Automatic Identification and Data Capture (AIDC) refers to the process of automatically identifying and collecting data about objects/goods, then logging this information in a computer. The term AIDC refers to a range of different types of data capture devices. These include barcodes, biometrics, RFID (Radio Frequency Identification), magnetic stripes, smart cards, OCR (Optical Character Recognition) and voice recognition.


Automatic identification or “Auto ID” includes the automatic recognition, decoding, processing, transmission and recording of data, extremely frequently through the printing and reading of data encoded in barcodes. Barcodes allow for quick, easy, and precise reading and transmission of data for objects that require to be tracked or handled. Barcodes can be printed directly on envelopes, packs, bottles, containers, boxes, books, folders and other paperwork, equipment, cards, and several other items for identification.

The development of Auto ID techniques, involving barcodes and the correlated printers, scanners, decoders, and software, has considerably improved the speed, effectiveness and accuracy of data collection and entry. Initial application of barcode scanning, which included retail point-of-sale, article tracking and inventory control, have been expanded to include additional innovative application such as time and attendance, work-in-process, quality control, sorting, order entry, document tracking, transport and delivery and controlling access to protected areas. These expanded systems have significantly increased efficiency by linking production, warehousing, distribution, sales, and service to management information systems on real-time basis. Therefore, chances to increase operational productivity and customer reaction have established for retailers, transportation and package delivery companies, manufacturers, wholesale distributors and service providers.
