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

Further Development

• In medical uses and library management

Video

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
