2. AIDC Technologies Automatic Identification and Data Capture (AIDC)

3. 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-put process

4. Types of AIDC Technologies • Card Technologies • Data Communications Technologies • Bar Code Technologies • Radio Frequency Identification Technologies • Emerging Technologies

5. Card Technologies • Smart cards • Optical cards • Magnetic Stripe Other technologies can be put on cards • Touch memory • New technologies - Dye Diffusion Thermal Transfer (D2T2) enable direct to card printing • Bar Codes

6. Smart Card vs Magnetic Strip • 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 • 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

7. 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.

8. 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.

9. 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.

11. 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

12. 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.

13. Other methods of AIDC • Biometric Identification • Contact Memory • Optical Character Recognition (OCR) • Optical Mark Recognition (OMR) • Voice • Machine Vision • Magnetic Ink Character Recognition (MICR) • http://www.aimglobal.org/technologies/othertechnologies/
