Standardized and Decentralized Ticketing System

This paper introduces a novel approach to revolutionize public transport ticketing systems through the integration of decentralized technologies, namely cryptocurrency and NFTs utilizing a decentralized wallet storing both cryptocurrency for payments and NFT-based digital identities containing user credentials. This system empowers users with granular control over data privacy through on-device verification requests and zero-knowledge proofs, promoting standardization, decentralization, and enhanced user privacy in public transportation ticketing system.
