Automatic identification and data capture

Object identification and data capture (AIDC) are techniques of autonomously recognising items, gathering information about them, and putting that information directly into computer systems without the intervention of a person. QR codes, bar codes, radio frequency identification (RFID), biometrics (such as iris and face recognition systems), magnetic stripes, optical character recognition (OCR), smart cards, and voice recognition are examples of technologies that are often regarded as part of AIDC. AIDC is sometimes referred to as "Automatic Identification," "Auto-ID," and "Automatic Data Capture," among other terms.

An example of AIDC is the process or method of gathering external data, typically via the analysis of photos, sounds, or videos. To collect data, a transducer is used, which turns the real picture or sound into a digital file that can be stored on a computer. The file is then kept so that it may be processed by a computer or compared with other files in a database at a later time in order to authenticate identification or grant authorisation to access a protected system. Data collection may be accomplished in a variety of ways; the most effective option is determined by the application.

When it comes to biometric security systems, capture is the process of obtaining and distinguishing features such as a finger image, palm image, face image, iris print, or voice print, all of which need audio data, while the others all require video data to be acquired and distinguished.

In comparison to other AIDC technologies, radio-frequency identification is a relatively young technique that was originally developed in the 1980s. The technology serves as the foundation for automated data gathering, identification, and analysis systems around the globe. Because of its capacity to monitor moving things, RFID has gained popularity in a broad variety of sectors, including livestock identification and Automated Vehicle Identification (AVI) systems, among others. These automated wireless AIDC systems are useful in production areas where barcode labels would not be able to withstand the conditions.
