Abstract:
Embodiments of the present invention disclose an efficient and inexpensive method for detecting tampered products utilizing current off the shelf components. Features of some embodiments provide for a RFID labeling system that uses multiple RFID components attached to a single product unit being embedded in the product&#39;s label and one or more tamper labels. Such RFID labels usually comprise an adhesive label containing an RFID component, a destructible conducting path that acts as an antenna and a unique encryption. The RFID labels transmit the encryption when irradiated by an RF scanner. A complete inventory of multiple associated encryptions reported during an RFID scan of a product package provide positive indication that product has not been tampered with. A missing encryption indicates a faulty product seal or an event of tampering.

Description:
TECHNICAL FIELD  
       [0001]     The present invention relates to a system method and device to detect product tampering utilizing radio frequency identification (RFID) labels.  
       BACKGROUND  
       [0002]     The concept of inventory control and tamper proofing products utilizing radio frequency identification (RFID) is not new. The technology is used widely for consumer and pharmaceutical product inventory control and other purposes.  
         [0003]     However, a significant problem continues to exist in today&#39;s market which concerns the product liability risk surrounding the unknowing sale of a product with a broken tamper seal to a customer. Either the customer discovers the broken seal after purchase in which case he returns the product which increases product returns and shrinkage. Or worse, he commences a product liability lawsuit. Despite the fact that the customer may not even use the product, a sale with the broken seal opens the door for legal claims based on adulterated product. All reasonable attempts should be made to monitor product packages on the shelf to eliminate tampering after shelving or the acceptance inventory with broken seals in the first instance.  
         [0004]     The use of current RFID technology allows for the identification of products while the RFID transponder attached to the product is operating but once the transponder is disabled, the item becomes invisible to the scanner. Inventory control may detect the absence of an item because the RFID transponder no longer registers on the RFID scanner. Such a condition may falsely indicate shop lifting or that the store staff moved the product out of scanning range. The liability remains in that the tampered product may remain on the shelf and available for purchase.  
         [0005]     The manual process required by store personnel to inspect and detect broken product seals is time intensive and inefficient. Such inspection would have to be done at least daily by minimum wage employees. More seriously, individuals seeking to intentionally adulterate a product would attempt to cover the evidence of their acts. Such concealment would surely pass unnoticed by store employees. Therefore a need exists for a system to detect tampered products quickly, inexpensively and reliably.  
         [0006]     Another important field for the application of the current invention is in the medical field. Health care facilities utilize a plethora of medications that are administered to dozens of patients daily. Theft and tampering with medications is a persistent problem. Also, nursing staff currently deliver medications and either are required to stand by while the patient takes the medication or periodically must check to see if the medication has been taken. A need would arise to track medications and their usage after they are dispensed from the facility pharmacy.  
       SUMMARY  
       [0007]     Embodiments of the present invention address the above issues and others by providing an efficient and inexpensive method for detecting tampered products utilizing current off the shelf components. For example, features of some embodiments provide for a RFID labeling system that uses multiple electronic components such as RFID components. Such RFID labels are well known in the art and usually comprise an adhesive label containing an RFID component and a destructible conducting path or electronic circuit that acts as an antenna. The RFID component and antenna have the ability to transmit information stored on the RFID component to a scanning device when prompted by radio frequency energy transmissions from the scanning device. The stored information may also be simultaneously received by a plurality of scanning devices distributed throughout a facility allowing for locating the product by triangulation.  
         [0008]     Preferably, the RFID label is permanently attached to a product package or to the product itself by a strong adhesive such that any attempt to disturb the label destroys the RFID component or antenna and degrades the ability of the RFID component to transmit its information. A non-limiting example of such a label is fully described in U.S. Pat. No. 6,888,509 B2 by Atherton and is hereby incorporated by reference in its entirety although other versions and improvements are envisioned thereto and would not detract from the spirit and purpose of the present invention.  
         [0009]     Some RFID labels are attached to products by looping the label device through a product appendage and then adhering to itself. Such a RFID label method is disclosed by Atherton in US patent application 2004/0066296 A1 and is incorporated herein by reference in its entirety as an additional non-limiting example of a use for a tamper label or a product label. It would be evident to one skilled in the art that there may be variations and improvements in RFID and RFID label technology that would be useful for use in the present invention. Such incorporation is envisioned and would not lie outside the scope and spirit of the present invention.  
