Valet Ticket Automation Application

This application aims to automate the general flow of valet parking systems by handling the ticket generation, payment, and verification of payment digitally.

This is the item to be reviewed in this repository

How It Works

There are 2 parts of the application. A user-facing application. And a version for the valets/parking attendants. Upon arrival, the user simply has to provide his/her name, phone number and the car's details to the valet. The valet will generate a ticket for them using the application. And the user will get a link through SMS, to view the ticket and associated details. The user can also pay for the ticket. However, the payment system has not been integrated in the current version of the application. When the user wants to leave, instead of handing over the ticket physically to the valet & waiting for the car to arrive, he/she can simply pay for the ticket online and then "Call Car" beforehand. They will receive a QR Code at this point, from the application. This has to be shown to the valet. And the car will be waiting to be picked up - without any wait.
