Data Capturing through AIDC Technology

Automatic Identification and Data Capturing (AIDC) is a technology that automatically identifies the objects, collects the related data, stores and enters the data directly into computer systems. AIDC is also known as Automatic Identification or Auto-ID or Automated Data Capture. In the majority of cases Automatic Identification and Data Capture (AIDC) systems work without the interference of human and if in case it requires human involvement then that may be a user scanning an AIDC equipped item that is barcoded and it will have the ability to enter data electronically into computer systems.

The information associated with the object is called identification data. This data may be in different forms like images, voice or finger prints. This data will be converted into a digital file before typing the data into computer system. Hence, a transducer is used in order accomplish this task means for converting the original data into digital file. The stored data file is analyzed by a computer or is compared with other files in a database after entering the database into computer system in order to provide access for entering into a secured system.

  • Data encoding – In this the alphanumeric characters will be translated into the form that can be read by machine.
  • Machine scanning – The machine scanner reads the encoded data and converts the data into electric signals.
  • Data decoding – The electrical signals will be transformed into digital data which later converted into alphanumeric characters.

Different Types of AIDC Technologies for Data Capturing:

Various Automatic Identification and Data Capturing (AIDC) technologies are as follows:

  • Barcodes
  • Radio Frequency Identification (RFID)
  • Biometrics
  • Magnetic Stripes
  • Optical Character Recognition (OCR)
  • Smart Cards
  • Voice Recognition
  • Electronic Article Surveillance (EAS)

Barcodes will be scanned originally by special optical scanners called barcode readers. A Barcode is an optical machine which is a readable representation of data or information and the information which the Barcode contains is about the object which is attached to the barcode. We will see bar-coded items in Supermarkets. Barcode reader uses a laser beam and the reader translates information from the image to digital data and sends it to the computer.

Barcode is called as UPN/EAN. The very first scanning of the Universal Product Code (UPC) Barcode back in 1974. Barcodes consist of small images of lines or bars affixed on many items in order to identify a particular product number, person or location.
Examples of Barcode in use today are UPC/EAN, Code 39, Code 93, Code 128 and Interleaved 2 of 5.

Barcode technology standards define:

  • Reading and decoding techniques
  • Rules for measuring the quality of printed/marked symbols
  • Rules and techniques for printing or marking
  • Rules for representing data in an optically readable format

Radio Frequency Identification (RFID):

Radio Frequency Identification

Radio Frequency identification (RFID) is a technology that uses radio waves to transfer data between a reader and an electronic tag which is attached to a particular object. This technology used in data collection and identification. A Radio Frequency identification (RFID) is mainly used for object identification and tracking. Without making direct contact with the item, the RFID obtains information on an item. An RFID system consists of three components – an antenna, a transceiver and a transponder (the tag).

Biometrics:

Biometric Technology

Biometrics is typically involved in the identification of a person and it compares captured biological data with the stored data of that individual. Biometrics system consists of a scanning device or a reader with software which converts the scanned biological data like finger prints into digital format. If an individual uses a biometric system for the first time they have to enroll the biometric information. This biometric information is detected and compared with the information stored at the time they enrolled into the system. Fingerprint recognition, face recognition, Palm print recognition and iris recognition are the typical types of Biometric systems used within the world of AIDC.

Magnetic Stripes:

The magnetic stripe is also known as swipe card and it is read by swiping magnetic reading head. Magnetic stripe technology will be used for security purposes. Magnetic Strips were found on a Magnetic Stripe Card and it is capable of storing data by modifying the magnetism of small iron-based magnetic particles on a strip of magnetic material. They provide standards for bank cards, credit cards, IDs, ATM cards etc including the allocation of card numbers. These magnetic stripes contain information about the owner of the respective card. The information in magnetic stripes is read by magnetic stripe reader. The first magnetic stripe cards were used in the early 1960s on transit tickets and in the year 1970s for bank cards.

Optical Character Recognition (OCR):

Optical character recognition uses technology similar to the one used for CD ROMs. Optical Card Panel is gold colored laser sensitive material that is laminated in the card and the material react when a laser light is directed at them. Optical Card is the electronic or mechanical translation of scanned images of text which were typewritten or handwritten or printed into machine encoded text and it is used to convert books or documents into electronic files. The standards for optical cards can be obtained from ISO.

It checks mail based payments by credit cards to computerize and text on website. It is also used to digitize documents. OCR helps in pattern recognition and artificial intelligence. The optical card stores 4 and 6.6 MB of data that gives ability to store graphical images such as photographs, logos, x-rays, fingerprints, etc.

Smart Cards:

Smart Card Technology

A smart card is an integrated circuit card (ICC) and it is a pocket-sized plastic card which has a small chip attached and contains an integrated circuit. It is an electronic recording device. Smart cards provide strong security authentication in large organizations, they stores data and when necessary those records can be transmitted to a central computer. Most smart cards looks like a credit or debit card, but smart cards can function on at least three levels (credit-debit-personal information). These smart cards are capable of data storing, for providing identification and application processing.

Voice Recognition:

Voice Recognition or Speech Recognition is simply a task of translating the spoken words of that particular person and it converts the spoken words to text. It is a technology that can recognize speech. Voice recognition include voice user interfaces such as voice dialing, call routing, search, simple data entry, preparation of structured documents, domestic appliance control, speech-to-text processing, etc.

Electronic Article Surveillance (EAS):

Electronic Article Surveillance (EAS) is a technology used to identify items as they pass through a gated area when you enter into any showroom in malls or library. This technology is used to alert the unauthorized persons from taking the items from a store, library or museum and other important places. Theft can be encountered with this technology. RFID and some other types of Electronic Article Surveillance (EAS) systems are used inside the technology of Electronic Article Surveillance.
