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. RFIDTAG
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

6. TYPES OF RFIDTAGS
ActiveTags
• Use a battery
• communicate over
distances of several meters
Semi-passiveTags
• 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
PassiveTags
• Derive their power from
the field generated by the
reader
• without having an active
transmitter to transfer the
information stored

13. 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
