Automatic Identification and Data Capture (AIDC)

Aim of AIDC

At their core, all AIDC technologies support two common goals:

To eliminate errors associated with identification and/or data collectionTo accelerate the through-put process

Types of AIDC Technologies

Card TechnologiesData Communications TechnologiesBar Code TechnologiesRadio Frequency Identification TechnologiesEmerging Technologies

Card TechnologiesSmart cardsOptical cardsMagnetic Stripe

Other technologies can be put on cardsTouch memoryNew technologies - Dye Diffusion Thermal Transfer (D2T2) enable direct to card printingBar Codes

Smart Card vs Magnetic StripWell established read/write technologyLow to medium storage capabilityLow cost data carrier media and supporting hardwareRange of security developments, Reasonably durable materialsContact read equipment

Growth area Medium to high data storage capabilitiesRelatively low cost cards and read technologyRead/write and processing technologyContact or close proximity (contactless cards) read Enhanced security capabilities and encryption

Optical CardsUse 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)

Technology 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 LimitationsGrowth area of AIDCNew generation, lower cost transponders offering multi-read capabilitiesRead/write electronic storage technologyWide range of products satisfying a range of data storage and data transfer needsLow to reasonably high (64Kbits) data storage capabilityWide range of data transfer ratesRemote and close proximity readingRobust 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.
