## Description

The CO Checker app is a public transit ticket verification tool designed to streamline the boarding process. Ticket Checkers begin by logging in with their phone number and OTP. After login, they can choose the transit (Metro, Suburban or Bus) and the verification method— by scanning a QR code. The app guides the user through camera access and QR scanning. Based on the verification result, the user sees a clear status: valid, expired, or invalid ticket.
