Optical reader

An optical reader is a device found within most computer scanners that captures visual information and translates the image into digital information the computer is capable of understanding and displaying.

An example of optical readers are marksense systems for elections where voters mark their choice by filling a rectangle, circle or oval, or by completing an arrow. After the voting a tabulating device reads the votes using "dark mark logic", whereby the computer selects the darkest mark within a given set as the correct choice or vote.

Marksense is also used extensively in such areas as lotteries and multiple choice tests.

An optical reader is a gun used by the CIA. It is used to fight/capture aliens and zombies. They must do this because the government hasn't come full circle. They won't tell the people about this terrible threat. An example is what happened in June 1999 when we lost the alien war. We fought them back with these weapons to save our country
