With the improvement of people’s quality of life, more and more people choose to eat in restaurants. However, there is often a problem of queuing up to order in restaurants, and some customers may not be good at communicating with the staff. In this case, an online QR code ordering system can effectively solve these problems. This system enables customers to swiftly access interactive digital menus, place orders, and receive real-time updates while ensuring high performance, uncompromised security, and measurable usability. The project aims to solve the problem of multiple people ordering at the same time and real-time order modification, improving the efficiency of restaurant ordering, making every interaction efficient and enjoyable.

Interactive digital menu: Customers can scan the QR code on the dining table to immediately load the restaurant’s dynamic menu. The menu highlights dish images, descriptions, and prices in an intuitive layout. The menu supports multi-language options and displays multimedia content (images, videos, animations) to enhance visual appeal. Leverages customer history and preferences to present real-time popular dish recommendations and special promotions.
Order issuance and management: Users can directly select, modify, and confirm orders through the application. Once an order is placed, it will be immediately forwarded to a dedicated kitchen display system for timely preparation.
Real time order tracking: Both customers and kitchen staff can monitor the progress of each order - from initial receipt to final delivery.
Secure payment processing: Fully integrated with leading payment gateways such as credit/debit cards and mobile wallets, ensuring a secure and simplified checkout experience.
Management and Analysis Dashboard: Managers can access real-time sales trends, order volumes, and customer feedback to facilitate data-driven decision-making. Allows administrators to update menus, manage promotions, and oversee inventory effortlessly.
This system optimizes the dining process and introduces modern interactive elements, transforming daily dining into a more convenient and efficient experience
For the Minimum Feasible Product (MVP), the project will focus on providing core features that create immediate value:
QR code menu search: The function mechanism of scanning the table specific QR code and displaying the corresponding numerical menu.
Basic order issuance: An easy-to-use user interface that allows customers to select products, view shopping carts, and submit orders to the kitchen display system.
Kitchen order display: Kitchen staff view and update the basic dashboard of incoming order status in real-time.
Advanced features—such as comprehensive payment integrations, multi-language support, and in-depth analytics modules—will be reserved for future iterations after validating the core concept with the MVP.
The success of Scan Master hinges on several key quality attributes, each both measurable and testable:
Performance: Digital menus should load and orders process within 500 milliseconds during normal operation. Response times under various simulated loads using automated performance testing.
Reliability: The system must sustain a 99.9% uptime during restaurant operating hours, even when facing bursts of high traffic. Continuous monitoring through uptime tools and chaos testing scenarios that simulate network and hardware failures.
Security: All data exchanges, including transactions and user data, will be protected via end-to-end encryption, with regular vulnerability assessments. Scheduled penetration tests and adherence to industry-standard security protocols.
Usability: The interface should cater to users with varying levels of technical expertise, aiming for an 85% or higher satisfaction rate in user surveys. Usability tests and A/B testing sessions with both customers and restaurant staff.
The project’s quality attributes will be evaluated via a series of structured tests and real-world simulations:
Utilize load testing tools like JMeter or LoadRunner to simulate various levels of user concurrency and network conditions.
Record and analyze metrics such as menu load time, order processing delays, and overall system responsiveness. Ensure that all performance parameters strictly meet the target values (e.g., sub-3-second response on key operations).
Conduct long-duration tests and chaos engineering experiments that simulate unexpected disruptions (e.g., network outages, server failures).
Track system recovery times and measure adherence to the 99.9% uptime standard.
Perform regular code audits, schedule automated vulnerability scans, and partner with third-party security experts for penetration tests.
Track the number and severity of vulnerabilities identified, and time taken for remediation. Achieve zero high-severity security issues and maintain compliance with industry standards at all times.
Organize controlled pilot sessions where target users (customers and restaurant staff) interact with the MVP, followed by structured feedback surveys and observational studies.
Achieve an 85% satisfaction rating or above, supplemented by qualitative feedback on interface intuitiveness and ease of use.
An iterative feedback loop will be established post-evaluation, ensuring that the insights gained directly contribute to system refinement before scaling up further features beyond the MVP.
