Radio-frequency identification (RFID) technology has proved to be very effective in anti-counterfeiting and logistics management. It is widely regarded as one of the most important sensing technologies for Internet of Things (IoT). As IoT becomes the next important revolution for information technology following personal computer and internet, RFID technology is now being applied in more industries. Recently, significant cost reduction of RFID tag has removed the biggest obstacle for RFID technology's wider adoption. Another important trend is that widely available smartphone is now considered as the converged device for IoT applications. The factors above inevitably drive the development of a new product, i.e., a smartphone with RFID reader capability or IoT smartphone. Now IoT smartphone is gradually used for smart transportation, smart logistics, asset management, anti-counterfeiting and mobile payment. Some design houses also start to promote their IoT smartphones in the market. The rise of IoT smartphone is calling for miniature multi-frequency RFID reader module with high performance. Current market available High Frequency (HF) and Ultra High Frequency (UHF) RFID reader modules are big in size, and their RF performance is easily affected in different environments. Also, smartphone design houses have to optimize the antenna design on their own, and there is no present solution to achieve the data protection for RFID readers. This not only makes the actual development becoming difficult and time-consuming, but also limits the possible applications of IoT smartphone. Therefore, our project aims to develop a miniaturized dual-frequency RFID reader System-in-Package (SiP) with Near Field Communication (NFC) functions for smartphone. Based on the developed methodology and algorithm in the seed project, we will implement tunable RF matching system and proprietary power saving solution in the to-be-developed SiP. Most importantly, to further reduce the form factor and improve the performance for smartphone integration, three major technical challenges will be resolved in this full project as below: (1) To achieve ultra-small form factor of SiP and also obtain good signal integrity, a novel sandwiched 3D SiP with core partitioned hybrid substrate will be developed. (2) To consume space as small as possible and also meet performance criteria, a tunable dual-frequency antenna (NFC coil antenna plus UHF loop antenna) fabricated on the flexible substrate will be developed. (3) To protect RFID reader system against unauthorized access such as malicious smartphone apps, an embedded data security mechanism will be developed.
