4 Reasons to use laser barcode scanners
by Raj Barcode Barcode Equipment & printersBarcode scanners are ages old – quite ubiquitous. They are perfect mode of convenience in such modern life. Undoubtedly, it facilitates quick and feasible transaction – Just Scan and Pay avoiding the element of human error. This barcode scanners have become a common sight in the world of Retail Departments, Logistics Management, Inventory Rotation and Automobile sector – purely omnipresent.
Let’s take
a plunge and dive deep into to know why, today, these technologies have become
such an essential part in every Industry.
Laser
Scanners are highly effective and produce bright, sharp laser beams with an extraordinary
grade of accuracy and reliability.
High
quality laser scanners possess the quality to read and scan the barcodes even
under harsh lights or in low light conditions.
This makes
them feasible in use where the proportion and density of lights and space is
quite limited like warehouses or storage containers.
In
comparison to older CCD devices, laser scanners can clearly read the language
of barcodes though located several feet away. This application is of utmost
importance in retail sectors.
They can be
used when there is necessity of producing high density scans on very small box
or dot shaped barcodes, like the ones often found on tiny electronics or on any
perishable objects.
The faster
you can complete transactions, the lesser time they’ll stand in queue and quite
happier your customers will be. You have often experienced this at cake shop,
grocery stores, and super markets. You just need a barcode scanner to capture
and store the information without any human error.
To your
notice, barcode scanners also serves
the crucial purpose when large number of items are being shopped and bought.
Scanning from a certain distance or at particular angle can get it done
smoothly.
Whether you
have a store or a sky scrapping business model, laser barcode scanners are a
worth addition to your daily requirement. They are very well designed for industrial
purpose. They have multiple products with large no of batches. They can capture barcodes within milliseconds
and can persist falls and drops from a reasonable height.
How Barcode Scanner works
A Barcode scanner
is basically an optical scanner that can read printed barcodes and decode the
data and then send back to a computer. It usually comprises of three different
parts - illumination system, sensor, and decoder.
To be
specific, a barcode scanner first “scans” the black and white coloured designs
of barcode by illuminating over that code through a red light. This illumination is then converted into text
matching. Basically, the sensor behind the barcode scanner detects the red
illuminated light and generate a signal. This signal is further sent to
decoder. The decoder interprets the signal, validates the barcode using the
check digit, and then converts it into readable text.
This readable
text is then delivered to a computer software system through barcode scanner. The
computer software is basically the collection of all the information of an
entity, cost, number of items sold and returned.
Barcode
scanners are available in varied format depending upon the requirement of your
industrial sector. Due to its unique quality of reading from distant space and
zero human error, its usability has increased tremendously in every sector of
Industry.
Some notable points to consider for barcode scanners:
Barcode
scanners cannot read 2-D codes that are more dominant than 1-D codes. It also faces
trouble with 1-D barcodes because they’re poorly printed, low-contrast, distorted,
or damaged.
Laser Code
position is always fixed but with few exceptions, 1-D codes must be scanned
from left to right. Also, the scanning must be done consistently in one single
direction.
One of the
most considerable point is that Laser scanners are fitted with an oscillating
mirror. Any break in moving parts may add handsome costs or replacement
cost. To your concern, they must be
handled with care at the eye scanner area for users.
At first glance, all of this may seem quite convoluted but understanding
this will help you to trace and maintain your application smoothly. They enable quicker checkouts, a well-organized
inventory management system and highly observable promotional campaigns. Stay
