RFIDRFID = Radio Frequency Identification

Electronic labeling and wireless identification of objects using radio frequency

Tag carries with its informationa 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 componentsA 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 TagThe 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 TagsActive 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

ConclusionPositive

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
