Realized Application of a Contactless CPU Card for Public Transport Interconnection

摘要

Public transport cards from various cities cannot achieve transactions in other cities. This means they fail to meet current technological development trends and public travel demands. This paper puts forward a method to realize contact-less CPU cards that feature cross-regional, cross-transportation-modes, as well as cross-industry interconnections in public transport. It does so by unifying the public transport card system composition, card files and application requirements, terminal transaction flows, clearing and settlement information interfaces, as well as the contactless interface communication, security system, test system. This method features compatibility between advanced financial electronic cash applications with traditional public transport card electronic wallet applications. It also features dual application shared files and balances, the national transport One-Card clearing and settlement platform building, as well as cards with international UN and RID codes, the compatibility of a dual key system and dual algorithms, dual-coin function support. At present, more than 200 cities in China have joined the transport One-Card interconnection. More than 12 million One-Card interconnection cards have now been issued, and the national transport One-Card clearing and settlement platform has processed 30 million data exchanges after more than two years of application and implementation. The successful realization of the national transport One-Card interconnection has been improving the standards of public travel service and management in the transportation industry. It has also been useful for promoting the healthy development of the transport One-Card industry.
