1. Automatic Identification And Data Capture
Technology

2. What is AIDC
•Automatic Identification and Data Capture (AIDC) is a broad category
of technologies used to collect information from an individual, object,
image or sound without manual data entry.
• Some of the technologies are Barcode, RFID, NFC, Biometrics and
many others
• These technologies aims at identifying an entity and ability to read and
process that identity

4. RFID :RADIO FREQUENCY IDENTIFICATION
•Radio-frequency identification (RFID) is the wireless non-contact use of radio-
frequency electromagnetic fields to transfer data for the purposes of
automatically identifying and tracking tags attached to assets.
• RFID is Fast and Reliable
• It does not require a physical line of sight or contact between reader and the
tagged item

5. COMPONENTS OF RFID:
 RFID Reader/Interrogator
RFID Tag/Transponder
RFID Antenna

6. RFID READER
• Brain of the RFID system
• Sometimes they are named as interrogator
• Transmit and receive radio waves in order to communicate with
RFID Tags
TYPES OF READERS
Fixed Reader Handheld Reader Integrated Reader

7. RFID ANTENNAS
•Antennas will allow the reader to transmit and receive signals
from the RFID Tags
• Antennas comes with various size, gain and polarization
•Gain – higher the gain, the more powerful the antenna. A higher
gain antenna will produce a larger field, thus extending read range
farther than a lower gain antenna.

8. LINEARLY POLARIZED CIRCULARLY POLARIZED
Broadcast electromagnetic waves on a
single plane
in a corkscrew-like fashion.
Horizontal plane/Vertical plane Right/Left hand circularly polarized
Greater read range Lesser read range
RFID tag must be fixed upon the same
plane as the antenna
RFID tag may be found in any
orientation
Polarization (horizontal) Circular Polarization (right-hand)

9. RFID TAGS
• it comprises of two parts antenna and a chip
• an antenna for transmitting and receiving signals, and an
RFID chip (or integrated circuit) which stores the tag’s ID
and other information.

Read Range: near contact - 10+ meters
Examples: Supply Chain, High-volume Manufacturing, Electronic
tolls, Item Tracking, Asset Tracking
Pros: longer read range, lower cost per tag, wide range of tag sizes and
types, global standards, high data transmission rates (read more tags at
one time)

hour or more, with near 100 percent reliability.
Cons: active RFID tags are powered by a battery so will
eventually require replacing

16. RFID TAGS- on chip Memory

19. Advantages of RFID System
•As no line-of-sight is required, tag placement is less
Constrained
•RFID tags have a longer read range than barcodes
•Tags can have read/write memory capability
•Many tags can be read simultaneously
•RFID tags can be combined with sensors
•Tags can locally store additional information; such
distributed data storage may increase fault tolerance of the
entire system,
• Reduces inventory control and provisioning costs,

20. APPLICATIONS
Document tracking/Library Management System:
Each document is tagged with a RFID tag and the document ID is
stored in DB, Personnel are also issued with RFID cards for issue and tracking
Readers are placed in entry/exit position and also at the issue desk and
dropdown box

21. • RTLS (Real Time Location Systems)
In some applications, you need to track the real-time location of assets,
employees, or customers. Whether you’re measuring the efficiency of
worker movements, the effectiveness of a store floor plan, or tracking
the location of valuable resources, RFID systems provide visibility in
any number of locations.

22. Automated Toll Collection
Electronic toll collection system allows the vehicle drivers to pass the
toll tax booths without stopping at the toll booths. The toll amount is deducted
from the RFID card. This RFID card is rechargeable and account is stored on the
records.

23. Attendance Tracking:
-helps to gather business intelligence at events like trade shows,
conferences, corporate functions, and other large gatherings.
-Attendee’s are given badges affixed with UHF RFID tags. Appropriately
placed RFID readers and antennas track the location of the RFID badges as
the attendee visits booths, seminars, product demos, and other events.

24. IT Asset Tracking:
-IT assets such as server blades, laptops, tablets, and other peripherals are
costly investments for any company, not to mention that information stored
on those items could prove detrimental in the wrong hands. IT asset tags
give your IT team the ability to quickly do an inventory count and make sure
everything is in place.

25. NFC – Near Field Communication
• It is a subset of RFID Technology
• It is a form of contactless communication between 2 devices
which uses RF waves
• operating frequency 13.56 MHz
• read range is about 10cm or less
• Supported data rates: 106, 212 or 424 kbit/s

26. Three Modes Of NFC
1. Card emulation mode: example e-payment
2. Peer to peer (Bluetooth like communication)
3. Reader/writer mode ex: advertisement (Smart Poster )

27. 1. Card Emulation Mode:
This mode enables NFC-enabled devices to act like smart
cards, allowing users to perform transactions such as purchases,
ticketing, and transit access control with just a touch.
Benefits
- Physical object elimination(Credit cards, debit cards, paper based
tickets, physical keys)

28. 2. Peer To Peer Mode:
Peer-to-peer mode enables two NFC-enabled devices to
communicate with each other to exchange information and share
files, so that users of NFC-enabled devices can quickly share
contact information and other files with a touch. For example, users
can share Bluetooth or WiFi link set-up parameters or exchange
data such as virtual business cards or digital photos.

29. 3.Reader/Writer Mode:
Reader/writer mode enables NFC-enabled devices to read
information stored on inexpensive NFC tags embedded in smart
posters and displays, providing a great marketing tool for companies.
In reader/writer mode, the NFC-enabled device is capable of reading
NFC Forum-mandated tag types, such as a tag embedded in an NFC
smart poster.

30. NFC Tags-On chip Memory
Tag Type On Chip Memory
MIFARE Mini 320 Bytes
MIFARE 1k 1024 Bytes
MIFARE 4k 496 Bytes
MIFARE Ultralight 192 Bytes
MIFARE Plus 2/4 Kb

31. Applications
NFC applications can be split into four basic categories.
Touch and Go
•Applications such as access control or transport/event ticketing, where the user
only needs to bring the device storing the ticket or access code close to the reader.
• simple data capture applications, such as picking up an Internet URL from a
smart label on a poster.

32. Touch and Confirm
-Applications such as mobile payment
-confirm the interaction by entering a password or just
accepting the transaction.
Touch and Connect
Linking two NFC-enabled devices to enable peer to peer
transfer of data such as downloading music, exchanging
images or synchronizing address books.
