Introduction of dual interface card

Dual interface card (also known as combination card/dual port card) is a multi-function card that combines both contact and non-contact interface communication. It combines the convenience of contactless IC card with the safety and reliability of contact IC card. The integration makes it an excellent carrier for multiple cards, representing the main development direction of future IC cards. The dual interface card is not only suitable for occasions such as urban public transportation, road tolls and electronic wallets, but also meets the needs of financial services and e-commerce that are more concerned about safety and reliability. It has become another competitive hotspot in the card market.


Dual interface card's advantage

One card for multiple usage

The card supports multiple applications: one card can integrate multiple different applications, multiple industries, multiple applications and simultaneous card issuance. The application is flexible and convenient. According to different application conditions and requirements, it can optionally adopt contact or non-contact transaction mode to reduce operating costs. It is applicable to the trial environment with large transaction volume, short trading time and no waiting process during the transaction process; Applicable to harsh working environment and self-service consumption places, strong anti-destruction and anti-interference ability; suitable for systems with high security requirements, can be used as financial e-wallet application; card anti-collision mechanism, allowing multiple cards to enter the transaction area at the same time; Traditional contact devices are fully compatible and can be used directly on them

Highly secure

Chip security: The chip with random data generator can prevent physical and logical attacks. The program code COS in the chip can not be reproduced once written; each chip has a unique factory code. OS security: Supports singleDES and TripleDES algorithms: Automatically selects singleDES or TripleDES algorithm based on key length; supports line encryption and protection to prevent traffic data from being illegally stolen or tampered; multiple key types support different ways of using keys . Transmission security: Data transmission in non-contact mode follows the relevant transmission protocol. After encryption by card and machine, the data will not be leaked even if it is intercepted.

Fast Trading

The chip contains DES operation accelerator, which can quickly complete algorithms such as SingleDES and TripleDES. The operation time of one TripleDES is 130 microseconds; when contactless communication, the communication transmission rate is 106KBPS; the communication speed of the contact part can be adjusted, and the communication speed can reach 38400bps.

Good compatibility

It complies with the requirements of China Financial Integrated Circuit (IC) Card Specification; it conforms to Type A in ISO14443 standard, and the later dual-interface card based on Siemens chip supports Type A or Type B. At present, the tools that support Mifare-I card reading and writing can easily read and write the Mifare-Pro type TimeCOS/DI that supports Type A only by software upgrade.

Dual interface CPU card packaging process description

As a new technology, the dual interface CPU card has its special requirements for card packaging. There are two main packaging processes currently in use: lamination and injection molding. Compared with the ordinary contact card, the dual interface card adds a set of antennas, and also increases the difficulty of the card packaging process. At present, there are certain problems in using the dual interface card packaging process: the antenna is a non-contact type chip and a reading and writing machine. The medium for energy transfer and communication is generally in the package. The contact between the antenna and the chip is connected by conductive rubber. Due to the problem of process and conductive rubber, the connection between the antenna and the contacts of some cards is unstable, often There will be a situation where the non-contact interface cannot work normally after the package is completed or used for a period of time. In the application test, the proportion of the card non-contact interface that cannot work normally due to the packaging problem accounts for the vast majority of the card failure rate. However, some German manufacturers use some flexible conductive adhesives for packaging, and the reliability is also very good, and this situation will not occur. At present, domestic enterprises have not mastered this technology. In addition, the company has adopted a unique packaging process in the package of the dual interface card, that is, the automatic wire picking and soldering package, the antenna and the chip are firmly welded together by soldering, and the antenna and the contact of the dual interface card are solved. The connection problem makes the connection between the antenna and the contact more reliable and reliable, and the cost is lower. Due to the application of this technology, the package yield of the dual interface card and the failure of the non-contact interface in use have become great. cut back.
