"Stickers" are very widely
used when an object requires identification
with a word or idea.
stickers may be attached to products to
identify those products as coming from a
certain company. They may also be used to
describe characteristics of the products
that would not be obvious from simple examination.
They are frequently distributed as part
and political campaigns; for example, in
many voting districts in the US, stickers
indicating an individual has voted are given
to each voter as they leave the polling
place, largely as a reminder to others to
vote. Other methods of underground forms
of voting for your favorite graffiti artists'
current productions are by an open form
of appreciation such as clapping while passing
such a sticker (a smile and a kind reminder
to a fellow appreciater throughout the day
is common place as well).
Stickers placed on automobiles, called
bumper stickers, are often used by
individuals as a way of demonstrating support
for political or ideological causes. Identification
of vehicle registration and last service
details are two examples of stickers on
the inside of most car windscreens.
Barcodes are frequently used on many
products as a convenient way of identification.
