How much does it cost to buy a barcode scanner that has a database of
and can display prices for all the products in a shop? How sturdy are
such scanners, and how long will they last when subjected to the
normal abuse and carelessness of the general public? How is the
database of such barcode scanners updated? How can it be ensured that
the database in the scanners is the same as the database used by the
tills?
