Data Capture and
Aim of AIDC
At their core, all AIDC technologies
support two common goals:
To eliminate errors associated with
identification and/or data collection
To accelerate the through
Types of AIDC
Bar Code Technologies
Radio Frequency Identification

Contact or close
Use technology similar to the one used for
music CDs or CD ROMs.
Panel of the "gold coloured" laser sensitive
material is laminated in the card and is
used to store the information.
Can currently store between 4 and 6.6 MB
Gives the ability to store graphical images
such as photographs, logos, fingerprints,
echnology used to
identify items as they
pass through a gated
Used to alert someone of
the unauthorised removal
of items from a store,
library, or data centre.
Tracking and access applications 1980s.
Effective environments where bar code
labels could not survive.
Wide range of uses including livestock
identification and automated vehicle
identification (AVI) systems because of
its ability to track moving objects.
Key Attributes and Limitations
Growth area of AIDC
New generation, lower cost transponders
Read/write electronic storage technology
Wide range of products satisfying a range
of data storage and data transfer needs
Low to reasonably high (64Kbits) data
Wide range of data transfer rates
Remote and close proximity reading
Robust constructions available, allowing
use in reasonably harsh conditions
Real Time Locating Systems
Fully automated systems
Continually monitor the locations of
assets and personnel.
operated radio tags and
a cellular locating system to detect the
presence and location of the tags.
Deployed as a matrix of locating
devices that are installed at a spacing
of anywhere from 50 to 1000 feet.
Locating devices determine the
locations of the radio tags.
Other methods of AIDC
Optical Character Recognition
Optical Mark Recognition (OMR)
Magnetic Ink Character Recognition
