Abstract: Currently the RFID (Radio Frequency IDentification) systems become
used in many areas, especially for delivery, manufacturing, and maintenance of
goods. For example, a tag reader or a tag interrogator communicates with tags
attached on goods, reads their identification codes, and accesses their related
database through a network infrastructure. This approach makes it easy to
maintain goods very efficiently in large-scale markets, delivery systems, and
so on. There are many research activities in RFID systems for industrial
applications, but there is few on mobile and portable devices such as cellular
phones and PDAs. This paper presents an architecture overview of a
multi-protocol RFID reader on mobile devices with detailed description of
hardware implementation. We have considered several design parameters, such as
low power consumption, cost effectiveness and flexibility. Also, since our
architecture supports WIPI (Wireless Internet Platform for Interoperability),
any WIPI application can use our RFID reader's functionalities to query tags'
information from Internet through HAL interfaces. We prototyped our system on
the ARM-based Excalibur FPGA with iPAQ PDA, and also a chip with 0.18~um
technology for verification of our architecture.
