With the continuous expansion of smart card applications, various contactless applications are rapidly spreading in the fields of identification, transportation, and electronic payment. The application of RFID has become the topic that people are most keen to talk about. This small chip is no longer willing to stick to the card. The field of mobile communications has begun to integrate RFID into a three-in-one development attempt for communication, identity, and electronic payment.
The mobile communication industry began to "early adoptive"
RFID applications are mostly in the closed-loop industry chain, and the growing use of mobile communications is driving RFID to open applications. Operators can convert various information on the tag into EPC data via RFID tags and read/write devices. These data establish a corresponding relationship between the physical object and the data in the ONS through the ONS (Object Naming Service). At present, the online transaction volume based on this data can reach 17 billion pens/day. After 2010, this number will be even larger.
Industry experts said that RFID has a broad market space in the mobile communication industry, and the prospects are very optimistic. Mobile operators hold 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 already launched commercial trials based on RFID technology. China Mobile has also begun to explore the RFID business model suitable for its own positioning.
Li Yue, vice president of China Mobile Communications Corporation, said that China Mobile will "create mobile media and create multi-purpose mobile phones" as the direction of future development. Intensive and extensive cooperation with manufacturers and content providers, and customized end products with special requirements have become the focus. In the future, mobile phones will become the first mobile and portable media, which will carry media information such as newspapers, live TV, 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, and document function developed for the characteristics of the mobile phone can make the mobile phone as a wallet, MP3, a tool for 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 anti-counterfeiting, access control and bus identification. Smartphone supplier Dopod also pointed out that 40% of Dopod mobile phones are currently customized with operators, and recently there is a mobile phone that can be customized with operators to identify the authenticity of tobacco.
Li Yue also pointed out that China Mobile has tailor-made some communication products for some industry customers, such as “Police Serviceâ€. All police officers can use our products to track crimes, pick up violations, and “home-school communicationâ€. Identification, parents can quickly know where the child is going, school time and learning status.
RFID "three streams in one"
The mobile payment industry chain is taking shape. The adoption of RFID technology is the realization of the "three-in-one" role, including the mobile communication data stream that we usually use, as the transaction logistics of goods, and the exchange of funds. By combining the flow of information and logistics through capital flows, a complete business operation can be accomplished. Industry insiders pointed out that nowadays, mobile terminal manufacturers, payment software providers, payment system integrators, operators and payment acceptors are actively asking chip manufacturers to develop mobile payment technology in the market. This industry chain is rapidly forming, not only a complete industry in the future, but also a complete system in the market.
Marui Wu, Director of the Safety MCU Marketing Department of the Standard Products Group of Renesas Technology MCU Division, pointed out that with the passage of time and advances in technology, the development of contact and contactless smart cards will also change with each passing day. It is expected that by 2008, the application market will achieve integrated development, and multiple applications of identity, financial payment and mobile communication will be integrated to achieve different applications in a variety of ways on one device; while technological developments Including SIM card controller, RFID, mobile payment, encryption and other forms of integration, high-speed interface, high-density win.
Lu Shaozu, regional manager of Philips' sales and marketing smart card products in Greater China, said that China has emerged as a trend in the development of RFID technology in the mobile communications industry, 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 respect. Most Chinese companies think of applications such as online payment. Such applications have been advanced abroad and have been integrated into life. This is really in use, not in play. Chinese manufacturers need to participate in international groups to discuss, understand how to apply, and then go down step by step.
It is not easy to complete a transaction with a mobile phone. It has certain limitations, because the operator is not a bank, it does not have a license for financial operations, so the fee it can charge is a certain, small ceiling every month, so that it can not meet the payment needs of consumers. .
Security is a top priority
Lu Shaozu analyzed that mobile payment is currently handled according to some existing security issues that have been discussed. For example, pay with the card, before the payment is the background and POS machine for security, because there is a POS opportunity to communicate, mutual recognition process, after the POS machine to confirm the card is not safe, the chip content is not safe Will it be easy to be stolen, etc. This part requires third-party authentication before it can be applied to ensure that its entire link is safe. The mobile payment that is now talked about is just placing the terminal device in the mobile phone for payment, which is not much different from the POS machine.
Maru Takeshi analysis, non-contact application development, such as RFID applications can be radiated to the trading platform, transportation and wireless applications of security chips, and in this respect, international manufacturers are working hard according to their respective advantages. In the smart card space, Samsung's high-capacity advantages, Philips' contactless applications and Infineon's security-led solutions are highly competitive. In the smart card platform competition, Renesas will combine the flash controller with the SIM controller in the future to win the high-speed MCU core and large capacity.
Renesas has a small-capacity RFID chip u Chip, which has applications in electronic tags and electronic ticketing. Maru Takeo pointed out that it is very difficult to expand the RFID application in the smart card field in China, because in the whole smart card field in China, the competition is very fierce. At present, it can only start in developing new processes and reducing costs to ensure market share. As China's huge demand market, we should think about how to enter a benign development situation, and expand more market development such as security and micropayment.
Cost is still the bottleneck
At present, similar RFID contactless cards are used in bank cards and e-passports. It is not easy to destroy such applications because they have a high level of encryption guarantee, but at the same time the price is not at the same level as ordinary RFID. .
Infineon sources said that the cost of RFID technology is related to the actual application. Depending on the size of the antenna attached to the metal substrate, the number of productions varies greatly. In the case of a typical shipment of one million, the cost of embedding RFID is about 50 cents. However, such a situation will change in the next two to three years, and it is expected to reach about 20 cents in 2007, of which about 50% is the cost of the chip and the other half is the cost of the antenna and substrate material. The cost is related to the size of the antenna and the quality of the foil or attachment.
RFID is difficult to achieve low cost and high security. Industry experts point out that if you want to make RFID prices lower and lower, you should consider a wide range of basic applications. According to chip size, performance, cost and other factors, the security will be slightly reduced. The key to RFID lies in the scope of application. Experts point out that if you want the chip to have high security, if you are willing to pay the price of 1 US dollar or 2 US dollars, then the manufacturer does not mind. In fact, there are similar chips in use. The key is to look at which part of the application is more important and to choose between safety and price.
