【Editor’s Note】RFIDAnd contactless IC card chip is the most critical core link in RFID and contactless IC card products.In recent years, with the globalsmart cardWith the rapid development of the RFID industry, RFID and non-contact IC card chip technology have been rapidly developed, and the product categories have become more abundant. In order to fully reflect and promote the latest technology and products of RFID and non-contact IC card chips, according to user needs,RFID China NetworkIn response to user needs, a large-scale online publicity topic and e-book activity of “RFID and non-contact IC card chip brand shopping guide” was specially launched to meet users’ needs for understanding of RFID and non-contact IC card chip brands, technologies, products, and applications. This article is “Shanghai Huahong Contactless CPU Card Chip Application on Bus Cards” provided by Shanghai Huahong Company for users to understand and refer to.
In 1999, the Shanghai public transportation card project adopted China’s first contactless IC card chip with independent intellectual property rights designed and developed by Hua Hong. The project is the world’s most comprehensive “all-in-one card” and the world’s largest AFC project. In 2009, Hua Hong designed and launched the non-contact CPU card chip SHC1108, which conforms to the “Technical Requirements for Non-contact CPU Card Chips in Construction Business” standards, and is used in the upgrade of the national public transport card.
Domestic transportation IC cards are still using contactless logic encryption cards in many cities. However, with the continuous expansion of bus business in recent years, the bus card system is facing the pressure of upgrading and transformation, and new requirements for IC cards are also put forward:
1. IC cards need to accommodate more and more industry information, while the original logical card capacity is mostly 1k bytes, the application space left for new industries is already stretched, and the bus industry needs IC cards to provide more storage space .
2. The transaction reliability of the original logic card is basically guaranteed by machinery, so the impact of abnormal interruption on transaction data is inevitable. The bus industry needs IC cards to automatically maintain transaction data to ensure transaction reliability.
3. Inter-city interconnection is the direction of the development of public transport, but there are differences in the encryption algorithm, card structure, and operation process of the original logical card in each city, which hinders the process of interconnection. The public transportation industry needs an IC card that meets the unified specifications to accomplish this goal.
4. The bus card business has the characteristics of wide coverage, many users, and complex industry relationships. A comprehensive IC card system upgrade is never a matter of overnight. Choosing a card that can adapt to the original logic card system and smoothly transition to The IC card of the new system can solve the upgrade problem very well.
5. As we all know, the well-known MIFARE ONE logic encryption card algorithm has been cracked, and a set of efficient card copying methods for the logic card has also appeared. For an industry with tens of millions of funds flowing every day, this is a huge threat. Therefore, it is urgent to choose an IC card with a more secure encryption algorithm.
With so many new requirements, we naturally think of the contactless CPU card that has been developing rapidly in recent years. The non-contact CPU card is a kind of intelligent IC card, and the storage capacity is generally above 8k bytes. It usually uses DES/3DES encryption algorithm, its transaction process is simple, and the transaction data is automatically maintained by the card, so it has high security and reliability. On this basis, the non-contact CPU card SHC1108 independently designed by Shanghai Huahong has added new functions: it can simulate all the functions of the logic card, and the CPU can control the data of the logic card, and it can be completely cut off by simple settings. The logic card channel becomes a pure CPU card with high security. This feature of SHC1108 provides a great help for the smooth and stable upgrade of the bus card system in various cities.
According to the actual situation of each city, the one-card company can choose between two non-contact CPU card application schemes: for cities that have not yet launched the bus IC card business, or although the bus IC card business has been launched, it can be used in a short time. Prefectures and cities that have completed the upgrading and transformation of all machines can directly choose the standard non-contact CPU card application program. This solution can reduce costs for owners, shorten the development cycle, and more conveniently enjoy the advantages brought by contactless CPU cards.
For cities that already use logical encryption cards and need a longer upgrade transition period, non-contact CPU cards with logical interfaces can be used to complete the smooth transition of the bus IC card system. This non-contact CPU card has two transaction interfaces, logic and CPU, and COS automatically maintains the synchronization of the CPU wallet and logic wallet. During the transition period, the modified machines can be used for recharge and consumption transactions through the CPU interface, while the unmodified machines can still be consumed through the logical interface. After the upgrade is completed, the logical transaction interface can be easily closed through each business terminal , Making these cards a standard contactless CPU card. This transformation plan fully takes into account the long-term nature and complexity of the system upgrade, and can greatly reduce the cost and difficulty of the system transformation for the all-in-one card company.
The process of using the non-contact CPU card to upgrade the bus card system can be divided into the following three stages:
Phase 1: Gradually issue contactless CPU cards with logic card functions. At this time, the logic channel of the CPU card is in an open state, and all the data structures of the logic card are the same as the pure logic card. The machines in the bus system use such a CPU card as a logic card.
Phase 2: Gradually carry out the transformation of recharge and consumption equipment. The new equipment can support both logic cards and CPU cards. At the same time, CPU cards can be used on both new and old equipment. Because the CPU card has the ability to control the wallet of the logic card, the wallet of the CPU card and the logic card can always be consistent. This state of coexistence of new and old machines, and the coexistence of logic cards and CPU cards will last a long time, and the ability of the CPU card to synchronize logic wallets with CPU wallets has laid a solid foundation for the smooth transition of the system.
Stage 3: The original logic card recovery work and the equipment transformation work are basically completed. At this time, the logic channel of the contactless CPU card can be completely closed through the recharge equipment to become a pure CPU card. At this point, the wallet balance in the original logic card is still valid in the CPU card, and the system has completed the upgrade process from the logic card to the CPU card.
Highlights of the application case:
1. Complete and flexible solutions According to the actual conditions of each city, Shanghai Huahong Integrated Circuit Co., Ltd. provides two non-contact CPU card application solutions:
1) For cities that have not yet launched bus IC card business, or where bus IC card business has been launched, but can complete all equipment upgrades in a short time, you can directly choose the standard non-contact CPU card application program . This solution can reduce costs for owners, shorten the development cycle, and more conveniently enjoy the advantages brought by contactless CPU cards.
2) For cities that already use logical encryption cards and need a longer upgrade transition period, non-contact CPU cards with logical interfaces can be used to complete the smooth transition of the bus IC card system.
2. Diversity of product selection. The SHC1108 series of non-contact CPU card chips of Shanghai Huahong Integrated Circuit Co., Ltd. includes two types of standard non-contact CPU cards and non-contact CPU card chips with logical interfaces, which can be matched with Huahong The solution is flexible to choose to meet the different needs of customers.
3. Mature public transport project experience As early as 1999, the Shanghai public transport card project adopted China’s first contactless IC card chip with independent intellectual property rights developed by Shanghai Huahong Integrated Circuit Co., Ltd. This project is the world’s most The complete “all-in-one card” is also the world’s largest AFC project. In 2002, Wuxi officially opened the non-contact IC card toll operation system for public transportation. Hua Hong’s non-contact IC card chip was used to realize the intercity inter-city communication between Wuxi and Shanghai public transportation cards. This is the first time that the two places have achieved transportation in China. Card intercommunication. In 2012, the eight cities of Shanghai, Ningbo, Shaoxing, Taizhou, Huzhou, Changshu, Lanzhou, and Baiyin will achieve interconnection, which will comprehensively promote the overall application of one-card interconnection in cities across the country, and will become an important milestone in the development of the national urban all-in-one card industry .
The mature operation experience of these public transportation projects gives Hua Hong more advantages in the upgrade of non-contact CPU card public transportation applications, thereby gaining the trust of customers, and establishing Hua Hong Design as the core chip supplier in the public transportation card project.
