The document discusses RFID (Radio Frequency Identification), its components, types of tags, and applications. RFID uses radio waves to automatically identify objects. A basic RFID system consists of RFID tags/inlays containing a chip and antenna, readers, and application software. There are three main types of tags: passive (derive power from reader), semi-passive (contain batteries to power chip), and active (powered by batteries). Current applications include access control, asset tracking, supply chain management, payment systems, and vehicle identification. The document also surveys small businesses on their opinions of RFID and its future potential in areas like healthcare and libraries.

3. 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

4. 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

5. RFIDTAG
 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

6. TYPES OF RFIDTAGS
ActiveTags
• Use a battery
• communicate over
distances of several meters
Semi-passiveTags
• 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
PassiveTags
• Derive their power from
the field generated by the
reader
• without having an active
transmitter to transfer the
information stored
