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
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
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
Types of RFID Tags
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

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
