RFID technology uses radio waves to electronically identify objects. It consists of tags that store data, readers that interrogate tags, and application software. There are passive, semi-passive, and active tags. Common applications include access control, asset tracking, supply chain management, and electronic toll collection. A survey found potential industries for RFID include document management, inventory control, library management, logistics, and security. Further development opportunities exist in medical and library uses. RFID provides contactless reading, stores more data than barcodes, and allows updating tag data, but costs remain higher than barcodes and signals can be blocked by some materials.

3. 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

4. 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

5. 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

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

15. 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
