• the commercial in-store sales sector suffers from several types of loss of profits, known as the "Undiscovered” or DI.
• the DI is divided into three parts:
• the anti-theft tags are not effective against internal theft because employees have direct access to crates and unlocking or deactivation systems.
• the antitheft badges are formed of two parts, part of which is a nail, the management of these two parts unlocked and separated proves painful for the store staff, including the boxes where the badges are unlocked.
• Video surveillance is also not effective enough to combat internal theft because of relatively small video surveillance staff, large numbers of people to watch in department stores, and blind spots. cameras can not reach.
• Vigils are unreliable and can only monitor a limited number of people.
• the aforementioned systems are not effective in the case of substitution by a malicious person of a price tag of an article with that of another article and when a cashier scans an article at a low price and sells, to a person of his choice, one or more higher priced items.

• the identifier TID of the device 20 is read. This read information is then transmitted to the terminal 14 which thus finds in the server or the database 16 the corresponding association TID-EAN uniquely identifying the commercial item / the physical object.
• the single commercial item code EPC is used (this code uniquely identifies a physical object as a commercial item and can therefore be used in place of the TID-EAN association for this item. unique identification) that is stored in a volatile memory area of the antitheft device (EPC zone) different from the area where the TID code (TID area) is written. The reading of the EPC zone is faster than that of the TID zone.
• This information read (by an appropriate device) is then transmitted to the terminal 14 which thus finds in the server / database 16 the corresponding association TID-EPC (or EAN).
• the QR code is used carried by the device 20 and read by a suitable device.

• the locking members can completely obstruct access to the housing, take other forms and for example form a single locking member (single door in the manner of a flap), or more than two organs.
• the mechanism of movement of the locking member (s) may differ from that explained with reference to FIGS. 2 and 4.
• peripheral portion 40 surrounding the mechanical stabilizer and its housing 30 may be fixed, while said mechanical stabilizer and its housing are able to move between a high unlocking position and a low locking position.
• the decoupler may comprise, in addition to the means already described, extraction means which facilitate the extraction of the second element from its housing. It may for example be a member or pushing finger which is arranged in the stabilizer 31 and which is adapted to deploy on command to push up the second element.
• the free end of the extraction member has a slope or cam shape adapted to the outer profile of the body of the second element (eg spoon shape) in order to come into contact with it and to cause it to rise out of the house.
• such a variant may alternatively replace the displacement of the peripheral portion 40 or the stabilizer 31.

• the decoupler 12 is freely accessible to the devices 20.
• the article to which is attached a device 20 is set by the customer to the payment terminal 14 before or during the unlocking action.
• the device 20 is thus brought to the decoupler, read past the reading device 29 and introduced into the housing of the decoupler.
• the mobile peripheral portion 40 of the decoupler is in the upper locking position. Unlocking the device 20 occurs automatically and the article is released, but the second member 24 remains blocked inside the housing by the locking members 70, 72.
• These organs are activated to deploy in the opening of access to the housing and thus prevent axial withdrawal of the second element, as the same first element has not been returned to the decoupler. It ensures in fact that it is the same first element that is used to extract the second element. The second element is thus released as for the previous embodiment.
• the management method comprises several steps S'1, S'2, S'3 and S'4 which are carried out in place of the steps SO to S8 and which register before payment steps S9 to SU. Then, the steps S12 to S26 already described for the management of the unlocking of the device 20 to prevent fraud and improve the management of the two separable elements constituting the device apply.
• the user has a mobile or portable communication device 200 (FIG. 26) such as a smartphone or smartphone.
• This apparatus is equipped with a screen 202, an Internet browser and a software application for reading optical codes such as the QR optical reading code mentioned above.
• the application is previously downloaded via the Internet to the device 200 and launched by the user.
• step S'1 the user who is in front of the physical object 210 is invited to read (and decode) the QRl optical code of the antitheft device (or identification 20).
• the optical code By aiming the optical code with the camera of the device it scans the image of the code and proceeds to its decoding.
• the application securely connects to the memory zone ZI of FIG. 17 and interrogates the table T1 from the decoded QR1 code character string, which makes it possible to uniquely and securely identify the physical object / relevant article and the store.
• the QRl code is linked to the code TID1 (step S'2). If no article / TID is identified, the step S'2 is followed by the step S'1 already described.
• the user is identified from the communication of a user name and password via his device and he then has access to his user account. Otherwise, it is not identified and a user account must be created by filling in all the appropriate information allowing to carry out a commercial transaction online (personal details? Means of payment).
• the next step (S'3) then provides for establishing an Internet connection between the device 200 and one or more URL addresses dedicated to the article or in relation thereto (complementary articles), namely here the URL3 address.
• This link with the URL is made possible because of the association table T1 that links TID1, QR1 and URL3 (Association 1).
• the user is then automatically directed to this address and is thus connected with the site or page 212 hosted on a server 214 which is not necessarily the server 16 of FIG. 1A (it should be noted that the optical code does not incorporate a script that points directly to a URL address because the connection with the URL is only allowed after completion of the above-mentioned steps).
• This page brings up a window 216 on which the affected article of the article code EAN3 is displayed.
• the code TID1 is thus associated with a commercial article via its code EAN3. If it is not the case, the step S'3 is followed by the step S'1 already described.
• the user can perform various actions from his device 200 (obtaining additional information, storage in a selection list 218 for a deferred action such as a deferred purchase, online or not, placement / selection of the article identified by the association TID1-EAN3 in a shopping cart 220 with a view to its immediate acquisition .).
• step S'4 the user selects the article / object he wishes to purchase and validates this selection for online payment thereof via his device in subsequent steps S9 to SU.
• the transaction is carried out securely as on many websites.

• a dissociation (FIG. 17) between the optical code / TID and the URL / EAN corresponding to the article / object must be performed in order to reuse the newly unlocked device with other items / objects. It should ensure that a new article / object attached to the device will not be associated with an incorrect URL.
• This dissociation is recorded both in the tables T1 and T2 in order firstly to break the link between the different codes and addresses and secondly to keep a record of the dissociations as such with a view to subsequent use such as the billing of services associated with the multiple use of the same device 20.
• the erasure of the RFID chip of the device 20 is also performed in order to remove the TID-EAN link.
