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

Further Development
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
