Design and Implementation of QR Code Generation and Verification System Using Raspberry Pi for Smart Parking and Billing

This paper presents the development and implementation of an automated QR Code Generation and Verification System using Raspberry Pi for smart parking management applications. The proposed system is designed to automate parking operations, enhance security, and ensure efficient management of vehicle entry and exit processes. At the time of vehicle entry, the system generates a unique Quick Response (QR) code acting as a digital ticket, which is printed via a thermal printer for the user. Concurrently, an image of the user is captured using a USB camera and securely stored in local storage as a backup measure. During vehicle exit, the system scans and decodes the QR code. Upon successful verification against the stored database, the system automatically computes the total parking duration and calculates the corresponding fee. The results demonstrate a reliable, secure, and efficient solution that minimizes manual intervention, reduces operational errors, and ensures accurate billing.
