Introduction
Automatic Identification and Data Capture (AIDC) refers to technologies that help in automatically identifying objects, collecting data about them, and entering that data directly into computer systems. Technologies that fall under AIDC include barcodes, Radio Frequency Identification (RFID), biometrics, Optical Character Recognition (OCR), and more.
Historical Context
AIDC technologies have evolved significantly since their inception. The concept started gaining traction in the mid-20th century with the invention of barcodes in the 1950s. Since then, the industry has seen tremendous advancements, particularly with the development of RFID and biometric technologies.
Types/Categories
Barcodes
Barcodes are optical, machine-readable representations of data. They are commonly used in retail for tracking inventory.
RFID (Radio Frequency Identification)
RFID uses electromagnetic fields to automatically identify and track tags attached to objects. It does not require line-of-sight and can work over greater distances than barcodes.
OCR (Optical Character Recognition)
OCR technology converts different types of documents, such as scanned paper documents, PDFs, or images taken by a digital camera, into editable and searchable data.
Biometrics
Biometric systems use unique biological traits such as fingerprints, retina patterns, or facial recognition to identify individuals.
Key Events
- 1952: Introduction of the first barcode system.
- 1970s: Development of RFID technology by Mario Cardullo and others.
- 1980s: Commercial adoption of OCR in banking and other sectors.
- 1990s: Significant advancements in biometric technologies.
Detailed Explanations
RFID Technology
RFID systems consist of tags, readers, and software. The tag contains a microchip and an antenna, while the reader sends out an electromagnetic signal. When a tag passes through this signal, it transmits data back to the reader.

OCR Technology
OCR technology involves scanning a document and then analyzing the text within the image. It is highly accurate and fast, making it ideal for digitizing printed documents.
Importance and Applicability
AIDC technologies are crucial in numerous industries:
- Retail: Inventory management and tracking.
- Healthcare: Patient identification and medication tracking.
- Logistics: Supply chain management and asset tracking.
- Banking: Automated cheque processing with OCR.
Examples
- Supermarkets use barcodes to scan and price products quickly.
- Hospitals use RFID wristbands for patient identification.
- Banks employ OCR for quick cheque deposits through ATMs.
Considerations
- Data Security: Protection against unauthorized data access.
- Accuracy: Ensuring high accuracy to avoid errors.
- Cost: The expense associated with implementing AIDC systems.
