Definitions

  • the present invention relates to the monitoring of transactions relating to articles, essentially in retail stores. It relates more precisely to a process and an installation for monitoring transactions which are intended to defeat most frauds, by implementing simple means.
  • the customer changes the labels placed on articles so that, on reading, the billing relates to an erroneous article.
  • a method and an apparatus for identifying articles which largely prevent this type of fraud.
  • the patent of the United States of America No. 3,681,570 describes an installation in which the articles are transported automatically first in front of a reader which reads coded information and determines not only the price but also the gross weight of the article, then on a weighing device which measures the actual gross weight. The article is then transported in a container. All these operations are automatic and the comparison of the gross weight read on the information and the measured gross weight makes it possible to avoid fraud in which labels are exchanged on articles of different gross weights.
  • the invention relates essentially to these monitoring operations, making it possible to avoid the main effects of fraud and applying essentially to manual systems, that is to say in which the operations are executed by the client who is therefore always at proximity to items.
  • this monitoring is also suitable for systems in which one or more operations are executed automatically.
  • the invention is based on the measurement of overall weights, that is to say the weight of a cart containing at least one item, throughout the execution of a series of transactions, on at least an article.
  • the invention provides additional and essential security by confirming the transactions only when the essential operations have been carried out in the proper order. More specifically, a transaction is only confirmed when it has been determined that reading the information, giving a gross reference weight, has indeed preceded by the determination of the measured gross weight obtained by difference between the overall weights determined after and before the article is deposited in a receptacle, for example a trolley.
  • This security is further increased when a similar operation is carried out before reading, that is to say when an initial gross weight is determined by difference between the total weights of a container before and after the removal of an article. , preceding the reading.
  • the method then comprises, before reading the information affixed to each item, the separate removal of each item from the container and the determination of an initial gross weight by difference between the overall weights before and after removal of the item, the compa reason for the gross weights then comprising the comparison of at least one of the three gross weights with each of the other two, the confirmation of the transaction being carried out only when the picking of the article preceded the reading of the information.
  • the container and the receptacle are placed on two separate weighing devices, the determination of the initial gross weight being carried out by difference between the total weights given by a weighing device before and after removal of the article, and the determination of the gross weight measured being produced by difference between the overall weights given by the other weighing device, after and before the article is deposited.
  • the operations of removal, presentation to a device for reading and depositing each item are carried out manually, preferably by the buyer.
  • the display of information indicating that a transaction has been validated and confirmed is also advantageous because it then indicates to the buyer that he can move on to a next item or that he can indicate that the series of transactions is completed. .
  • the installation comprises two weighing devices, one on which the container is placed and the other on which the receptacle is placed.
  • the initial gross weight is determined by the difference between the overall weight signals of one of the weighing devices, and the measured gross weight is determined by the difference between the overall weight signals of the other weighing device.
  • a second transaction is only validated when the determination of its initial gross weight has started after the determination of the reference gross weight of the previous transaction.
  • Each of the two weighing devices 10, 12 comprises a plate 16 disposed at ground level, this plate preferably having two lateral rails 18 intended to guide the wheels of a carriage 20 of the type commonly used in this type of store; many scales are already known having plates of this type. It is therefore not described in detail.
  • sensors 22 suitably arranged and preferably four in number, permanently give a combined signal which represents the instantaneous weight of what is placed on the plate.
  • These weighing devices are well known and the particular type indicated above, comprising four sensors 22, preferably torque gauges, makes it possible, by difference, to compensate for the offset of the load on the plate 16 so that the weighing is always exact.
  • the weighing signal is suitably processed so that it gives the necessary precision.
  • the overall weight given by the weighing device is known to the nearest 20 g, the weighing being carried out in 3000. points with a range of 60 kg. These values can be obtained with relatively inexpensive and very reliable weighing devices currently available commercially.
  • the second weighing device can also be replaced by a bag support in which the customer places his purchases, the support being mounted on a scale. Such a device reduces the stabilization time of the weighing.
  • the intermediate reading device 14 can be of different types. It may for example be an analysis device moving a reading beam over the code of the article. Since these conventional analysis devices have a relatively low recognition rate, it is desirable to use a holographic type analysis device which has a recognition rate fairly close to 100%. However, given the cost of this device, it is preferable, in less expensive installations, use an array of diodes near which the customer places the code or a light pen. These devices require a little more handling on the part of the buyer, but they have the advantage of greater reliability and their use does not require significant learning.
  • the installation further comprises a microcomputer 24 having a memory 25 and intended to perform all kinds of operations described in the following of this memory, according to the overall weight signals from of the two weighing devices 22, of the read signal, and of other signals which can be transmitted by the buyer from simple push buttons 26, for example when a series of transactions is completed, when a transaction must be canceled, etc.
  • a display device 28 of well-known type, for example with light-emitting diodes, is advantageously placed near the reading device 14, that is to say in front of the buyer when he performs the various operations .
  • microcomputer 24 manages the various operations described above and controls the output devices, the most important of which are an alarm system 30, intended to indicate non-validable operations, the aforementioned display device 28, and a device 32 editing an invoice.
  • step 52 the computer checked in step 52 that the overall weight of the first weighing device had not yet varied by removing an item. Then, in step 54, he checked that no read operation had been performed. In step 56, he also checked that the second weighing device had not yet given a significant difference indicating the placement of an article. Consequently, the computer successively executes the loop of steps 50-52-54-56-50 as long as no article has been picked up in one carriage or placed in the other.
  • the buyer stands in front of the desk and then grabs, for example, with the left hand a first item in the left cart.
