AUTOMATIC IDENTIFICATION
AND DATA CAPTURE

WHAT’S IN THIS PRESENTATION


What Is AIDC?


Why should we use AIDC technologies?


Overview of different AIDC technologies


Some future developments of AIDC



WHAT IS AIDC?


A way to identify and collect information about a
particular object


Use the information to perform various actions with a
computer system


Main reason is to do all of this without human support


WHY HAVE AIDC?


Severely cuts down on human labor


Manage information


Track information


Organize, deliver goods more efficiently


Handle a bigger volume of goods


Better security


Personal ID capabilities


AIDC TECHNOLOGIES


Barcodes


RFID


Biometrics


Magnetic Strips


OCR


Smart Cards


Voice Recognition


EAS


RTLS

BARCODES


Have been around for more than 50 years!


The standard for today’s tracking of products


Two types of barcodes today:


One dimensional





Two dimensional


RADIO
-
FREQUENCY IDENTIFICATION (RFID)


Uses radio waves for communication


Will soon replace barcodes completely


Most RFID tags consist of two parts


Circuit


Antenna


Some require their own power source, some are powered by the scanner.


Example: Protecting babies

BIOMETRICS


Used for identifying people


How it works


Two modes for biometrics:


Verification


Identification



EXAMPLES OF BIOMETRICS


http://
www.youtube.com/watch?v=OPwOJbNAB2g&feature=relmfu


The Nigerian Bank savings account ID

MAGNETIC STRIPS


Usually found on cards that contain the familiar black stripe


Cards that typically have the black stripe:


Credit/debit cards


ID cards


Library cards


Usage of these cards:


Access badges


ID cards


Key cards

HOW A MAGNETIC CARD READER WORKS


Magnetic card stores information in three separate tracks


Each track contains different bit densities and character sets


Track 1


210 bits per inch. 64 bit character data set.


Can hold 79 characters


Track 2 and 3


75 and 210 bits per inch respectively. Only numeric data can be stored.


Can hold 40 and 107 characters respectively


Actual usable data stored minimized as the Start Sentinel, End Sentinel, and LRC


Data storage format is as follows:


Leading zero bits are encoded for synchronization purposes for the reader.


The Start Sentinel then presents its actual data


Then the End Sentinel follows with its actual data and then terminates the data portion


The LRC is a byte used for error detection and follows the End Sentinel and zero bits fill the remaining card


HOW A MAGNETIC CARD READER
WORKS
CONTINUED


The magnetic card reader can read and handle all three tracks simultaneously


The card reader also has an oscillator section that uses timers for enabling and disabling.
These timers provide the ability for the reader to lock onto the data and recover individual
data bits from the data stream on the card.


Simple card reader programs read the card in a forward direction. More complex
programs can read the card in any direction
.

OPTICAL CHARACTER RECOGNITION (OCR)


Process in which scanned images or text get translated to machine encoded
text


Typically used to convert books into electronic files.


OCR abilities:


Edit text in documents


Search for words/phrases in documents


Some OCR systems can also reproduce images or other non
-
text
components like borders

SMART CARDS


Smart card = advanced credit card


Contains a microprocessor. Used to replace the
magnetic stripe of a card


Widely used in Europe


More secure than ID cards


Have up to 8 kb of RAM


Not self
-
powered

WHY SMART CARDS OVER MAGNETIC STRIPS
OR OTHER IDENTIFICATION CARDS?


The Moroccan Driving licenses

VOICE RECOGNITION


Main objective: convert spoken words into text


Uses an analog
-
to
-
digital converter


Translates voice vibrations to data


Runs through a database to match phonemes to data


Outputs what the computer thought the person said

ELECTRONIC ARTICLE SURVEILLANCE (EAS)


Most commonly used in department/grocery stores


Think of those gates near the doors of most
department/grocery stores


Uses RFID technology


REAL TIME LOCATING SYSTEM (RTLS)


Comes as a fully automated system


Uses RFID tags and a networking system


Multiple systems working together


Continuously sending location data to main server


Example: Luther college in Iowa

FUTURE DEVELOPMENTS OF AIDC


New RFID developments



Becoming less costly and better performance


Memory capacity is being increased


New powering devices


Global positioning tracking sensors being reduced to 10cm across


Using AIDC technologies, University of Michigan has developed a chip for testing for the
flu. Other Universities are branching off and developing chips for HIV and cancer
screening.


A company in Japan has developed two types of thermal rewritable paper

LASER SURFACE AUTHENTICATION (LSA)


Invented by Professor
Russel

Cowburn

at the Imperial College in London


Low cost laser data capturing system


Can uniquely identify:


Documents


Currency


Passports


Licenses


Art


Makes counterfeiting products a lot harder to do

CONCLUSION


Benefits are intangible


Clear signs of growth


Becoming a standard in business today
