Title: Cards with non-visible production indicia and related systems

Description:
RELATED APPLICATIONS 
     This application claims the priority benefit of U.S. Provisional Patent Application No. 62/578,152 filed Oct. 27, 2017, entitled “CARDS WITH NON-VISIBLE PRODUCTION INDICIA AND RELATED SYSTEMS”, which application is incorporated herein by reference in its entirety. 
    
    
     BACKGROUND OF THE INVENTION 
     Data bearing cards are employed in a wide variety of applications, including transaction cards (e.g. credit cards, debit cards, store-value cards and loyalty/membership cards), identification cards (e.g. cards for verifying the identity of a card holder), and access cards (e.g. cards provided for use in accessing controlled premises). Such data bearing cards typically include personalization data unique to each given card (e.g. data uniquely associated with a specific payment account and/or authorized card holder and/or other stored record). 
     As may be appreciated, data bearing cards are typically produced and personalized in large quantities by a given card manufacturer to fulfill a given card order. In some instances, a number of data bearing cards produced for a given order may include a number of data bearing cards that are either defective or within a determinable range of being defective. However, upon inspection of the defective or near-defective data bearing cards, a card manufacturer may not be able to accurately determine a specific production-related source of the defects or near-defects, thereby making it difficult for the card manufacturer to take effective and efficient remedial action, including for example, replacement of defective data bearing cards and/or correction of the production-related source of such defects or near-defects. 
     SUMMARY OF THE INVENTION 
     The present disclosure encompasses data bearing cards and related production systems and methodologies that employ non-visible production indicia on the cards that facilitates improved remedial action by a card manufacturer in response to a determination that one or more defects or near-defects are present in one or more data bearing cards or card bodies produced by the card manufacturer and/or that otherwise facilitates the tracking of data bearing cards or card bodies thereof during production by the card manufacturer. 
     In one embodiment, a data bearing card is provided that includes a card body, personalization data unique to the data bearing card, and non-visible production indicia, disposed on the card body and indicative of production-related information not otherwise provided on the data bearing card. In the later regard, the non-visible production indicia may be separate from and/or otherwise non-indicative of the personalization data. 
     The non-visible production indicia may be of a type that becomes visible or otherwise detectable when viewed with use of a complimentary type of detection device, as will be further addressed. In turn, upon detection of the production indicia the production-related information may be determined. As may be appreciated, production-related information may be employed to facilitate remedial action in the event that a defect or near-defect is found in the card body or other components of the data bearing card and/or to otherwise facilitate tracking of data bearing cards or card bodies thereof during production of the data bearing cards. 
     In some embodiments, the non-visible production indicia may be indicative of at least one of the following:
         a location of a corresponding one of a predetermined plurality of regions of a sheet assembly from which the corresponding card body is separated during production as one of a plurality of separated card bodies (e.g. a location of a region within a given row and/or column of regions comprising the plurality of regions of the sheet assembly);   a corresponding piece of equipment utilized in connection with the production of the corresponding data bearing card or card body;   at least one of a corresponding type of and corresponding source of material utilized to produce the corresponding card body;   at least one corresponding operator of at least one corresponding piece of equipment utilized in connection with the production of the corresponding data bearing card or card body;   a corresponding process utilized in connection with the production of the corresponding data bearing card or card body (e.g. including automated and/or manual processes); and,   a corresponding production batch produced to fulfill a corresponding order for a plurality of data bearing cards that includes the corresponding data bearing card.
 
By way of example, the ability to determine a sheet assembly location from which a given defective card body was separated during production of a corresponding plurality of data bearing cards may allow the card manufacturer to take improved remedial action in relation to selective replacement of defective data bearing cards having associated sheet assembly locations and/or in relation to the repair/replacement of production equipment utilized in relation to the given sheet assembly location.
       

     In some implementations, the non-visible production indicia may be of a type that is non-visible to the human eye when illuminated with electro-magnetic radiation within the wavelength range of about 390 mm to 700 mm. In particular, the non-visible production indicia may comprise a non-visible ink marking that is printed within a predetermined location on the card body. In some implementations, the non-visible production indicia is a non-visible ink that comprises at least one of the following:
         an ultra-violet light sensitive ink;   an infrared light sensitive ink; and,   a polarized light sensitive ink.       

