RFID uses radio waves to automatically identify objects. It is used widely in supply chains to reduce costs through improved tracking and coordination. RFID tags can store more information than barcodes and be read from a distance without line of sight. Common applications of RFID include use in libraries to track books, in warehouses for inventory management, in healthcare for tracking patients and equipment, and in livestock farming for animal identification.

1. RFID and Applications
RFID or Radio-frequency identification
•is the use of wireless non-contract system that use radio-frequency electromagnetic
fields to transfer data from a tag to a receiver.
•The automatic identification and data gain the large contribution to many
companies bottom line. The RFID is one of the most wanted technologies that
usually appear in the large successful enterprises, such as Wal-Mart, Dell, food
stores, automobile part makers, computer stores, and even book stores.
•of RFID offers attractive avenues as to reduce the cost through coordination
between marketing and manufacturing across supply chains. It could improve supply
chain efficiency through real-time tracking, safety monitoring, and overall
warehouse operations, which the results leads to increase in sales volume and
improving profitability for suppliers and retailers.

2. How it work
• It emitted as two-way radio transmitter receivers
which the readers send a signal to the tag and read its
response .
• The information stored electronically in a non-volatile
memory. This possibly will be an unique tag serial
number, or product related information
• Tags may either be read-only which factory assigned
serial number that is used as a key into a database, or
may be read/write where object-specific data can be
written into the tags by the system user

3. RFID type
• Active RFID : have on-board battery and
frequently transmit its ID signal
• Passive RFID: does not require the
battery, which it much cheaper and the
size of it can be small
RFID Active Tag RFID Passive Tag

4. RFID and Barcodes
• The barcode has become a component that
could easily be found on the product that you
buy.
• The barcode is the ubiquitous standard for
identifying and tracking products.
• The system was based on the ink pattern that
glowed when exposed to ultraviolet light,
proved to be unstable in practice to be
commercialized

5. The advantages of RFID
• Each RFID tag could have an unique code that allow every
tagged item to be individually
• RFID allows for information to be read by radio waves from
a tag without requiring line of sight scanning or human
intervention
• RFID allows for virtually simultaneously and instantaneous
reading of multiple tags
• RFID tags can hold far greater amounts of information
which can be updated
• RFID tags are far more durable

6. RFID Application
Library System : The technology use the passive
tags instead of active tags. The tags that use in
the facility requires a very short read range
and the data that stored on the RFID tags does
not reveal any important information
The information that usually recorded on the
RFID will be the ‘book name’, ‘author of the
book’, ‘date of publishing’, ‘unique
identification number’

7. Warehouse System & Supply chain :
• The technology can be used to identify, track,
sort or detect a wide variety of objects. The
data of tags can change or add new
information always
• The main objective of these was to reduce the
cost and increase it efficiently on working
process such as substitute on the paper-based
work.

8. Healthcare : The technology are used for
tracking people or items in a facility, locating
staff or instruments in a hospital, keeping
track of patients in care facility.

9. Card Technology : The technology used wireless
computer chip and antenna based and contactless
smart-card technology in order to identity the specific
information of each credit card.
• The credit card is designed specifically for easy
integration into the existing payment-authorization
infrastructure. The technology are fast, easy, often
more reliable than magistrate transactions
• The RFID credit technology is absolute security and
privacy

10. Animal Identification : The microchip implant is an
identifying integrated circuit which placed under
the skin of animals .
Each chip ID will consist of owner contact
information
• The farm management system involve in fully
automated process such as feeding, weighing,
disease management, and breeding practices.
Each ear tags that be used in livestock have
conform international standards ISO 11784 and
ISO 11785
