Project Name: Magnify https://youtu.be/hA9bn7KzI30

Requirement: Event organizers need a robust, real-time, and customizable event management platform

Developer: [Helly & Ritesh / Hana Platform Private Limited]

Technologies Used: HANA (SaaS), JSON, Node.js, Express.js, React, QR Code Generation, API

Executive Summary

Magnify is a HANA-powered, event management platform that offers dynamic, JSON-configurable registration, real-time attendee tracking, and secure QR code-based check-in across devices. Built to handle high concurrency and real-time validation, Magnify supports simultaneous QR code scans across multiple devices without performance degradation. HANA’s scalability and rapid data processing enabled the platform to efficiently manage registration caps, dynamic content, and multi-device scanning, all in real-time.

Background and Problem Statement

The client sought a comprehensive solution to streamline large event operations, where real-time updates and flexible registration flows were essential. Key requirements included:

Complex Registration Logic: Dependent dropdowns tailored to specific event branches (e.g., “CCF Main” or “CCF Satellite”), with sections dynamically displayed based on selections.

Real-Time Registration Cap: Automatically stop registration once the limit of 600 attendees is reached, displaying live progress on the dashboard.

Role-Based Access Control: Define access restrictions for Admins and Volunteers, with Volunteers having access solely to scanning modules.
Concurrent, One-Time QR Code Scanning: Ensure secure, single-use QR codes for event entry and lunch, with support for simultaneous scans across multiple devices.

Immediate On-Site Registration: Enable quick, direct registration at the event, allowing Volunteers to generate QR codes on-demand.

HANA’s data processing capabilities made it possible to handle high-concurrency demands, with robust real-time processing that managed all requirements seamlessly.

Project Scope and Objectives

Primary Goals:

Leverage HANA’s Strengths for Dynamic Registration: Enable customized registration with dependent dropdowns via JSON.
Real-Time, Concurrent QR Code Validation: HANA’s scalability and data handling allow secure, multi-device scanning for single-use QR codes without risking duplication.
Real-Time Dashboard for Registration Tracking: Reflect live updates of registrant counts with HANA’s rapid data retrieval.
Role-Based Access Control with HANA: Differentiate access to modules based on user roles, with Volunteers limited to the scanning module.
Flexible On-Site Registration: Allow quick QR code generation for immediate registrant check-in.

Solution Design and Implementation

Technology Stack:

HANA for fast data access, scalability, and real-time API responsiveness.
JSON for flexible registration form configurations.
Node.js and Express.js to handle backend server logic, RESTful APIs, and concurrency.
React for a responsive and intuitive frontend.
QR Code API to generate unique QR codes with single-use validation.

Architecture and Key Features:

Dynamic, JSON-Driven Registration: HANA’s flexibility with JSON allowed configurable dropdowns with interdependent fields, where branch selections triggered specific content displays.
Concurrent QR Code Handling with HANA: Magnify’s API supports high-concurrency QR code scans, allowing multiple devices to validate QR codes simultaneously. Leveraging HANA’s fast transaction processing, QR codes are verified and marked as “used” immediately upon scanning, ensuring no duplicate access while keeping the entry flow seamless.
Real-Time Registration Tracking: HANA’s capabilities allowed the dashboard to reflect real-time registration counts and immediately cap additional registrations once the 600-attendee limit was met.
Role-Based Access Control: Through HANA’s data handling, Admins had full access to all modules, while Volunteers were limited to the Scanner module, ensuring controlled, secure access to sensitive registration data.
On-Site Registration for Immediate Access: Volunteers could generate QR codes on the spot for walk-in registrations, ensuring a quick, seamless process for attendees arriving on-site.

Development Process:

Using an agile approach, each feature was developed iteratively, with HANA enabling fast data handling adjustments and JSON ensuring customizable configurations for each event.

Challenges and Solutions

Handling Multi-Device QR Code Scans Simultaneously: Solution: HANA’s concurrency capabilities allowed for secure, simultaneous QR code validation across multiple devices. By marking QR codes as “used” immediately after scanning, the system prevented reuse and ensured efficient flow at entry points.
Real-Time Updates and Registration Limits: Solution: HANA’s fast data retrieval updated the dashboard instantly with each new registration, enforcing a cap at 600 attendees in real time without delays.
Secure One-Time QR Code Validation: Solution: HANA’s backend was configured to flag QR codes as “expired” after one scan, securely managing entry and lunch access.

Results and Benefits

Quantitative Results:

Concurrent Multi-Device QR Scans: Over 95% scan accuracy for simultaneous QR code validations, reducing entry wait times by 30%.
Full Capacity Utilization: The 600-attendee cap was met and enforced effectively, maximizing attendance management.

Qualitative Benefits:

Enhanced Client Control: HANA’s real-time updates provided instant visibility into registration counts and QR code usage, streamlining event flow.
Secure Role-Based Access and Data Integrity: Volunteers were restricted to scanning functions, while Admins retained full data access, promoting data security.

Client Feedback: “Magnify’s real-time updates and concurrent QR code handling made managing our event a breeze. The platform handled multiple device scans smoothly, ensuring fast entry with a high level of control.”

Conclusion and Future Outlook

Magnify successfully met the client’s objectives, with HANA’s SaaS foundation powering real-time, concurrent, and customizable event management. The robust, JSON-configured structure provided a flexible platform for any event’s registration needs.

Future Enhancements:

Advanced Reporting with HANA Analytics: Plan to add attendee insights and registration trends.
Enhanced Role Access: Further customization of roles to support diverse event management requirements.

Key Takeaways:

Dynamic Customization with JSON: JSON configurations made Magnify highly adaptable to different event requirements.

Scalability and Real-Time Capabilities: HANA’s speed and multi-device support ensured smooth, reliable operations.
