This document discusses wireless technology and radio frequency identification (RFID). It is divided into sections that cover the components of an RFID system, different types of RFID tags, applications of RFID technology in various industries, the results of an online survey on RFID use among small and medium enterprises, potential future developments of RFID, and a concluding video. It aims to provide background information and an overview of RFID technology.

4. RFID
 RFID = Radio Frequency Identification
 Electronic labeling and wireless identification of objects using radio
frequency
 Tag carries with its information
 a serial number
 Model number
 Color or any other imaginable data
 When these tags pass through a field generated by a compatible
reader, they transmit this information back to the reader, thereby
identifying the object

5. RFID COMPONENTS
 A basic RFID system consists of these components:
 A programmable RFID tag/inlay for storing item data;
 Consisting of an RFID chip for data storage
 an antenna to facilitate communication with the RFID chip
 A reader/antenna system to interrogate the RFID inlay
 Application software and a host computer system

6. RFID TAG
 The RFID tag consists of an integrated circuit (IC) embedded in a thin
film medium.
 Information stored in the memory of the RFID chip is transmitted by
the antenna circuit embedded in the RFID inlay via radio frequencies,
to an RFID reader
 3 types
 Passive
 Semi-passive
 Active

18. CONCLUSION
 Positive
 RFID is a contactless reading technology and can read through other materials
 Hold more data than barcode does
 RFID tags data can be changed or added
 More effective, bring lots of convenience to us
 Negative
 Cost is relatively remain high (compare to barcode)
 RFID signals may have problems with some materials
 RFID standards are still being developed
