QR Pocket
QR Pocket lets users store and organize QR codes for family, friends, businesses, and frequently used contacts in one place, with instant scan, save, categorize, search, and WhatsApp-integrated reuse.
Problem Statement
People accumulate dozens of QR codes (UPI IDs, Wi-Fi credentials, business codes, contacts) with no organized way to store or reuse them, forcing repeated re-scanning or searching.
Proposed Solution
A client-side app that saves, categorizes, and indexes QR codes locally, with one-tap reuse and direct WhatsApp integration for saved contacts.
Main Features
- QR code storage and categorization
- Instant scan, save, and search
- Support for UPI, Wi-Fi, contact, and business QR codes
- WhatsApp integration for saved contacts
- Local data storage for fast, offline-friendly access
Technical Architecture
A responsive client-side web app using local storage for QR data persistence, with a scan/save/search UI and WhatsApp deep links for saved contacts.
Challenges & Solutions
Keeping QR retrieval fast and organized as a user's saved-code list grows.
Built categorization and search into the core data model from the start, instead of a flat list.
Results & Impact
Delivered as a client project for Krishna; client feedback highlighted it as a convenient, user-friendly solution for managing personal and business QR codes.
“A convenient and user-friendly solution for securely managing personal and business QR codes while simplifying communication through WhatsApp.”
Future Improvements
- Cloud sync/backup for saved QR codes
- Expiry reminders for time-sensitive codes
- Batch export/import of saved codes
