UPC
barcode
labels were invented in the late 1940s but didn't really gain momentum
until the early 1970s when grocery stores started using
barcode
labels to make the checkout process speedier. Soon every industry from
retail to rental cars and chemistry labs to railroad stations were using
barcode
labels to keep track of their items.
It wasn't long before some disadvantages of the
barcode
labels started to reveal themselves. Since stores and companies depended
so heavily on the information tracking of the
barcode
labels, every time an item was added or removed, the
barcode
labels had to be scanned. Also a special person had to be hired just to
devise, track, and update the numbers on the
barcode
labels. This proved to be an unpleasant expense of
barcode
labels for some businesses. Also the technology of the
barcode
labels didn't keep up with the population and long lines are still a
problem since all
barcode
labels on every product need to be scanned before purchase.
It is now believed that radio frequency identification (RFID) tags may be
the future of retail product tracking and will someday replace UPC barcode
labels. RFID tags, also called smart labels, can "talk" to a network and let
the system know when you pick up something to buy and place it in your
carriage. No more lines, no more waiting that is so common with the old
barcode
labels. Unfortunately the day of RFIDs replacing
barcode
labels in still far in the future due to the expense and limited range
of the RFID tags available today. So for the time being the UPS
barcode labels that we have come to know will have to keep on working
for us. |
