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

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

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

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

Types of industries that respondents think it is possible to apply RFID technology

In medical uses and library management

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
