment gateways through secure low-latency API call structures. This layer resolves authorization state checks (Success, Failed, Pending) and pushes real-time callbacks to Layer 2.
The customer-facing payment unit that sits between the petrol-pump transaction dispenser and digital UPI checkout apps, packed with robust industrial-grade features.
Industrial processing unit built to run continuous service loop scripts, interface local drivers, and handle forecourt network noise.
Dedicated processing script that tracks dispenser statuses, controls screen updates, and handles secure payment payloads.
High-brightness outdoor display, legible in direct sunlight, providing a guided interactive walkthrough for consumers.
Industrial serial standard ensuring consistent, noise-tolerant communication with major dispenser fuel pump protocols.
