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
