Conclusion
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
