Description

200847753 IX. Description of the Invention: [Technical Field] The present invention relates to a dual card system for use in a communication terminal or a transaction terminal, and more particularly to a dual card system having two card slots for a communication terminal.曰 【Prior technology】

In general, smart cards are commonly used in two areas. One is the Subscriber Identity Module (SIM) for wireless communication, and the other is the identification system, such as a financial card, credit card or secret card. The SIM card enables the Kawasaki mobile communication device to use a wireless network system, such as a GSM or CDMA system, to have a SIM card issued by a related communication service company. The SIM card stores the user information 'including the user's phone number, phone book, dialing restrictions, personal identification number (PIN), personal unlock code (ρυκ), and the like. Furthermore, a non-counterfeit SIM card is accepted by the communication system for communication, so that the user can be allowed to enter the GS1V [communication network to transmit information. In general, a SIM card is also called a plug-in size card, and its size is about 25 mm long and 15 mm wide. Only the copper portion is actually used for connection. When the card is connected to the mobile phone, there are at least five cards between the two, which are composed of five parts, including cpu, RAM, R〇M: EEPROM or Flash, and serial communication unit. Bribes in s news contain (1) leaking "in the control channel information; _ interaction with ^ identification code (IMSI) and temporary action user lang code (_); (7) record and secret algorithm; _ person servancy code _) money People unlock the stone horse " 5 200847753 (PUK) ' and (5) SIM card application tool set (STK).

Ik is widely used in the communications industry, such as SIM for QSM, USIM for WCDMA, RmM for cdma2〇〇〇, and PIM for PHS network, currently using smart card applications. For mobile phones (SIM/USIM/RUIM/PIM, next will be a universal integrated circuit card

In the UICC system, a variety of different applications have been developed to provide security services. The operators are authenticated by the mobile operators to store them in smart cards, and the gold materials ensure the security of the use of mobile services. In addition, operators also provide additional services, such as mobile banking and mobile stock market trading services, through the gold records provided by banks or other service providers stored on SIM cards. These gold are manipulated through the application interface by the SIM card application tool set (STK) stored in the SIM card. Since the beginning of the wireless application, the m-phone SIM card manufacturer has also developed the Wireless Identification Module (WIM), which is stored in the SIM (SWIM card) by the authentication and pKI/Ziyi method or another early insertion. The mobile phone in the other _ card slot ^ guarantees the security of the WAP. τ木真行, card issue = public with silver, is a capability 6 200847753 This is a closed system, only allows the recognition of the relationship between the 'service provider and the operator's relationship, for each other ^ Second, both control for security and payment are similar, ~ the biggest obstacle to the development of full-service service. Therefore, this issue is the above. Oral solution On the other hand, the traditional smart card is IS0 size, 84 m long and buckle 5 > 4 house meters. Generally speaking, it is applied to financial transactions (four), such as financial cards, credit cards, cash cards, or identification systems such as health insurance cards.

[Embodiment] The present invention discloses a dual card system for use in a communication terminal or a transaction terminal such as a mobile phone or a personal digital assistant (PDA), such as an automated teller machine (ATM) or an endpoint sales system (POS) ) Card reader. The above application will be explained in more detail below. In this embodiment, the communication terminal has two card slots for simultaneously placing two different cards. The main feature of the present invention is that the two cards are 200847753 _ 如同 如同 邪 邪 Γ M u - a sentence widely used in the field is controlled by the communication terminal J, but Zhang card (here called The "sub-card" is controlled by another card (here called the second card). In this way, manufacturing such as a Subscriber Identity Module (SIM) card, a universal user field in the 丨> / a shouting (7) pull group (USIM) card, a user identification module (UIM) card, a removable use secret, a 7 π service The communication service provider of the integrated circuit card, such as the heart-shaped u + test identification module (RUIM) card, will be able to control the additional functions and services that it wants to provide.

For example, the additional fee and the SI]U M Tool Application Kit (STK) should be used to activate the bank, act on the stock market, and so on. Please see Figure 1. 2 is a block diagram of a dual card system in accordance with the present invention. The communication terminal 10 includes a pair of cards 12 and a main card 11. The main card 11 is an electrical connection f between the communication terminal unit 1G and the sub-card 12, and has a processor 13 for controlling the sub-card 12. ^ Card or Leica 12 can be a communication card, such as user identification module, and (SIM) card, universal user identification module (USIM) card, user identification module (flM) card, removable user identification Module foot) card and so on. In addition, when the card 1 is a universal card, the card 12 can also be a transaction card, such as a card ATM card, a cash card, a credit card, or a stored value card. On the other hand, when the secondary card 12 is a communication card, the primary card η can also be a transaction card. Similarly, the secondary card 12 or primary + 11 ... h " may include a Wireless Application Protocol Identification Module (WIM) to provide security services for medical applications. The card 11 or the secondary card 12 may also be an identification card, a memory card, a health insurance card, or an employee card 12, and has an expandable memory 14 for increasing the storage capacity. 200847753

In addition, the main card 11 has a network security function such as network access control, mail encryption and electronic signature based on an electronic signature and a private key stored in the IC card memory. The secondary card 12 has a security function, but this security function is not limited to the network security functions described above, and may be data security functions such as data encryption to protect the data stored in the expandable memory 14 of the secondary card 12. '

The primary card 11 or the secondary card 12 may have an antenna coupled thereto to enable remote access between the communication terminal and a transaction terminal such as an automated teller machine (ATM) or an end point sales system (p〇s) card reader. Wireless transactions. This antenna can be a layered inductive coil antenna or a planar antenna. In the present invention, the sky and the line are not fixedly connected to the main card 11 or the sub card 12. It can be a detachable antenna. As described above, the sub-card 12 and the main card 11 are not controlled by the communication terminal independently as those which have been widely used in the field. Instead, the secondary card is controlled by the primary card 11. Therefore, upon receiving the request from the communication terminal 5 10, the processor 13 of the main card 11 determines whether or not the secondary card 12 is to be activated. In other words, the main card 11 can control the communication between the communication terminal 1 and the secondary card 12, and reorganize the response signal of the secondary card 12 to the communication terminal to implement its additional application, such as the second wireless communication. ★壬壬甩"Gu Hu code registration and switching, SIM card application tool group (for example, Mobile Bank, ^ ^ or WAP Identification Module (WIM) security features, etc. ~上μ又
