Prepare a 2-3 page paper explaining the following:
· Accuracy of data input is important. What method of data input would be best for each of the following situations and explain why:
· Printed questionnaires
Keyboard; aside from avoiding uncertainty from unclear handwriting or other methods, and because "...most input data consists of letters and numbers. In addition, people are usually familiar with how to use keyboards and with the layout of the keys. Thus, little training is required for users to become familiar with keyboards"

Or an OMR or optical mark recognition.

· Telephone survey
Touch-tone (keypad) input. Also considered a keyboard by the text, so the cite still applies here for reasoning.

Or

voice recognition is best because a voice input device can be programmed to distinguish answers spoken into the receiver allowing it to all be completed by computers.

· Bank checks scanning devices that recognizes bar codes are called MICR (Magnetic Ink Character Recognition) a magnetic scanning input device. This system reads the numbers at the bottom of the checks and will mechanically make modifications to the correct accounts. A MICR input system will magnetize the information at the bottom of the check for simple interpretation.

Or

The best input for bank checks would be MICR (Magnetic Ink Character Recognition) a magnetic scanning input device. Because banks have to deal with large volume of checks they need a system that can read checks fast. This system reads the numbers at the bottom of the checks and will automatically make adjustments to the proper accounts.

Retail tags bar code scanner. This is called an optical scanning input device. By using a bar code scanner manual input of numbers into a keypad is not necessary.

· Long documents

Scanner , OSR(Optical character recognition)

· Convenience and quality of output
