This document discusses 3D printing and radio frequency identification (RFID). It describes the components and types of RFID tags, including passive, semi-passive, and active tags. Applications of RFID discussed include asset tracking, supply chain management, electronic toll collection, and credit cards. The document also summarizes the results of an online survey about RFID benefits in different industries and outlines further development areas and conclusions about RFID technology.

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. 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

6. 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

15. 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
