Symbol Bar Code Scanner
Traditionally, barcodes encoding schemes
represented just numbers, newer symbologies added new
characters such as from the upper case alphabet to the
complete ASCII character set and beyond. The drive to
encode ever more information in combination with the
space requirements of simple barcodes led to the
development of matrix codes, which do not consist of
bars but rather a grid of square cells.The use of
barcode scanner is widespread and the technology behind
barcodes is constantly improving. Some modern
applications of barcodes include:
- Items purchased from a grocery store, department
store and mass merchandiser. This greatly helps in
keeping track of the large number of items in a
store and also reduces instances of shoplifting.
Since the adoption of barcodes, both consumers and
retailers have profited from the savings generated.
- Rental car companies keep track of their cars by
means of bar codes on the car bumper.
- Airlines track passenger luggage with barcodes,
thus reducing the chance of loss.
- Researchers have also placed tiny bar codes on
individual bees to track the insects' mating habits.
- NASA relies on bar codes to monitor the
thousands of heat tiles that need to be replaced
after every space shuttle trip.
- The movement of nuclear waste can be tracked
easily with a barcode inventory system.
There are many companies offering a barcode package
which includes a bar code printer for the labels,
hand-held scanners, and the necessary software for both
the scanners and your computer system. The savings
resulted from just the reduced labor cost often make
physical inventory barcode implementations a worthwhile
investment. But a word of caution: as bar codes are
assigned to bins, all of your products must be located
in their proper locations. Don't attempt a barcode
physical inventory unless your warehouse is in order.
