THE TRACKING OF PRODUCTS
THIS INVENTION relates to the tracking of products. More
particularly, this invention relates to a method of detecting designated
products and to a system for detecting designated products.
According to a first aspect of the invention, there is provided
a method of detecting designated products from a number of sources,
the method including the steps of
applying an unique code to each one of a plurality of products at a first location;
determining which of the plurality of products become designated;
recording the codes of the designated products;
reading the codes of products distributed at a second location;
and
comparing the read codes with the recorded codes to determine if
any of the distributed products are designated products.
It will be appreciated that the term "designated products"
includes products that are stolen, products that are lost by undetermined
means and picked up as lost through stock taking or other methods of
reconciling numbers of products, products not intended for re-sale to
consumers, sample batches of products, defective products, products
sold to a Government sector, export products, imported products, or the
like. "Products" is also meant to include three-dimensional articles and
other articles such as cheques, tickets or the like. Designated products
which are detected may then be recovered. It will be appreciated that
the method and system may also be used as an audit system for keeping
track of designated products, in particular, for products not intended for
re-sale.
The codes of the designated products may be determined by
retaining a first list of the unique codes which are applied to the products
at the first location, and comparing it to a second list of codes of
products which are decoded at another authorised location, with the
codes which appear on the first list and not the second list comprising
the codes of the designated products.
The codes of the designated products may be recorded at
a central loss control station. The method may include transmitting the
read codes to the central loss control station, for comparing the read
codes with the recorded codes.
The method may also include transmitting data on the
identity of the second location and data on the time at which the read
codes are transmitted to the central loss control station.
The method may include triggering an alarm at the central
loss control station if designated products are detected to alert a person
on duty. The data may also be visually displayed at the central loss
control station in such a way that it alerts a person on duty.
A record of the data and the read codes may be retained at
the central loss control station if the products are designated products.
According to a second aspect of the invention, there is
provided a system for detecting designated products from a number of
sources, the system including
an encoding means for applying an unique code to each one of a
plurality of products at a first location;
a designated products determining means for determining which
of the plurality of products become designated;
a recording means for recording the codes of the designated
products;
a reading means for reading the codes of products distributed at
a second location; and
a comparator for comparing the read codes with the recorded
codes to determine if any of the distributed products are designated
products.
The comparator may be located at a central loss control
station. The codes of the designated products may be retained in a
database of the comparator at the central loss control station.
The system may include a transmitting means for
transmitting the read codes to the comparator at the central loss control
station. The transmitting means may also transmit data on the second
location to a central loss control station.
The first location may be a manufacturing plant, with the
codes being applied to manufactured products on an assembly line.
Alternatively, the first location may be a warehouse for imported
products or for export products.
The second location may be a retail outlet, with the reading
means forming part of a bar code scanning system. Alternatively, the
second location may be a retail outlet, with the reading means being in
the form of a free-standing or hand held scanner suitable for use by a till
operator or an independent user of the system.
It is to be appreciated that the system is not limited to use
with retail products or products earmarked for re-sale.
The invention is now described, by way of example, with
reference to the accompanying drawing which shows a schematic flow
chart representing a system, in accordance with the invention, for
recovering designated products.
In the drawing, reference numeral 1 0 generally indicates a
flow chart representing a system, in accordance with the invention, for
recovering designated products.
The system includes an encoding means 1 2 for applying an
unique forgery resistant code to each one of a plurality of manufactured
products. The encoding means 1 2 is located in a manufacturing plant
1 4, with a code being applied to each product on an assembly line. The
code may be in the form of a forge-resistant mark such as a hologram.
The manufactured products are transported from the plant
1 4 to the premises 1 6 of a distributor, who, in turn, supplies the
products to an end retail outlet 1 8 where they are sold to the public.
It will be appreciated that the manufactured products can
reach the end retail outlet 1 8 though different routes. Some of the
manufactured products may be stolen or otherwise designated from the
plant 14, from the premises 1 6 of the distributor, or at any stage when
being transported from the plant 14 to the premises 1 6 or the retail outlet
1 8. The stolen or designated products land up with an unauthorised
distributor at a venue 20 through any one of routes 1 9. The unauthorised
distributor sells the products and they may also be distributed through
the retail outlet 1 8.
The quantity of manufactured products is checked by the
distributor when the products are received at the premises 1 6. If the
quantity received does not tally with the quantity of manufactured
products dispatched by the manufacturer, the distributor knows that
some of the products have become designated products. The distributor
receives a list of codes applied to the manufactured products and a
decoding device from the manufacturer to determine the codes of the
designated products. The quantity of manufactured products may also
be checked at the retail outlet 1 8 in the same way or at any other stage,
if theft is suspected.
A recording means 22 for recording the codes of designated
products is located at a central loss control station 24. The codes of the
designated products are supplied to the central loss control station 24
where they are entered into the recording means 22 which is in the form
of a database.
A reading means in the form of a scanner 26 for reading the
codes of distributed products is located at the retail outlet 1 8. The
control station 24 includes a comparator 28 for comparing the read codes
with the recorded codes to determine if the products are designated
products. The read codes are transmitted to the station 24 on a daily or
more regular basis.
In use, all of the distributed products located at the retail
outlet 1 8 are scanned at point of sale or on the shelves. The comparator
28 at the station 24 compares the read codes with the recorded codes
to determine if any of the distributed products are designated products
which have been received by an unauthorised route or dealer. If it is
determined that the distributed products are designated products, data
is retained at the central loss control station 24. The data includes the
codes of the detected designated products, the identity of the second
location and the time of the reading. The data are visually displayed at
the central loss control station in such a way that it alerts a person on
duty. The person on duty will act on the information in an appropriate
way, for example, by alerting the police. A record of the data is
maintained at the central loss control station 24 for evidence purposes.
The inventors believe that the invention has several
advantages. Firstly, a central database of designated products is
established. Also, designated products are accurately marked by each
having an individual code which can be identified in a simple operation.
Further, accurate records of the process are available for possible criminal
prosecution.