  • the computer detects at step 52 a significant variation in the overall weight and determines the gross weight of the article taken from the first cart, at step 58. Then it waits until the reading has been taken. The buyer who has just taken the item passes it under the reading device. As long as the reading has not been carried out, the computer describes the loop 60-62, the step 62 corresponding to the determination of the fact that the overall weight of the second carriage has not varied significantly.
  • the computer goes to step 64, that is to say it determines, as a function of the code read, what is the gross reference weight, by consulting the memory 25.
  • the computer prepares to determine the second gross weight, that is to say the gross weight determined when the article is placed in the second carriage.
  • the computer prepares to determine the second gross weight, that is to say the gross weight determined when the article is placed in the second carriage.
  • the computer describes the loop of steps 66 and 68, step 66 corresponding to the determination that the overall weight of the second carriage has varied significantly, and step 68 corresponding to a measurement of time, l computer verifying that the time that has elapsed since the reading has not exceeded a certain value.
  • this verification loop implementing a clock, can be associated with the operations described above.
  • step 66 When the computer has determined in step 66 that the second overall weight had presented a significant variation, it determines the second gross weight in step 70. Then, in steps 72 and 74, it successively compares, two by two, the two gross weights of the two scales and the reference weight obtained by reading. When the comparisons give significant values, the computer validates the transaction, in step 76, and records a partial invoicing in step 78. The operations then return to step 50, the computer determining whether the end of transaction series button has been pressed. When this button has actually been pressed, the computer goes to step 84 which corresponds to the printing of the final invoice and to the end of the series of operations for this client. Then, the installation goes to the start step, this start being triggered by an operation such as the arrival of a new full trolley on a tray, etc.
  • the buyer can, for example, wait, before leaving with the cart containing his goods, for a "flying" cashier ", alerted for example by the lighting of the warning light 32, to collect the amount of the invoice
  • a cash register where he pays the amount of his purchases.
  • This cash register can be very close or it can only be separated from the billing item by a very short or very clear space allowing easy monitoring.
  • the computer 24 determines that the reference gross weight differs from at least one of the other two measured weights, it prevents the validation of the transaction and controls the alarm device, at step 80, after the execution of the step 72 or step 74.
  • the continuation of operations, including in particular the stopping of the alarm device, requires reordering by the surveillance personnel, indicated by step 82.
  • step 56 determines in step 56 that the second weighing has given a gross weight while the reading has not been carried out beforehand, as indicated in step 54.
  • the computer therefore automatically proceeds to the procedure d alarm of step 80.
  • the buyer can take simultaneously two articles in the first cart, for example a bottle of current wine and a bottle of fine wine, and have the information of the bottle of current wine read and then place the bottle of fine wine in the second cart.
  • the buyer then hopes to repeat this operation by taking a bottle of fine wine in the first cart and putting it in the second while redoing the bottle of wine running in front of the reader.
  • the installation does not allow such fraud since it determines, in step 58, that the gross weight of the two removed items does not correspond to the gross weight read in step 64 on the first item, and the transaction is therefore not not validated, the alarm device being controlled.
  • the above installation has a very high security due to several characteristics.
  • the first is the comparison of a measured gross weight with a reference gross weight read directly on the article, this operation being already known.
  • the second is the continuous observation of the overall weight of the articles involved in the transactions. Indeed, the reduction in weight of the first carriage must correspond to the increase in weight of the second carriage, after deposition. The overall weight must therefore always be constant, except between the withdrawal and the deposit of an article.
  • the determination of the fact that the sequence of operations is carried out in the correct order picking-reading-deposit gives additional security. This can be further increased by using various timers, as shown by way of illustration with reference to step 68 of the flowchart in Figure 3. Security can be further increased when the sample must not precede the deposit of the previous article.
  • This type of installation lends itself very well to the habits of customers who often have personal belongings in the carts.
  • the installation automatically takes into account this tare change.
  • a signal can also be transmitted to the surveillance personnel under these conditions so that they can observe the regularity of this different tare.
  • the two safety characteristics according to the invention can be obtained, that is to say, in addition to the comparison of a measured gross weight to a reference gross weight, on the one hand the regular variation of the overall weight of the receptacle and secondly the determination of the proper order of operations, by using a single weighing device carrying only one carriage, the second or the one which is filled.
  • this installation is not advantageous when no auxiliary device is opposed to various manipulations that the buyer can attempt.
  • the latter can take a first article from the first cart, have it read, then put it back in the first cart and pass another article directly from the first to the second cart, this second article having the same gross weight as the first but of course another price.
  • the invention can be implemented with a single weighing device which carries only one carriage.
  • One of these additional devices may for example be an ultrasonic device comprising a transducer associated with the reader's head and emitting ultrasound at the time of reading.
  • the ultrasound returned makes it possible to determine the density of the reference article and the microcomputer can then determine whether this density corresponds to the nature of the article indicated by the information affixed.
  • microcomputer can itself contain all the information necessary for determining the gross weight from the information read, but it can also be linked to a central installation which includes a regularly updated file. These are characteristics well known to those skilled in the art and which are therefore not described in detail.
  • the installation described has a large number of advantages. Since it does not require staff, each store can have as many billing stations as necessary so that customers do not experience excessive waiting. Due to the lack of staff, all billing stations can still be in service.
  • the operations carried out by the customer are simple and do not require more time than the current operations of invoicing by a cashier with reading by an automatic device.
  • the articles are always under supervision given the implementation of the method according to the invention, the buyer always has them under surveillance: given the implementation of the method according to the invention, the buyer always at hand and reassured.
  • the realization of the installations is not expensive since it requires only a small number of devices themselves inexpensive and already existing in large quantities.
