First, the meaning of the dual interface smart card
The IC card is a smart card made by embedding an integrated circuit chip with storage, encryption and data processing capabilities in a plastic substrate of the same size as a credit card. In general, it can be divided into contact type and non-contact type. Two types. When the IC card is in use, it needs to be inserted into the card reader to realize the transmission of commands, data and card status through the physical contact of the electrode contacts on the surface. The non-contact type IC card can be used as long as it is close to the card reader, and the card and the card reader transmit information by means of radio waves or electromagnetic fields. The power of most non-contact IC cards is also obtained in this way. It is generally required that the distance between the card and the external interface be within 2 to 3 inches.
Contact and contactless cards have their own advantages and disadvantages due to their use environment and amount of information exchange. Therefore, with the development of the information age, the dual-interface smart card (that is, supporting contact communication and non-contact communication) that can meet the requirements of wide use has become a hot spot in the international pursuit. Currently, dual interface cards have three solutions: one is completely independent of contact and non-contact, and is physically composited on one card; the second is contact and non-contact are independent of each other but share some storage space; last one The contact is in the same state as the contactless operation and is controlled by the same processor. We can say with certainty that only the third dual interface card is a true dual interface card, such as: TimeCOS/DI.
The origin of smart cards in Europe, from the concept of intelligent IC card in 1972, to the first single-chip smart card made by Boer in 1978, has developed into today, people are no longer strange to smart cards, smart cards have been used in many fields.
The development of smart cards in China is changing with each passing day. The design and production of chips are gradually becoming domestically produced, and the packaging process is becoming more and more mature. However, it is worth mentioning that the operating system of domestic independent copyright has reached in just a few years. At the international level, Beijing Wins Data Systems Co., Ltd. released the world's first dual-interface smart card TimeCOS/DI released on December 21, 1999, indicating that domestic products have been synchronized with the world, which represents the grip of Qiqi. Success, but more representative of the success of the domestic smart card industry. Throughout the development of domestic smart card technology and market, we should be gratified and proud from the monopoly of foreign manufacturers and the equalization of domestic and foreign manufacturers.
Second, the application advantages of dual interface smart cards
A dual-interface smart card that represents the world's smart card development of the latest technology, regardless of the advancement of technology, the applicability, convenience, and rationality of product use, or the comprehensive performance price ratio, and the investment in the distribution of reading and writing equipment, the dual interface Smart cards have great advantages over the currently widely used Mifare One, Combi and other cards. These advantages are reflected in many aspects of the application, such as security, reliability, support for multi-purpose versatility, etc. These powerful advantages have enabled the dual-interface smart card to be predicted by international smart card experts to become the mainstream product of smart card development before the advent of the dual-interface smart card. In fact, in the short period of time since the advent of the dual-interface smart card, she It is indeed becoming the star of the smart card industry, how many problems in the smart card application industry, and the emergence of dual-interface smart cards will be tough.
The dual interface smart card includes a microprocessor chip and an antenna coil connected to the microprocessor. The electromagnetic field generated by the reading and writing device provides energy. The card itself does not need a battery. The reading and writing device can activate the card, transmit commands, accept card signals and Calculate the operation. If it does not consider its non-contact function, it is a common CPU card that conforms to traditional standards and application habits. It conforms to ISO7816 and PBOC requirements for cards, and is fully compatible with contact card application systems and reading and writing implements, and the contact method and The contactless mode is controlled by the same CPU, sharing all resources of the card (storage space, e-wallet, security mechanism, etc.).

Third, dual interface smart card technology
Does new technology necessarily mean immaturity? Does the new product necessarily mean unreliable? Absolutely, it is not objective.
For the company's TimeCOS/DI, its support for TAPE A is based on Philips' Mifare technology. Products using Philips Mifare technology have issued more than 10 million cards, mature or not, and we dare not assert that a large group of cardholders will have a say.
The technology development of dual-interface smart card has experienced the development speed of dual-interface smart card, and the development of dual-interface smart card must comply with the development requirements of e-commerce era. The new dual-interface smart card product, with its existing features, has a Crpto-engine (coprocessor) that supports RSA key pair generation, encryption and decryption, digital signature and authentication.
With the application of flexibility, convenience, versatility and other requirements, the technical development of dual-interface smart cards has higher requirements: hardware, 16/32 bit-CPU, large-capacity ROM, RAM, EEPROM In terms of performance, it is possible to flexibly install JAVA applications, etc. In terms of functions, it can realize mobile e-commerce.
Fourth, pay attention to dual interface smart card
Focus on dual interface smart card, support dual interface smart card!
Since the advent of dual-interface smart cards, it has been supported by many industries. Many industry authorities have combined with the application requirements of the industry, and clearly proposed to use dual-interface smart cards in the development of norms or standards to promote the development of dual-interface smart card technology and applications. At the same time, it also meets the requirements of the application characteristics of the industry. On the other hand, while the industry authorities have formulated the norms and standards of the industry, they have also fully considered the integration with international standards and relevant domestic industry standards. The application of the dual interface smart card is open, flexible and adaptable, and it has injected vitality into the application of the dual interface smart card.
Supporting the dual-interface smart card products pioneered by China and making China's smart card industry proud, is our high hopes for the majority of users.

2.TimeCOS/DI cost analysis
The price of TimeCOS/DI, which is so superior in performance, function, and use, is lower than the price of a PBOC-compliant contact CPU card with a capacity of 8K bytes and a Mifare One card. Ignoring the latter's combination of dual investment in the issuance of equipment and reading and writing equipment, the so-called dual interface card is too expensive and needs to be based on evidence.
However, it is also impossible to face the fact that the dual interface smart card is currently relatively expensive. The so-called relatively high is because she still has the space to cut prices, the trend of price cuts.
The rapid development of the integrated circuit industry, as well as a large number of applications, usually affect the price of the chip, making it a trend of price cuts.
On the other hand, there are currently two packaging processes for TimeCOS/DI: injection molding and lamination. The injection molding process is a new process developed in the near future, and although the traditional process is laminated, the packaged dual interface smart card needs to be improved. Production line, so the current package of TimeCOS/DI mainly relies on overseas packaging, processing costs, tariffs, etc. will affect the price of the card. After the domestic packaging process is gradually matured, the price of the card should have room for price reduction.
