ABSTRACT  
The rapid growth of the demand for quick and easy services in schools and universities brought about the  
transferring of the traditional canteen operations to virtual means. The article presents orderly eats, a food  
ordering application, which has been developed in order to facilitate students in their canteen ordering. The app  
lets students check the menu, place orders at any spot, and enter a little info such as their name and faculty and  
pay via a secure UPI QR code-based payment system. Once a payment is completed, the app creates a specific  
order token. This allows students to avoid the long queues and collect their food when it is comfortable for them.  
The backend consists of Firebase Firestore for real-time database and order tracking, while the Android interface  
is built with Java using Android Studio. The canteen personnel is equipped with an admin interface that gets  
new orders, manually verifies payments, and changes order statuses such as Approved and Ready for Pickup.  
These changes are immediately shown in the student's app, which guarantees efficient communication. The  
system that has been presented increases the operational efficiency, lowers the waiting time, decreases the  
number of people at the canteen during peak hours, and improves the user's overall experience. The app was  
built as a mini-project that demonstrates the practical uses of mobile development, cloud database integration,  
and digital payment processes. It has been shown that Namma Canteen can not only modernize the management  
of the canteen to a great extent but also provide a solid ground for the future improvements such as automatic  
payment verification and push notifications.

INTRODUCTION  
Technology has considerably changed the access to and handling of services for various day-to-day tasks. The  
rapid proliferation of smartphones and widespread availability of fast internet are the major factors that mobile  
apps are playing a significant role in modern life for convenience and efficiency in sectors like banking,  
shopping, healthcare, transport, and education. When it comes to other campus services, the canteen remains one  
of the most crowded places on campus where students frequently encounter a variety of issues due to manual  
operations. Lingering lines, slow service, poor order management, and communication breakdown are just some  
of the problems that most educational institutions face between the students and canteen staff. Typically, students  
have to stand in line to pick their items, make the payment, and then wait to get their food. This traditional  
procedure not only robs students of their valuable time but also causes a lot of traffic during break times, leading  
to delays and dissatisfaction. The ever-increasing number of students in colleges makes it all the more inefficient  
and error-prone to manage orders manually. The challenges mentioned above necessitate the need for a modern,  
digitized, and systematic solution that will not only enhance user's convenience but also optimize canteen  
operations. An Orderly Eats Mobile Application comes up with the solution to all these issues and the idea of  
such an application is the first step in this direction. The primary goal of the system is to make food ordering  
very simple. This means, students will be able to order food anytime from anywhere on the campus using a  
smartphone. Not only this, the application will allow students to see the menu items, make selection, watch  
prices, and place the order without going to the canteen. The moment a student orders, the system assigns a token  
number that is uniquely

Once paid, the order is marked as “Paid,” and the canteen admin can verify the transaction from their UPI app.  
This simple workflow of payment will keep away any cash handling, payment confusion, and ultimately speed  
up the process.  
The Admin Module will be exclusively for use by the canteen staff. They will be able to see incoming orders,  
validate payments, accept or reject them and change the order status to ready. This feature will be a great help  
in cutting down the manual workload, preventing the happening of wrong orders and making the operation of  
the canteen more efficient. In addition, the real time updating of data between students and the canteen is made  
possible through Firebase Firestore with no delay. Students will also have visibility on the live status of their  
orders including whether the canteen has already accepted their request and when the food is ready for them to  
collect.  
The Android application is developed on Android Studio in Java thus targeting a large population of students  
using Android phones. Firebase is the supporting technology providing the backend infrastructure for  
authentication, cloud storage, and real-time database synchronization which makes the system scalable and  
reliable. The merging of these technologies results in an efficient mobile solution tailored to the college canteen  
environment. Overall, the Orderly Eats Mobile Application will bring a smarter, digitized, and organized method  
of food ordering to the colleges. It illustrates the practicality of the mobile app development in resolving real-  
world issues within the academic environment.  
As for the application, it will not only enhance the student experience and canteen management by cutting down  
the waiting time, improving communication, and providing safe channels for digital payments, but it will also  
create a project that will satisfy academic demands with real implementation and future expansion as well such  
as automated payment verification, push notifications, and advanced analytics pertaining to canteen operations.  
RELATED WORK  
Several studies have been carried out in the area of digital food ordering systems, smart canteen management,  
and mobile-based service applications with the objective of improving efficiency and reducing manual effort in  
institutional food services.  
Bhattarai et al. proposed a QR-based canteen management system that enables users to place food orders  
digitally, thereby reducing long queues and improving order handling efficiency [1]. Their work demonstrated  
how QR technology can streamline canteen operations; however, it did not emphasize real-time mobile app  
synchronization or integrated cloud-based order tracking.  
Ali et al. designed a web-based food ordering system using QR codes and linear search techniques to  
facilitate easier menu access and order processing [2]. While the system simplified ordering through QR  
integration, it relied mainly on web interfaces and lacked mobile-centric real-time updates and notification  
mechanisms.  
Nikhil et al. developed an Android-based canteen automation system aimed at reducing human errors and  
improving order accuracy [3]. The study highlighted the benefits of mobile applications in automating canteen  
services, but it did not include secure digital payment workflows or real-time database synchronization.  
Menewar et al. introduced a smart canteen and cafeteria management system using RFID technology to  
automate food distribution and user identification [4]. Although effective, the RFID-based approach requires  
additional hardware infrastructure, making it less cost-effective for small or medium-scale institutions.  
Widodo et al. presented a QR-code-based café menu ordering information system, focusing on improving  
customer convenience through digital menus [5]. The system primarily addressed menu browsing and ordering  
but lacked backend real-time order status tracking and integrated payment confirmation.

