Magnetic-ink character recognition (MICR) technology is used by the banking industry for faster processing of the large volume of cheques. This technology also ensures accuracy of data entry because most of the information is pre-printed on the cheque and is directly fed to the computer. 13. A digitizer is an input device used for converting (digitizing) pictures, maps and drawings into digital form for storage in computers. This enables re-creation of the drawing from the stored information whenever required as well as easy incorporation of changes in the drawing as and when required. 14. Electronic cards are small plastic cards having encoded data appropriate for the application for which they are used. An electronic-card reader, which is normally connected to a computer, is used to read the data encoded on an electronic card and transfer it to the computer for further processing. 15. Depending on the manner in which data is encoded, electronic cards are of two types - magnetic strip cards and smart cards. Magnetic strip cards store the data to be encoded on a magnetic strip attached to the back oi the card. On the other hand, smart cards have a built-in microprocessor chip and the data to be encoded or the card is permanently stored in the memory of the microprocessor chip. 16. Voice recognition devices are input devices that allow a person to input data to a computer system b) speaking to it. They are basically of two types - speaker-dependent and speaker-independent. Speaker-dependent systems can recognize the speech of only a single individual or a few individuals. On the other hand, speaker-independent systems can recognize words spoken by anyone. 17. A vision-input system allows a computer to accept input just by seeing an object. The input data in this case is normally an object's shape and features in the form of an image. 18. Online data entry involves input devices, which are connected directly to the computer, whereas offline data entry involves...
