Why is it necessary to stipulate that no correction fluid correction tape should be used in the secondary school and college entrance exams?

The computerized correction system for secondary and higher education exams makes it impossible for the computer to scan the words written on the correction tape if it is used.

Correction fluid is a white opaque pigment that is applied to paper to cover up typos and can be rewritten on it after it dries. Correction fluid is traditionally packaged in small bottles with a small broomstick or triangular shaped piece of styrofoam dipped in the fluid.

Correction tape is a white opaque pigment similar to correction fluid, which is applied to paper to cover up typos, and can be rewritten on it immediately, providing a convenient way to study and work. It was invented by Japan SEED Company in 1989. The main ingredients of correction tape are AS, PS, resin, titanium dioxide and so on.
