Active Tags
Passive Tags
Semi-passive Tags
• communicate over batteries to power the from the field
distances of several chip’s circuitry, resist generated by the
meters interference and readerwithout having
circumvent a lack of an active transmitter
power from the to transfer the
reader signal due to information
long distance.
• They are different
from active tags in
that they only
transmit data at the
time a response is
received

8. 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

9. 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

10. 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

20. 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