Pandey et al. proposed a comprehensive web-based canteen food ordering system that improved operational  
efficiency through online ordering mechanisms [6]. Despite its effectiveness, the system was limited by the  
absence of mobile application support and instant real-time notifications.  
Masurkar et al. developed an Android-based canteen ordering system to reduce waiting time and improve  
service speed [7]. However, the system did not incorporate cloud-based real-time synchronization or modern  
digital payment solutions.  
George et al. implemented a React Native-based food ordering application for canteens, enabling cross-  
platform mobile usage [8]. While the application improved accessibility, it lacked integrated payment  
verification and backend scalability features.  
Reddy presented a canteen management system that digitized ordering and billing processes [9]. The system  
improved administrative control but did not support real-time order tracking or instant communication between  
users and canteen staff.  
Fonggo et al. introduced a web-based canteen payment and ordering system, emphasizing online transactions  
and order management [10]. Although functional, the system was web-centric and did not fully leverage mobile  
application advantages.  
Madake et al. developed an online catering system using Firebase, highlighting the benefits of real-time cloud  
database synchronization [11]. Their work demonstrated the effectiveness of Firebase for scalable systems but  
did not integrate QR-based UPI payment mechanisms.  
Galabi et al. proposed a smart restaurant management system that improved order handling and  
administrative efficiency [12]. Similarly, Attar et al. designed a restaurant web application with integrated  
dine-in self-service, enhancing customer autonomy during ordering [13]. Both systems focused on restaurant  
environments rather than institution-specific canteens.  
Othman et al. developed a QR-code-based grocery ordering system, demonstrating how QR technology  
improves ordering convenience [14]. However, the system was not tailored to real-time institutional food  
services.  
More recently, Anwitha et al. proposed a smart canteen system integrating AI, real-time analytics, and  
cashless payments, indicating the future direction of intelligent food service systems [15]. While advanced,  
such systems require higher computational resources and complex analytics infrastructure.  
METHODOLOGY  
The Orderly Eats mobile application was created using a strict methodology that consisted of requirement  
analysis, then system design, implementation, and finally, testing. The objective was to create a digital canteen  
ordering system that is user-friendly, real-time, and efficient and that can be implemented on college campuses.  
The mobile application Orderly Eats was developed with a systematic approach that encompasses the  
requirement analysis, system design, implementation, and testing. The process begins with the identification of  
the main problems in canteen operations, such as long queues, order entry done manually, and lack of  
communication between students and canteen staff. From these issues, we extracted and determined the  
functional requirements for both user and admin modules, among which are user authentication, menu display,  
order placement, payment, token generation, order status management. The system architecture takes a modular  
approach.  
The frontend is implemented in Android Studio with Java, while Firebase Firestore is the cloud-based backend  
providing real-time data synchronization. The students can select food items, provide their details and make  
payment by using a static UPI QR code. The order token is generated once the payment is done and will be saved  
in Firestore. The admin application will keep fetching and watching the incoming orders which makes it possible

for the canteen staff to approve, prepare, or reject them. After that, the admin will update the order status which  
will then be displayed immediately in the The student application process was through Firebase’s real-time  
synchronization features. The implementation part puts the focus on making interfaces that are easy to use,  
connecting Firestore collections, and making the admin panel for fast tracking of orders.  
Moreover, to enhance the reliability of the system and reduce the time it takes to process requests, we  
implemented QR-based payment, token management, and notification modules as part of the system. Eventually,  
the application was subjected to a series of tests to check how well the order flow, real-time synchronization,  
payment confirmation, and system responsiveness worked with different loads.  
This methodical approach guarantees that Orderly eats is functioning properly and hitting its primary target of  
providing a hassle-free and speedy canteen experience forstudents.  
System Workflow  
The workflow of the Orderly Eats app outlines the interactions that would occur among the student user, canteen  
admin, and the backend system. The system is expected to enable seamless order placements, payment  
verification, and real-time updates on order status. Consequently, this workflow will be partitioned into main  
operational stages as described here.  
User Authentication  
The mobile application is opened by the student who then logs in using the credentials that he/she has registered.  
Authentication of the user is taken care of by Firebase Authentication.The student is routed straight to the home  
screen after the login is successful.  
Menu Browsing  
It retrieves data regarding food items that can be eaten from the Firebase Firestore database.  
In the student's point of view, their view contains names of the items, price, availability of the item, and a  
description. The users pick up their wanted items then they add these items to the cart.  
Order Placement  
After the course is chosen the student provides their Name and Branch information. The user validates the order  
and the application creates a distinctive Order ID and Token Number. The order specifics are instantly uploaded  
to the Firestore "Orders" collection.

