摘要：This paper presents the implementation of an Android App and an Arduino controlled QR code displaying system that can be used for Suburban Railway Ticketing. This paper describes use of QR code for ticketing and steps used for storing QR codes in the Arduino UNO. The user can use the app to book ticket and inbuilt wallet for payment but it is compulsory for the user to scan the QR code, displayed on one of the Arduino controlled systems fixed at the station, using the same app. The QR code contains information about the Source and some other validation details which is encrypted using Vigenère cipher. The QR code on the system changes every 5 minutes. Each QR code is encrypted using different key. The app contains the key and the QR code data is decrypted in app itself and it fetches source station from the decrypted text and calculates fare. Finally the app generates a ticket and stores in the database. The App uses Google Vision API for scanning QR code and PayPal payment gateway to add money to wallet.
