KeyboardKeyboard
Keyboard is the oldest and most familiar of all input devices.
Keyboards are intelligent devices and contain their own chips.
A standard keyboard is called as a QWERTY keyboard because of the arrangement of letters of the top row of the alphabet keys.
There are invented special keyboards for the disabled and visually-impaired users keyboard.

Barcode systems are now at an advanced stage and readers can record barcodes at distances of 5 metres or more.

Optical Mark Recognition (OMR)Optical Mark Recognition (OMR)
Optical Mark Recognition (OMR) is used to sense marks made on a special form in certain places.
Uses of optical mark readers include multiple choice answer sheet marking, capturing data from questionnaires and enrolment forms and the checking of football pools coupons and so on.
But people who have never completed optical mark reading sheets can have problems filling them in.

The advantages are the use of OMR is that details do not have to be typed in and reduces the cost of inputting large volumes of data. Besides it is useful and very quick.
The disadvantages are being filled in by the general public then very clear instructions are needed and if the forms are folded then they maybe rejected by the machine.

Magnetic Stripe Cards Magnetic Stripe Cards
You can see magnetic stripe readers at the side of computerised tills (often called as electronic point-of-sale (EPOS) terminals).
It shows one being used to read information contained in the magnetic stripe of a credit card.

Optical character recognition (OCR) is a method of inputting text using a scanner along with special software to turn the scanned image into the standard ASCII code.
In other words, the text is no longer treated as a picture, since each individual letter is recognised on its own and can therefore be edited using word processing software.
OCR can be used to scan financial documents such as company accounts directly into spreadsheets, as well as to scan text directly into wordprocessors.
