Description: 有关RFID的资料!adio Frequency Identification Device (RFID) has been getting a ton of coverage in the press ever since Wal-mart stated that they were going to require their suppliers to tag products. Over the past few years, the ability to use RFID has gotten not only cheaper, but also easier to use. By the end of this article, you'll see just how easy it has gotten to implement a passive RFID system that hooks into your applications. I use C# and .NET in my example, but you could also use Java or several other languages to do the same thing.

Description: Radio Frequency Identification [RFID]
systems have become popular for
automated identification and supply chain
applications. This article describes the
technical fundamentals of RFID systems
and the associated standards. Specifically,
we address the security and privacy aspects
of this relatively new and heterogeneous
radio technology. We discuss the related
security requirements, the threats and the
implemented mechanisms. Then the current
security and privacy proposals and their
enhancements are presented. Finally we
discuss the role of this technology in
Ubiquitous Computing-The automated identification of objects
with electromagnetic fields is the major
purpose of the RFID [Radio Frequency
Identification] technology. An RFID system
basically consists of transponders [tags],
readers [scanners] and application systems
for further processing of the acquired data.
There is a large variety of different RFID
systems: they may use low, high or ultra
high frequencies, the transponder may emit
only a fixed identifier or possess
significant memory and processing
capabilities. Transponders may incorporate
no security features at all or realise
effective security protocols similar to
smartcards. Most transponders are
passively powered by the radio field
emitted by the reader but there are also
active tags with a separate power supply.
The transponder design is also little
uniform: there are e.g. tiny tags with a size
of several millimetres, very thin “smart
labels” or standard ID-1 cards

Description: The attendance system is basically an embedded one.The microcontroller plays an important role in the system.
The main objective of the system is to uniquely identify and to make attendance for a person. This requires a unique product, which has the capability of distinguishing different person. This is possible by the new emerging technology RFID (Radio Frequency Identification). The main parts of an RFID system are RFID tag (with unique ID number) and RFID reader (for reading the RFID tag). In this system, RFID tag and RFID reader used are operating at 125KHz. The EEPROM used for storing the details has the capability of storing 256 person details at a time. The PC can be used for restoring all the details of attendance made.
This report provides a clear picture of hardware and software used in the system. It also provides an overall view with detailed discussion of the operation of the system.