         [0010]     In one exemplary embodiment of the present invention that allows for product tamper detection, multiple RFID components may be embedded in multiple labels. One label may be the “product” information label. Other “tamper” labels may be utilized to seal the accesses in the product package. Each RFID component embedded in each of the labels may have a unique encryption recorded thereon that may be associated with encryptions on the other RFID components affixed to the product package by their tamper labels. Failure of a scanner to detect all the associated encryptions in all the RFID labels on a given package may result in a tamper warning generated by software executing in the scanning device or an associated computer processor.  
         [0011]     Another exemplary embodiment of the present invention may be viewed as a tamper prevention system that includes two electronic components and their associated destructible conducting paths that are permanently embedded in two separate labels, a “product” label and a “tamper” label. Each electronic component may be an RFID component and may contain an electronic encryption that is associated with the encryption on the other electronic component wherein both encryptions may be read by a scanner. The product label may be attached to a surface of a product or product container such that it would unlikely to be damaged during handling. A tamper label may be attached across each access to the product or may be embedded in the product packaging in such a fashion as to seal each access so that any attempt to tamper with the product would necessarily require the electronic component or antenna embedded in the tamper label or package to be degraded or destroyed.  
         [0012]     When an untampered product is scanned all electronic components transmit their encryptions. The receipt of all of the encryptions by the scanner indicates that the product exists on the shelf and that the tamper labels have not been degraded. When a product with a disabled tamper label is scanned, the receipt of less than all of the encryptions embedded in the product labels may indicate to the scanner that the product exists on the shelf but that a tamper label or product label has been degraded and the product should be removed from offer. When a product with a disabled product label is scanned, the receipt of only the encryption embedded in the tamper label may indicate to the scanner that the product exists on the shelf but that the product label has been degraded and the product should be investigated if not removed from offer.  
         [0013]     An embodiment of the present invention may be viewed as a method to detect product tampering that includes irremovably affixing a product RFID label (“PRFIDL”) to a surface of a product package, wherein the PRFIDL integrally includes a first electronically readable encryption recorded on a first RFID component connected to a first destructible conducting path. Irremovably affixing one or more tamper RFID labels (“TRFIDL”) to one or more accesses in the product package, wherein penetrating any of the one or more accesses shall disrupt an additional destructible conducting path electrically connected to an additional RFID component each of which are integrally attached to the one or more TRFIDLs, wherein further the additional RFID component contains an additional electronically readable encryption that is associated with the first electronically readable encryption. Reading from the PRFIDL and the one or more TRFIDLs the first electronically readable encryption and the additional electronically readable encryption(s). Storing the first electronically readable encryption into a first database and the additional electronically readable encryption(s) into a second database. Comparing the first database with the second database, wherein the existence of the first electronically readable encryption in the first database without finding the associated additional electronically readable encryption in the second database generates an error. And storing the error in a data schema and generating an error report.  
         [0014]     An exemplary embodiment of the present invention may be viewed as a device to detect product tampering that includes a PRFIDL portion and one or more tamper strip portions. At least one RFID component is fixedly attached to each of the PRFIDL portion and at least one of the tamper strip portions. The PRFIDL portion and the one or more tamper strip portions may each be a separate sheet of material or different portions of the same sheet of material. At least one destructible conducting path is electrically attached to each of the RFID components and fixedly attached to the portion of its respective RFID component, wherein the at least one destructible conducting path is routed through the tamper strip portion and another destructible conducting path is routed through the PRFIDL. A means for permanently attaching the at least one sheet to at least one surface, wherein any attempt to manipulate the at least the one surface shall disrupt the at least one destructible electrically conducting path.

     DETAILED DESCRIPTION  
       [0032]     Embodiments of the present invention include tampering prevention labels and associated methods of constructing, attaching and applying the tamper prevention labels to a variety of product packages. Certain embodiments of the present invention include multiple RFID components embedded in multiple labels. Certain embodiments of the present invention include multiple RFID components embedded in different portions of a single label namely a product portion and one or more tamper portions. Certain embodiments of the present invention include RFID components embedded in TRFIDL&#39;s that include tamper strips. Certain embodiments of the present invention include RFID components embedded in a variety of specialty TRFIDL&#39;s such as shrinkwrap which is a non-limiting example of a substrate.  
