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
