RFID, or radio-frequency identification, is a technology that uses radio waves to electronically identify objects. An RFID system consists of RFID tags attached to objects, RFID readers to interrogate tags, and an application system. There are three main types of RFID tags: active tags with internal batteries, semi-passive tags with batteries to power the chip, and passive tags that derive power from RFID readers. The document discusses applications of RFID in various industries and benefits such as enhanced customer satisfaction, improved efficiency, and reduced costs. Potential issues with RFID discussed include higher costs compared to barcodes and interference from some materials.

3.  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

4.  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

5.  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

6. Active Tags
• Use a battery
• communicate over
distances of several
meters
Semi-passive Tags
• Contain built-in batteries
to power the chip’s
circuitry, resist
interference and
circumvent a lack of
power from the reader
signal due to long
distance.
• They are different from
active tags in that they
only transmit data at the
time a response is
received
Passive Tags
• Derive their power from
the field generated by
the reader
• without having an active
transmitter to transfer
the information stored

13.  In medical uses and library management

15.  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