         [0033]      FIGS. 1   a,    1   b  and  1   c  show various views of an illustrative embodiment of the present invention utilizing multiple RFID components  103  and  104  and their respective destructible conducting paths  102  and  105  on a single sheet  106 . The sheet  106  is theoretically partitioned into a tamper portion or TRFIDL T and a product portion or PRFIDL P. The terms “portion” and “label” may be used interchangeably.  FIGS. 1   a,    1   b  and  1   c  are merely exemplary and non-limiting. The actual size and shape of the sheet  106  as well as whether the portions of sheet  106  are physically divided into separate labels is determined by the physical dimensions of the object or package that the PRFIDL P or TRFIDL T is to be permanently attached and the designer&#39;s preference. The sheet may contain any number of RFID components and be divided into a similar number of portions as required by the desired end use.  
         [0034]      FIG. 1   a  is an illustrative embodiment wherein a sheet  106  contains two RFID components  103  and  104  and their associated destructible conducting paths  102  and  105 . This example demonstrates an embodiment utilizing only two RFID components for clarity, a single tamper RFID component  103  and a product RFID component  104 . Each RFID component  103  and  104  is electrically attached to its own destructible conducting path  102  and  105 . It is well known in the art that a destructible conducting path may be constructed from a number of materials. A non-limiting list of examples may include metallic ink, metallic glue, deposited metal, dielectric material, etc. and may be manifested as a simple conducting path, an induction loop or a variety of resistive, inductive and capacitive circuits (not shown). An RFID component may be any number of RFID chips currently on the market or that will be in the future as would be known to one skilled in the art. As a non-limiting set of examples, such chips may be transponders, memory chips, EPROMs, PROMs or MU chips. The product RFID component  104  contains a unique encryption that is associated with an encryption on the tamper RFID component  103 . The utilization of the encryptions will be further discussed in a later section, infra. Each RFID component  103  and  104  is irremovably affixed to its portion of the sheet, T and P respectively, by means as is commonly known in the art. In turn, each of the TRFIDL T and the PRFIDL P are irremovably adhered to a product or product container.  
         [0035]     As long as each RFID component  103  and  104  and its respective destructible conductive path  102  and  105  remains intact, exposure to radio frequency energy will cause each of the RFID components  103  and  104  to transmit its encryption that can be received and processed by at least one RFID scanner (not shown). There are a number of RFID scanners on the market that may be adapted for use with the present invention. The receipt of both associated encryptions will indicate that the product exists on the shelf and that it&#39;s TRFIDL T has not been tampered with. Should the tamper RFID component  103  or its destructible conducting path  102  be disabled, only the encryption received may be from the product RFID component  104 . Such a condition would indicate that a product exists on the shelf with a broken TRFIDL T and needs to be removed as being potentially compromised. Should the product RFID component  104  or its destructible conducting path  105  be disabled, the only encryption received may be from the tamper RFID component  104 . Such a condition would indicate that a product exists on the shelf with a broken or missing product label P and needs to be removed as being potentially compromised.  
         [0036]      FIG. 1   b  is an exemplary mechanical view of the sheet  106  indicating that the product label portion P may have a product label adhesive  109  applied to one side of the product label portion P. The product label adhesive  109  fixedly attaches the product label portion P to the surface of a product package (not shown). The tamper label portion T may have product label adhesive  109  applied to a section of the tamper label or a different label adhesive as determined by the user for a given use. It is preferable that an irremovable tamper label adhesive  107  be applied to at least a section of the tamper strip portion(s)  101  whereby the tamper strip portion(s)  101  is irremovably adhered to the surface of the product package to which it is attached so that there is no ability to manipulate the surface without tearing or otherwise disrupting the tamper strip portion  101 . Tearing the tamper strip portion  101  breaks the destructible conducting path embedded therein  102  and renders it an open circuit. The disruption of the destructible conducting path  102  is preferably facilitated by a perforation  108  or other mechanism weakening the juncture of the tamper strip(s)  101  to the main section of tamper portion T.  FIG. 1   c  illustrates the non-adhesive side of the sheet  106  whereon the user may apply his product logo  112 , information, bar codes  110  and any warnings that may be desired  111 . The sheet is wrapped about and adhered to the circumference of the product package with the tamper portion T of the package closest to an access of the product package such that the tamper strip(s)  101  extend beyond the access of the package to be sealed. Each of the tamper strips  101  are then folded down across the package access such that the tamper adhesive  107  irremovably attaches to the surface of the product access (i.e. a box flap or a pill bottle cap) or to each other such that the access may not be manipulated without destroying the tamper strips  101  and the destructible conducting path  102  embedded therein.  
