QR Verification Mobile App

Sobre el Proyecto

The QR Verification System is a mobile web application conceived for inspectors and gate staff at events or restricted access points.

The sole and crucial objective of this app is the swift scanning of a member's digital ID using a mobile device's camera, instantly returning their payment status (Up-to-date / Pending / Not Registered).

This tool significantly reduces physical queue times at access gates and eliminates the reliance on printed lists or spreadsheets, offering a lightweight and robust real-time solution.
