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

Bar Codes



Smart Card vs Magnetic Strip

Well established
read/write technology

Low to medium storage
capability

Low cost data carrier
media and supporting
hardware

Range of security
developments,

Reasonably durable
materials

Contact read equipment

Growth area

Medium to high data
storage capabilities

Relatively low cost cards
and read technology

Read/write and
processing technology

Contact or close
proximity (contactless
cards) read


Enhanced security
capabilities and
encryption

Optical Cards

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
of data

Gives the ability to store graphical images
such as photographs, logos, fingerprints,
x
-
rays.

Electronic Article
Surveillance (EAS)


T
echnology used to
identify items as they
pass through a gated
area.


Used to alert someone of
the unauthorised removal
of items from a store,
library, or data centre.


Radio frequency
identification (RFID)

Tracking and access applications 1980s.

Enable non
-
contact reading

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.

RFID

Key Attributes and Limitations


Growth area of AIDC

New generation, lower cost transponders
offering multi
-
read capabilities

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
storage capability

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.

Utilizes battery
-
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.

(OCR)

Optical Mark Recognition (OMR)

Voice

Machine Vision

Magnetic Ink Character Recognition
(MICR)