         [0037]      FIG. 2   a  is another non-limiting, illustrative embodiment of another TRFIDL T. The TRFIDL T and its companion PRFIDL P (not shown) are separate although necessarily used together. The TRFIDL T and PRFIDL P with their embedded RFID components and destructible conducting paths are adhered to a product package separately. An RFID component  203  and its associated destructible conducting path  202  are embedded in the TRFIDL T. In this embodiment, TRFIDL T, may include four tamper strips  201  and the destructible conducting path  202  may be routed through all four tamper strips  201 .  
         [0038]     The TRFIDL T is coated with a tamper adhesive  207  at the distal end of each tamper strip  201  and in the center of the TRFIDL T. The TRFIDL T and the location of the tamper adhesive  207  may be of any size and shape and is tailored by the user in order to fit the subject product package.  FIG. 2   b  illustrates an exemplary application of this non-limiting exemplary embodiment to a bottle. The bottle could be a pill bottle as used in a nursing home. The center of the TRFIDL is irremoveably and adhesively attached to the surface of the product package access  209  (i.e. the bottle top) by the tamper adhesive  207  and the distal ends of the tamper strips  201  are irremoveably and adhesively secured to the surface of the product package (i.e. the bottle)  210  by their tamper adhesive  207 . With the TRFIDL T placed as shown in this embodiment, the bottle top  209  can not be removed or the product accessed through the bottle top without tearing or puncturing part of the TRFIDL T thus destroying the RFID component  203  or the destructible conducting path  202 . The actual placement of the tamper RFID component and the routing of the destructible conducting path may be anywhere on the TRFIDL T and is determined by the user in such a way to ensure that the tamper RFID component or destructible conducting path is rendered inoperable when the product package is inappropriately manipulated. The tearing of the TRFIDL T and the destruction of the destructible conducting path  202  may be facilitated by incorporating a perforation  208  or otherwise weakening the junction of a temper strip to the remainder of the temper portion T.  
         [0039]      FIG. 3   a  is another preferred embodiment of a TRFIDL T. The TRFIDL T and its companion product portion P (not shown) with their embedded RFID components and destructible conducting paths are separate although necessarily used together. The illustrated embodiment may be used to tamper seal a box end such as is commonly know and in widespread usage. In this non-limiting example, TRFIDL T has one tamper RFID component  303 . The tamper RFID component is electrically attached to a destructible conducting path  302  which is routed throughout the TRFIDL T.  FIG. 3   b  depicts the TRFIDL T as it is applied to a package or box end. The drawing is of a non-limiting example. The actual size and shape of the TRFIDL T, the number and proportions of the TRFIDL(s) T and the routing of the destructible conducting path is determined by the user in order to accommodate the dimensions of the package to be sealed. As with the other embodiments, one side of the TRFIDL T is coated with an adhesive (not shown) such that it becomes irremovably attached to the box when placed across the box end  313  such that any manipulation or puncture of the TRFIDL T will cause the destruction of the tamper RFID component  303  or the destructible conducting path  302 . The destruction of the conducting path  302 . The destruction of the destructible conducting path  302  is facilitated by the use of a perforation  308  or other means of weakening the TRFIDL T at a predesignated location.  
         [0040]      FIG. 3   c  depicts an exemplary TRFIDL T as it is applied to a blister pack that may commonly be used for packaging medicines. The drawing is of a non-limiting example. The actual size and shape of the TRFIDL T, the routing of the destructible conducting path is determined by the user in order to accommodate the dimensions of the package to be sealed and the layout of the product being contained. As with the other embodiments, one side of the TRFIDL T is coated with an adhesive (not shown) such that it becomes irremovably attached to the package when placed across the perforated press out areas  308  such that any removal or puncture of the TRFIDL T will cause the destruction of the tamper RFID component  303  or the destructible conducting path  302 . The destruction of the destructible conducting path  302  is facilitated by the use of a perforation  308  or other means of weakening the TRFIDL T at a predesignated location(s).  
