In recent years, the market environment of the communications industry has undergone tremendous changes. The trend of internetization of communications services has become more and more obvious. The telecommunication networks are increasingly channelized and telecommunication services are becoming increasingly virtualized. Companies without a network can provide more services through the use of network channels. The more communication services, the traditional telecommunication operators rely solely on providing simple voice and data communications to gain profit more and more difficult to continue, and have to transition to “information services.”
On the other hand, with the rapid development of electronic technologies, more and more functions have been integrated into mobile phones, such as media broadcasting, games, photography, and navigation. Mobile phones have become more than just a communication tool, but have increasingly become a personal synthesis. Entertainment and information terminals.
How to expand the functions of mobile phones, in addition to the traditional communication through mobile networks, mobile phones can also serve the informatization applications such as mobile e-commerce, Internet of Things, and media advertisements that operators want to enter. This is the focus of research in the field of mobile communications in recent years. Among them, mobile phone RFID technology has achieved breakthrough results and began commercial use.
Mobile phone RFID technology integrates the RFID chip in a mobile phone or mobile smart card (SIM/UIM) to integrate the functions of the mobile phone and the RFID function. The user can use the mobile phone to achieve many applications such as financial services, shopping consumption, car service, and identity authentication.
Since the mobile phone-based RFID technology is not supported by the telecom operators, this paper will mainly study the implementation plan, application status, existing problems, and development trends of mobile smart cards that integrate RFID radio frequency functions (hereinafter referred to as mobile phone RFID smart cards). .
2 Mobile RFID smart card mainstream solutions
At present, the mainstream mobile phone RFID smart card solutions at home and abroad can be divided into two categories according to the operating frequency, that is, the 13.56 MHz scheme and the 2.4 GHz scheme. Among them, the 13.56MHz scheme can be further divided into eNFC scheme, dual interface card self-contained antenna scheme, and dual interface card handset customization scheme. The following describes four kinds of mobile phone RFID smart card solutions.
2.1 eNFC solution
The eNFC solution integrates RF RF antennas and radio frequency communication control functions into mobile terminals, stores RFID data storage and data processing functions on mobile smart cards, and communicates between cards and mobile phones through the SWP protocol to integrate RFID and mobile phones.
