1 Overview
IC card, especially non-contact IC card/RFID (hereinafter referred to as non-contact IC card and RFID collectively referred to as RFID) has been developed in various corners of modern life after more than ten years of development, and is widely used in public transportation, access control, small electronic payment, etc. field. In recent years, under the impetus of rail transit, logistics management, anti-counterfeiting, and identification, the RFID technology has been continuously improved and its application has become more and more popular. Various types of RFID identification devices are urgently needed. At the same time, the mobile communication terminal has experienced rapid development for more than 20 years, and has become a portable device for the residents. The penetration rate is very high, and there is a tendency to integrate more functions into the mobile terminal.
If the killer application that promoted the development of the semiconductor industry in the 1980s and 1990s was a PC, the killer application that promoted the development of the semiconductor industry in the 1990s and 2000s was a mobile phone, then the next killer application that may become a new killer in the last decade or so will be combined with mobile. Terminals and RFID technology are used in one machine (card). Especially in the 3G era, RFID with wireless connectivity and ubiquitous RFID readers and contactless applications will be the focus of attention. At present, there are two solutions based on contactless technology in the industry: Combi SIM card solution and NFC (Near Field Communication) solution.
The Combi SIM (also known as Dual Interface) card solution refers to adding a non-contact IC card application interface based on the SIM card function of the original contact interface by replacing the internal SIM of the mobile phone instead of the Combi SIM card. The Combi SIM card solution adds the functionality of a contactless IC card to the phone, but does not implement reader and duplex communication.
NFC (Near Field Communication) is an emerging technology that has developed rapidly in recent years. It was proposed by Sony, Philips and Nokia. It enables two electronic devices to communicate directly in short-range, working in the 13.56MHz band, working distance. A few centimeters. The NFC technology aims to provide close-range communication between electronic devices. In the actual promotion process, it faces many difficulties. At present, its main application areas are concentrated in close-range payment applications, and NFC technology and SIM related solutions are being sought.
Although the above two solutions are technically feasible, for a multi-purpose (card) multi-purpose, the core is how to rationalize the relationship between mobile device manufacturers, mobile service operators and application service operators in this cross-industry. In the integration of new applications, a balanced and balanced approach is needed. The SMAP (Intelligent Mobile Application Platform) solution proposed in this paper can be applied to many types of applications such as mobile payment, product anti-counterfeiting, tracking supervision, digital signature, identity authentication and information acquisition. It is a balanced evolution of mobile terminals and RFID. road.
2. Architecture of the SMAP platform and its applications
2.1. Architecture of the SMAP platform
Based on existing contactless IC card applications and mobile communication applications, the SMAP platform further integrates various application environments and security systems to form smaller, safer, lower-cost and more convenient high-frequency. The RFID application environment, the structural block diagram of the SMAP platform is as follows:
In the architecture of SMAP platform, SMAP module (chip), security system and middleware products constitute its core content. Here, SMAP module (chip) is defined as a security system, which can be imported by application and provided by external middleware. Serving high frequency RFID applications.
2.2. Architecture of the SMAP platform
As mentioned earlier, the SMAP platform is a solution for combining mobile terminals with RFID applications. The basic architecture is mobile communication terminal + SMAP module + RFID, as shown in the following figure:
The SMAP module is integrated with the mobile communication terminal through the interface circuit, and the RFID is also integrated on the mobile terminal, wherein the RFID can be a separate part of a single column or integrated with the SMAP module. A single column of independent RFID can accept the RF operation of the SMAP module, and the purpose is to achieve a good balance between the status quo. As mentioned above, the card technology with non-contact IC card as the core technology has been widely used in China. Typical and mature application industries such as bus card, campus card, etc., credit card consumption as a kind of small consumption in these industries For reception, and a de facto interest relationship has been formed. On the other hand, under the current system of China, in addition to banks and their related units, there are great institutional obstacles for other units to issue gold cards. Therefore, in the mobile payment service, RFID appears as an independent way, which can ensure the implementation of the mobile payment service, and can also take into account the interests of the card issuer. At the same time, the bank card can be directly used for the new card issue to avoid the policy. risk.
2.3. Development path of SMAP module
In the architecture of the above application, the core is the SMAP module. In the current state, the SMAP module is a multi-chip module with built-in security features and application flow. The structure of the module is as follows:
The SMAP module consists of three chips and several discrete components. The core chip is the main control MCU, which includes the IO interface and power management control interface. The Reader is a universal RFID reader and supports access to the ISO14443 type A, type in the 13.56MHz band. B standard and ISO15693 standard products; RFID is an independent electronic tag module, which can independently package the antenna, communicate with Reader through RF coupling, or integrate with the module to share an antenna.
As mentioned earlier, for a multi-purpose (card) multi-purpose, the core is how to rationalize the relationship between mobile device manufacturers, mobile service operators and application service operators. Cross-industry application integration requires a balanced, gradual, and balanced approach. The following figure illustrates the development of the SMAP solution.
RFID discrete SMAP solution antenna sharing SMAP solution single chip SMAP solution
The first solution is to adopt an independent RFID SMAP module solution. The advantage of this solution is that independent RFID can introduce existing contactless application operators with low barriers, and the distribution and application modes remain almost unchanged, supporting non-contact power-down application mode. The scheme is applicable to the pilot period of the initial concept of the new application; the second scheme is that the RFID and the SMAP module are integrated and share one antenna, and the scheme 2 has the same function as the scheme one, and the advantage is that the independent RFID tag is reduced. The size affects the design of the handheld mobile terminal, but requires the cooperation between the application operator and the mobile operator and the mobile phone manufacturer. The solution is suitable for the promotion period of one machine multi-purpose; the third solution truly integrates the SMAP module into A single chip that supports the ISO18092 standard and links the SMAP application to the SIM is a truly large-scale solution based on market feedback after the first two trials.
