Dynamic QR Code for Event Entry
Why Choose This Project:
Traditional event entry methods like printed tickets or static QR codes can be prone to fraud, duplication, and long entry queues. A dynamic QR code system generates unique, time-sensitive codes for each attendee, enhancing security, speeding up entry, and enabling real-time attendance tracking.
What You Get:
-
A secure system for generating dynamic QR codes for event attendees
-
Real-time verification at entry points
-
Admin panel to manage events, attendees, and scans
-
Analytics on attendance and entry times
-
Optional integration with payment gateways for ticket purchases
