Barcode Reader

What -A barcode reader (or barcode scanner) is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Additionally, nearly all barcode readers contain decoder circuitry analyzing the barcode's image data provided by the sensor and sending the barcode's content to the scanner's output port.

Where - Supermarket

When - Scanning Products

MICR

What – Magnetic Ink Character Recognition, or MICR, is a character recognition technology used primarily by the banking industry to facilitate the processing of cheques. The technology allows computers to read information (such as account numbers) off of printed documents. Unlike barcodes or similar technologies, however, MICR codes can be easily read by humans.

Where - Bank

When – reading cheques

OMR What- Optical Mark Recognition (also called Optical Mark

Reading and OMR) is the process of capturing human-marked data from document forms such as surveys, tests and questionnaire

Where – Anywhere (school, company etc.) When – marking examinations

OCR What- Optical character recognition, usually abbreviated to

OCR, is the mechanical or electronic translation of images of handwritten, typewritten or printed text (usually captured by a scanner) into machine-editable text.

Where- office and company When- converting paper books and document into electronic

files also to computerize and old record keeping system in an office or to serve on a website

Magnetic stripe What-A magnetic stripe card is a type of card capable of

storing data by modifying the magnetism of tiny iron-based magnetic particles on a band of magnetic material on the card. The magnetic stripe, sometimes called a magstripe, is read by physical contact and swiping past a reading head. Magnetic stripe cards are commonly used in credit cards, identity cards, and transportation tickets.

Where- anywhere ( shopping mall , supermarket etc.) When –paying money

Joystick What- A joystick is an input device consisting of a stick that

pivots on a base and reports its angle or direction to the device it is controlling. Joysticks are often used to control video games, and usually have one or more push-buttons whose state can also be read by the computer. A popular variation of the joystick used on modern video game consoles is the analog stick.

Where- Games shop, Home , Aircraft, Cranes, Trucks When- Playing Games (Play station and Computer), controlling

Where- Laptop and mobile phones (blackberry etc.) When- moving the pointer on the screen

Pin Pad What-A PIN pad is an electronic device used in a debit or

smart card-based transaction to input and encrypt the cardholder's PIN. PIN pads are normally used with integrated point of sale devices in which the Electronic Cash Register (ECR) machine is responsible for taking the sale amount and initiating/handling the transaction

Where- shopping mall ,supermarket etc. When- paying money using credit card

Light Pen What-A light pen is a computer input device in the form of a

light-sensitive wand used in conjunction with a computer's CRT TV set or monitor. It allows the user to point to displayed objects, or draw on the screen, in a similar way to a touch screen but with greater positional accuracy. A light pen can work with any CRT-based display, but not with LCD screens, projectors and other display devices.
