Bar code software
Now-a-days, all wholesale
as well as retail goods are labeled by
using bar codes. Even small retail items
such as pencils or chocolates are
labeled with unique bar codes for
accurate identification. Barcodes
specify particular symbols and can be
identified by spacing between each bar
and the width and height of each bar.
Each bar could represent only character
data, alphanumeric data or numeric data,
based on the symbol used.
For the data to be read
precisely by the scanner, each bar code
has one start bar and end bar. A few
barcodes have an extra bar
in the end which is referred to as
checksum barcode. After the sum is
calculated by the scanner, accuracy is
checked with the checksum barcode’s
value. This reduces the probability of
the occurrence of an error and also
ensures that the calculations have been
carried out precisely.
Barcodes can be read with the help of
barcode scanner. A bar code scanner is a
photo sensor which converts each bar in
the barcode into an electric signal
based on its height, width and spacing.
The electrical signals are then measured
with the help of software that converts
these signals into legible characters
are recognising them. The software of
the scanner then transmits the readable
data to computer terminal. This entire
process in takes place very quickly,
this is, in a couple of seconds.
The software being used for tracking bar
codes is an accurate one; it maintains
precise records of all the scanned bar
codes. This makes sure that the data
about the products that have been sold
is recorded by the software itself.
Since the data is recorded by the
software loaded in the computer, the
retrieval of data can be done without
any fuss. Moreover, since this process
is faster when compared to entering the
data manually, it not only saves time
but also works more efficiently.
Barcodes are very useful while tracking
the inventory for generating annual
reports. For the retailers, scanning
their goods is an efficient and time
saving process since the probability of
occurrence of errors decreases while
recording or calculating data. Shopping
malls and supermarkets find barcodes
extremely useful to look after consumer
needs in small time periods, rather than
making consumers wait in long queues
while entering the data into the PC
manually.
It is crucial to handle financial
matters carefully since even a slight
problem could lead to complexities which
take long periods to solve. Especially
in surgical and medical fields, it is
difficult when clerical errors are
committed when inventory is taken. The
usage of barcode software eliminates
this problem since the rate of error is
very low.
It is important that a business chooses
the best type of barcode so that the
critical errors as well as other
problems are minimised to a great
extent. Barcode scanners and the related
software are quite inexpensive in
comparison to the wages given to clerks.
Moreover, they are efficient, easy to
use and long-lasting and can be used for
all types of products. |
