Taiwan bans invisible-ink pens from exams
To
prevent students from cheating during school exams, Taiwan on Monday
banned the use of invisible-ink pens.”We will bar students from using
invisible-ink pens during exams because many students are cheating with
these pens,” Lee Yu-Chuan, from the Education Ministry’s Higher
Education Department, told a news conference.Since an invisible-ink pen
uses fluorescent ink, a student can write invisible notes on a piece of
paper and take the paper to the exam. During the exam, he or she can
then read the notes by shining the ultraviolet flash — which is at the
other end of the pen — onto the paper. The notes become visible when
they are exposed to ultraviolet light.Education authorities in many
countries, including China, have banned students from using
invisible-ink pens during exams to prevent cheating.An invisible-ink
pen is sold for 200 Taiwan dollars ($6)