         [0041]      FIG. 4   a  illustrates another preferred embodiment of the invention. As in all the other embodiments, the TRFIDL T is necessarily used in conjunction with a product portion P (not shown). This preferred embodiment may be applied to seal a container opening. As a non-limiting example, such a container may be a bottle such as ketchup bottle or a bottle of motor oil  413 . The opening may be of any shape. The TRFIDL T may be used under and in addition to a bottle cap or a twist top. In this exemplary embodiment, the entire TRFIDL T with the exception of the immediate area containing the tamper RFID component  403  may be a tamper strip  406 . The TRFIDL T contains a tamper RFID component  403  and a destructible conducting path  402 . The shape and routing of the destructible conducting path may be of any configuration as desired by the user to conform to the dimensions of the product package and the product.  FIG. 4   b  illustrates the TRFIDL T when fixed to an opening. The TRFIDL T may be irremovably attached to the opening to be sealed by a tamper adhesive (not shown) as is known in the art of packaging or it may also be irremovably attached by crimping or other means as is well known in the art of product packaging.  
         [0042]      FIGS. 5   a,    5   b  and  5   c  illustrate yet another preferred embodiment of the invention. As in all the other embodiments, the TRFIDL T is necessarily used in conjunction with a product portion P (not shown). This preferred embodiment may be applied to seal the flaps of a box end. As a non-limiting example, such a container may be a small box such as pharmaceutical box  513 . The opening may be of any shape. The TRFIDL T may be used between an inner flap  514  and an outer flap  517 . The TRFIDL T contains a tamper RFID component  503  and a destructible conducting path  502 . In this embodiment the entire TRFIDL T with the exception of the immediate area containing the tamper RFID component  503  may be a tamper strip. The shape and routing of the destructible conducting path may be of any configuration as desired by the user to conform to the dimensions of the product package and the product.  FIG. 5   b  illustrates the TRFIDL T when fixed to an opening. The TRFIDL T may be irremovably adhered to the top side of the inner flap  514  by a tamper adhesive  507 , when closed, and it may also be irremovably adhered to the underside of the outer flap  517 , when closed, by an adhesive tear off layer  515 . The TRFID label T is thus irremovably sandwiched between the inner and outer flap and will be disabled when the box end is opened and adhesive tear off layer  515  tears the destructible conducting path  502 . The tearing of the destructible conducting path  502  may be assisted by designing the TRFIDL T with pre-weakened areas as is known in the art.  
         [0043]      FIGS. 6   a  and  6   b  illustrate yet another preferred embodiment of the invention. As in all the other embodiments, the TRFIDL T is necessarily used in conjunction with a PRFIDL P (not shown). This exemplary embodiment may be applied to seal a twist off cap to a bottle  601 . As a non-limiting example, such a container may be a soda pop bottle. The TRFIDL T may be comprised of a plastic substrate such as shrinkwrap which is situated around the neck and cap of the bottle. The tamper RFID chip  603  is embedded on the inside of the substrate  606  is electrically connected to a destructible conducting path  602  which winds around the inside of the substrate  606  as shown. The tamper RFID chip may be located anywhere along the route of the destructible conducting path. As the bottle cap  601  is manipulated for removal, the substrate  606  may tear, destroying the destructible conducting path and thereby preventing the tamper RFID chip from transmitting. The nature of the substrate is not critical to the present invention and any material may be used as determined by one skilled in the art to fit the bottle and accept the embedding of tamper RFID chip  603  and its destructible conducting path  602 . To facilitate the destruction of the RFID components, it is preferred that the substrate  606  include one or more perforations  608  and that the substrate be adhered to the cap  601  and the bottle  610 .  