Payment Process  
The canteen's UPI ID is associated with a static UPI QR code that is displayed on the screen. The student uses  
any UPI app to scan the QR code and make the payment. For security reasons, the payment confirmation number  
is manually checked by the admin. The admin then changes the order status to “Payment Confirmed” post-  
verification.  
Admin Order Management  
The canteen administrator sees every order that comes in via the app's admin interface. The orders are shown in  
real-time under "New Orders." The administrator verifies the payment and lets the order begin its process. The  
order status gets changed to:  
Accepted  
In Progress  
Ready for Pickup  
Real-Time Notifications  
Firebase real-time listeners make it possible for any status change done by the admin to be reflected right away  
in the student's interface.The app alerts the student when:  
An order is accepted Order is under preparation  
Ready for picking up in the store.  
Order Pickup  
As soon as the administrator indicates the order status as “Ready”, the student gets notified through the system.  
The student arrives at the counter and presents his/her Token Number. The canteen staff gives the food and  
completes the order in the database.  
Order Completion & Data Storage  
Completed orders are moved to an archive collection for record- keeping. The transaction details are kept safely  
in Firebase for future reference or audits.

RESULT  
The Orderly Eats application for mobile phones was developed and tested systematically to evaluate its  
performance, reliability, and usability in a college setting. The testing results showed that the system worked  
well in all its main components which were: user authentication, menu browsing, order placement, QR-based  
payment, and real-time order tracking. The application behaved smoothly during the tests, for instance, the order  
information was saved instantly in Firebase Firestore and status updates were reflecting on the student interface  
simultaneously. Each order was assigned a token number immediately for proper management of the queue.  
Hence, the user interface was very easy to use and responsive; the student quickly found the menu items and  
ordered with just a little effort. The trial users gave positive feedback, detailing how the app made greatly the  
reduction of waiting time and the elimination of the inconvenience of being in long queues during peak hours.  
The design features fast screen loading and real-time notifications that improved communication between  
students and canteen staff.  
The payment process through a static UPI QR code was effective. The students securely completed the  
transaction using external UPI apps, and the canteen admin did a manual check to confirm whether the payments  
were successful. Such a solution was practical and reliable as the cashless payment could be deployed effectively  
at campus level.  
The admin module was also able to demonstrate its strengths during testing. The incoming orders were displayed  
in real-time, and there was no need for any manual refresh, therefore, the canteen staff was able to handle the  
order queue in a better way. The administrators easily changed the status of the orders, and the students were  
informed of those changes instantly, which resulted in better coordination and less confusion at the collection  
point.  
All in all, the system brought about visible changes in the canteen operations: no more queues at the entrance,  
faster service, and the communication among the staff and students was improved. The application offered very  
high accuracy and no data loss during the tests, which were conducted with real-time synchronization; thus, it  
was confirmed to be a digital solution for modernizing college canteen management.  
Testing and Validation  
The tests consisted of unit testing, integration testing, and user acceptance testing. Student-level testing  
confirmed the correctness of order placement, payment steps, and token generation. Admin-level testing verified  
that order retrieval and status updates were functioning properly. Real-time synchronization between student and  
admin modules was verified thoroughly. G. Deployment The final application was converted into an APK and  
then it was tested on real Android devices. During the test, the performance, loading time, and UI responsiveness  
were measured in order to make sure that the app would be reliable even during peak usage hours,

CONCLUSION  
The mobile application Orderly Eats solves the problems faced by the old college canteen systems by introducing  
a single platform for placing food orders, getting instant updates on order status, and making payments through  
QR-based UPI. Firebase Firestore was used for backend operations which means there was real-time  
synchronization between the student and admin modules, while the Android-based interface provided quick and  
easy-to-use user experience. System testing proved that the application was capable of handling order placement,  
payment verification, and token generation very efficiently, and therefore, it was able to reduce peak-hour  
congestion and improve canteen workflow significantly.  
This project is a testament to the power of mobile and cloud technologies in bringing about the modernization  
of institutional services. One of the possible future upgrades can be real-time inventory-based menu updates,  
automatic UPI payment verification, push notifications, and AI that predicts demand for better resource  
management, among others. Moreover, the system's capabilities can be enhanced through IoT/RFID-based  
pickup automation and the provision of web-based scalability across multiple campuses. In short, Orderly Eats  
is an example of a scalable and efficient solution for smart canteen management.
