With the continuous expansion of smart card applications, various non-contact applications are rapidly spreading in areas such as identity recognition, transportation, and electronic payment. The application of RFID has become a topic that people are most keen to talk about. This small chip is no longer willing to stick to the card. The mobile communication field began to integrate RFID into a three-in-one development attempt of communication, identification and electronic payment.
The mobile communication industry began to “early adopt new food”
RFID applications are mostly in the closed-loop industry chain, and the ever-growing mobile communication applications are driving RFID to open applications. Operators can use RFID tags and read-write devices to convert various information on the tags into EPC data. Through ONS (Object Naming Service), these data establish a corresponding relationship between the real object and the data in ONS. At present, the online transaction volume based on this data can reach 17 billion transactions per day, and after 2010, this number will be even greater.
Industry experts said that RFID has a broad market space in the mobile communications industry, and the prospects are very optimistic. Mobile operators hold the control of information and can carry out various value-added services such as asset custody. At present, some operators in Europe, America, Japan and South Korea have launched commercial attempts based on RFID technology. And China Mobile has also begun to explore an RFID business model suitable for its positioning.
Li Yue, vice president of China Mobile Communications Corporation, said that China Mobile will “create mobile media and create mobile phones for multiple uses” as its future development direction. Develop in-depth and extensive cooperation with manufacturers and content providers, and customize terminal products with special requirements as the focus. In the future, mobile phones will become the number one mobile portable media, which will carry media information such as newspapers, live TV, the Internet, and mobile blogs.
The mobile phone will also become the “Swiss Army Knife” in people’s lives. The payment function, entertainment function, identification function, document function, etc. developed in accordance with the characteristics of the mobile phone will enable the mobile phone to be used as a wallet, MP3, tool for identification of authenticity and a pass. He said that China Mobile is strengthening the research and tracking of RFID technology to promote the development of mobile phone product anti-counterfeiting, access control, and bus identification. Smart phone supplier Dopod also pointed out that 40% of Dopod mobile phones are currently customized jointly with operators. Recently, a mobile phone that can identify the authenticity of tobacco has been customized in cooperation with operators.
Li Yue also pointed out that China Mobile has tailored some communication products for customers in some industries, such as “Pingwutong”. All police can use our products to track crimes and pick up violations; and “Home-School Link”, through With identity recognition, parents can quickly know where their children are, when they enter school, and their learning status.
RFID “Three Streams in One”
The mobile payment industry chain is taking shape, and the use of RFID technology is to achieve the “three streams in one” function, including the mobile communication data stream we usually use, as the transaction logistics of commodities, and the exchange of capital flows. Combining information flow and logistics through capital flow can complete a complete commercial operation. Industry insiders pointed out that now mobile terminal manufacturers, payment software providers, payment system integrators, operators, and payment acceptors are actively requesting chip manufacturers to develop mobile payment technology in the market. This industry chain is rapidly taking shape. In the future, not only will it be a complete industry, but also a complete system will appear on the market.
Marui Takeshi, director of the Security MCU Marketing Department of the Standard Products Business Group of Renesas Technology MCU Business Unit, pointed out that with the passage of time and technological progress, the development of contact and contactless smart cards will also change with each passing day. It is expected that by about 2008, the application market will achieve integrated development, and multiple applications of identity recognition, financial payment, and mobile communication will be integrated, and different applications will be realized in multiple ways on one device; while the development of technology is It includes SIM card controller, RFID, mobile payment, encryption and other forms to achieve integration, winning with high-speed interfaces and high-density.
Philips Sales and Marketing Smart Card Product Greater China Regional Manager Lu Shaozu said that China has already appeared in the mobile communication industry to develop RFID technology, but how to do it is still a question mark. Domestic companies should really participate in the NFC forum to understand. Chinese companies are too inexperienced in this aspect. Most Chinese companies think of applications such as online payment. Such applications are already very advanced abroad and have been integrated into life. This is really in use, not in Play. Chinese manufacturers need to participate in discussions in the international community, understand how to apply, and then go down step by step.
It is not easy to complete transactions with mobile phones. It has certain limitations, because the operator is not a bank, and it does not have a financial operation license, so it can charge a certain, small upper limit every month, so that it cannot meet the payment needs of consumers .
Security becomes the top issue
According to Lu Shaozu’s analysis, mobile payments are currently handled in accordance with some of the existing security issues that have been discussed. For example, when paying with a card, the backend and the POS machine perform security protection before payment, because a POS opportunity has a process of communication and mutual recognition. After that, the POS machine confirms whether the card is safe and the chip content is safe. , Will it be easy to be stolen, etc. This part requires third-party authentication before it can be applied to ensure that the entire link is safe. The mobile payment we are talking about is just placing the terminal device in the mobile phone for payment, which is not much different from a POS machine.
Marui Takeshi analyzed that the development of non-contact applications, such as RFID applications, can radiate to trading platforms, transportation, and wireless applications of confidential chips. In this regard, international manufacturers are making efforts based on their respective advantages. In the field of smart cards, Samsung’s high-capacity advantages, Philips’ contactless applications and Infineon’s security-led solutions are all very competitive. In the smart card platform competition, Renesas will combine and package the flash memory controller and the SIM controller in the future, and win with a higher-speed MCU core and large capacity.
Renesas has a small-volume RFID chip u Chip, which is used in electronic tags and electronic ticketing. Marui Takeshi pointed out that it is very difficult to expand the application of RFID in the field of smart cards in China, because competition is very fierce in the field of smart cards in China. Currently, the only way to start is to develop new processes and reduce costs to ensure market share. As China’s huge demand market is concerned, we should think about how to enter the situation of healthy development and expand more market development such as security and micropayment.