         [0044]     As previously discussed, supra, the preferred embodiments of the present invention each utilize a PRFIDL  701  plus one or more TRFIDLs  702  as illustrated in  FIG. 7 . The PRFIDL  701  acts in the role of product identification and the TRFIDLs  702  seal the accesses in a product&#39;s packaging to prevent or identify tampering. In operation, a plurality of product packages are scanned simultaneously by radiating radio frequency energy at them using a RFID reader  703 . Such readers may be hand held and scan a single package at a time and others may be capable of scanning entire pallets, shelves or rooms of product. One may use multiple readers if desired and may use scanners with multiple antennas. Off the shelf RFID scanner/readers may be adapted for use by the present invention, the techniques for which are well known in the industry. It must be noted that although most of the RFID technology discussed herein concerns passive RFID components that do not require an internal energy source, RFID components utilizing a battery or other internal power source may also be integrated into the present invention utilizing the same principals disclosed herein. It should be further noted that to the extent that an RFID component and a destructible conducting path are compatible with a particular packaging material and manufacturing process, the RFID component and the destructible conducting path may be embedded directly into the packaging material itself.  
         [0045]     As discussed above, each PRFIDL  701  and TRFIDL(s)  702  attached to a given product package  700  contains an embedded RFID component upon which an unique encryption may be recorded that may read by a RFID reader  703  as long as the RFID component, including any corresponding destructible conducting path, is physically intact and operable. Each encryption on a particular product should preferably be truly unique relative to the product stock in the user&#39;s supply chain. However, it is entirely conceivable that the encryptions could be reused after an elapsed time wherein the user is certain that the previous product package utilizing the encryption no longer exists in the supply chain. The creation of the encryptions is completely at the discretion of the system user.  
         [0046]     Although the encryptions on the PRFIDL  701  and each TRFIDL  702  may be unique from each other and from the rest of the encryptions on product packages in the area, they should preferably be logically associated with each other. As a non-limiting example, employing a PRFIDL  701  and a single TRFIDL  702  for clarity of demonstration, the PRFIDL  701  may have a recorded encryption that comprises the product&#39;s Uniform Product Code (UPC), a serial number (S/N) such as:  
                                                       Encryption   UPC   S/N                           8522762903 345 =   8522762903 +   345                      
 
 In this example, the number 8522762903 is the UPC and 345 is the serial number. 
 
         [0047]     The encryption on the package&#39;s corresponding TRFIDL  702  may be associated by reusing the UPC and serial number and then adding a third number which is a tamper label code such as 2302. The resulting TRFIDL  702  encryption may then be:  
                                               Encryption   UPC   S/N   Tamper code   TPL#                   8522762903 345 2302 1 =   8522762903   345   2302   1                  
 
         [0048]     It should be noted that the encryptions may be any combination of letters, numbers or symbols that may be read by the RFID reader  703  and interpreted by the RFID reader&#39;s software executing on a computer  704 . In the case where there are multiple TRFIDLs attached to a single product package, their encryptions could all be made unique and associated by assigning additional Tamper codes such as 2303, 2304 . . . for instance. Adding a specific identification of each of the multiple TRFIDL applied to a package may also be included (i.e. TPL#). Another possible example of creating unique encryptions is to add code for the date and time of the TRFID label&#39;s printing. As one of ordinary skill in the art would recognize, The combinations and permutations available to produce unique and associated encryptions are multitudinous and at the discretion and taste of the system designer.  
         [0049]     In use, the RFID Scanner/Reader(s)  703  radiates throughout an area containing a multitude of products and product packages. Each RFID component embedded on each PRFIDL and TRFIDL in the radiated area in turn is energized to broadcast its encryption. If a PRFIDL or a TRFIDL has been tampered with or otherwise damaged such that the embedded RFID component or its associated destructible conducting path is no longer operable, that unique encryption will not be broadcast with its associated encryptions from the other label(s). The RFID Reader  703  will pickup all of the transmitted encryptions for the various product packages which will, in turn, be processed by the RFID software executing on the RFID Reader&#39;s computer  704 . The use of multiple scanner readers may reduce reception errors and allow for location by triangulation or by zone tracking as the product moves from place to place within a facility.  
         [0050]      FIG. 8  presents a non-limiting, exemplary logic flow of the RFID Scanner/Reader software executing on computer  704 , the software being stored on a computer readable medium to be executed on a computer processor. It would be obvious to one skilled in the art that variations to the exemplary logic diagram could be made without parting from the scope and spirit of the invention and are contemplated herein. In this exemplary flow diagram, the process begins at steps  800  where the RFID Reader  703  queries the product  700 . The transmitted encryption from the TRFIDL  702  (the “TPL Code”) is read into computer  704  at step  804 . Since the TRFIDL(s)  702  and PRFIDL  701  are queried simultaneously, the order in which they are processed is not of consequence. In step  808 , the TPL is checked for validity or corruption. If the received TPL is corrupted, it is logged and an error message or an alert is returned. That alert may be in the form of a prerecorded announcement file to one or more central offices of a communications network. If the TPL is valid, it is parsed for further processing in step  812 . The same procedure is repeated for the encryption received from the PRFIDL  701  (the “PL Code”) whereby the PL Code is read into the computer  704  at step  814  and checked for error in step  816 . Invalid PL Codes and TPL Codes are logged and an error message is returned in steps  822  and  810 , respectively. The PL Code is parsed for further processing in step  818 .  
         [0051]     It should be reiterated that in practice a plurality of items may be scanned at one time. As such a plurality of TPL Codes and PL Codes will be received essentiually simultaneously. As such, a data array, database or other data schema may be employed to store the TPL Codes and the PL Codes prior to being scanned for error and processed further. For example the TPL Codes could be stored in a first data base and the PL Codes in a second database and the two databases then compared. Any number of parallel or mass data processing techniques known in the art of data processing may be used. An exclusive teaching of serial processing of the TPL and PL Codes should not implied by way of this exemplary flow diagram. As another non-limiting example, processing may be done in parallel and different databases could be compared against each other.  
         [0052]     In step  820 , the received TPL and PL codes are compared among themselves for matching encryptions or for matching segments of the encryption which will indicate that one or more TPLs and the PL are from the same product item  700 . The comparison process my comprise a simple looping algorithm or may comprise a more sophisticated logic process as would occur to one skilled in the art. In the present non-limiting example, the parsed encryptions are checked for error in step  824 . It would be desirable to confirm that the parsing and comparison processes in steps  812 ,  818  and  820  did not result in creating errors to the parsed TPL and PL codes prior to further processing. The use of error check points is a routine step in most computer programs and may be conducted at any point in the process as desired by the user. Any errors found in step  824  are recorded to an error database and an alert is generated  826 . An alert generated in step  824  may be indicative of a missing TPL Code and PL Code caused by a missing or a tampered TRFIDL T or a PRFIDL P that my require that the associated product item  700  be removed from offer.  
         [0053]     In step  828  a data base resident and executing as a part of RFID Scanner/Reader software executing on computer  704 , is consulted to determine how many TRFIDLs T are expected to be attached to each product item  700 . If multiple TRFIDLs T are expected  830  on each product item  700 , then the plurality of received TPL Codes is searched until a related TPC Code for that particular item  700  is identified in step  832 . When a TPL Code corresponding to the product item  700  has been identified or if only one TPL Code is expected, the TPL Codes are inventoried  834  by looking for a characteristic TPL# within the encryption that identifies each individual TRFIDL T. As indicated above, the TPL# may be as simple as a sequential integer assigned to each TRFIDL T attached to the product item  700  and appended to the TRFIDLs T encryption. If multiple TPL Codes are expected and the computer  704  does not have the expected TPL#  836  with which to inventory the TRFIDLs T, an error is generated and reported in step  840 . In step  838  the TPL# is read and inventoried against the expected number in the data base resident and executing as a part of RFID Scanner/Reader software executing on computer  704 . If less than all of the expected TRFIDLs are accounted in step  838 , an error is generated in step  842  and an alarm is generated  846 . An alarm generated at step  846  is not indicative of a data processing or a data read error. An alarm at this point is indicative of a missing or non-functioning TRFIDL T and may be the result of tampering or a manufacturing error requiring that the associated product item  700  be removed from offer. At step  844 , process for a given product item  700  is terminated when all of the TPL codes and the PL codes have been identified and inventoried.  
         [0054]     What has been described is merely illustrative of the present invention in a variety of exemplary embodiments. Other applications of a TRFIDL T and a PRFIDL P as well as other component logic subroutines are contemplated as being within the knowledge of one skilled in the art and may be utilized without departing from the spirit and scope of the present invention.