     In turn, upon viewing the otherwise non-visible ink marking with use of a complimentary detective device comprising a complimentary electro-magnetic radiation source (e.g. an ultra-violet, infrared or polarized light source), the production indicia may be detected (e.g. via human and/or automated detection) and the corresponding production-related information may be determined (e.g. via human and/or automated determination). 
     Additionally or alternatively, in some embodiments, the non-visible production indicia may comprise at least one non-visible particle having a size that is not visible to the human eye. For example, the non-visible production indicia may comprise one or more particles provided on the card body and having a maximum cross-dimension that is less than about 0.1 mm. In turn, upon viewing the otherwise non-visible particles with use of a complimentary detection device comprising a complimentary magnification device, the production indicia may be detected and the production-related information may be determined. 
     In some implementations, the non-visible production indicia may comprise one or more micro-particle taggants. By way of example, such taggants may comprise one or a plurality of colored layer(s) that have a predetermined meaning associated therewith, one or a plurality of layer(s) having a coloration that is ultra-violet light sensitive (e.g. not visible unless viewed under predetermined ultra-violet light) and/or infrared light sensitive (e.g. not visible unless viewed under a predetermined infrared light), and/or one or a plurality of marking(s) disposed thereupon (e.g. a marking that includes human readable characters and/or that is otherwise machine-readable). 
     In some embodiments, a plurality of non-visible particles each bearing the same non-visible production indicia may be dispersed across and/or within the card body in an amount sufficient to insure detectability of at least one of the particles (e.g. within a predetermined location) on the card body with use of a complimentary detection device. In one approach, the particles may be dispersed within an ink that is printed on the card during production (e.g. an otherwise visible ink utilized for printed graphics and/or human-readable characters). In another approach, the particles may be dispersed within a material defining or coating applied across one or more layers of the card body. In either case, the particles may each bear non-visible production indicia indicative of at least one of a corresponding type of and corresponding source of material utilized to produce the corresponding card body. 
     In some implementations, the card body may include a first core layer, wherein the predetermined location of the non-visible production indicia is provided on the first core layer. The card body may further include a transparent first outer layer disposed on a first side of the first core layer in overlying relation to the non-visible production indicia. 
     In conjunction with such embodiments, the data bearing card may further include visible printing on the first core layer. In such implementations, the visible printing and non-visible production indicia may each be disposed within a common region of the first core layer (e.g. a region within which visible graphics, visible human-readable characters and/or a visible machine-readable marking(s) are printed). In that regard, the visible printing and non-visible production indicia may each be printed on the first core layer in a continuous printing operation. 
     In another embodiment, a sheet assembly for providing a plurality of card bodies for a plurality of data bearing cards is provided. The sheet assembly may include at least a first layer (e.g. a continuous layer of material), and non-visible production indicia disposed within each of a predetermined plurality of regions of the sheet assembly on the first layer thereof, wherein each of the predetermined plurality of regions corresponds with a different one of the plurality of card bodies. In turn, for each of the predetermined plurality of regions, the non-visible indicia may be indicative of production-related information. 
     In contemplated embodiments, for each given region of the plurality of predetermined plurality of regions of the sheet assembly, the non-visible production indicia may be indicative of at least one of the following:
         a corresponding location of the given region on said sheet-assembly;   a corresponding piece or portion of equipment utilized in connection with the production of the corresponding card body;   at least one of a corresponding type and a corresponding source of material comprising the sheet assembly;   a corresponding process utilized in connection with the production of the corresponding card body;   at least one corresponding operator of at least one corresponding piece of equipment utilized in connection with the production of the corresponding card body; and,   a corresponding production batch produced to fulfill a corresponding order for a plurality of data bearing cards.
 
For example, the predetermined plurality of regions may be arranged in a predetermined plurality of rows and columns. In turn, for each given region of the predetermined plurality of regions, the non-visible production indicia may be indicative of at least one or both of the corresponding row and corresponding column of the given region.
       

     In some implementations, for each of the predetermined plurality of regions of the sheet assembly the corresponding non-visible production indicia may comprise at least one of the following:
         a non-visible ink printed on the first layer; and,   a non-visible particle supported by the first layer.
 
In turn, the sheet assembly may further include a transparent second layer interconnected to the first layer and overlying the non-visible production indicia located within each of the plurality of regions. As may be appreciated, the utilization of a transparent second layer facilitates protection of the first layer and non-visible production indicia provided thereupon, while also accommodating later detection of the non-visible production indicia on one or more of the data bearing card bodies of the corresponding plurality of data bearing cards with use of a complimentary detection device.
       

     In additional embodiments, a method may be provided for use in connection with the production of a plurality of data bearing cards that each include a corresponding card body, corresponding personalization data unique to the data bearing card, and corresponding non-visible production indicia indicative of production-related information not otherwise provided on the data bearing card, comprising the step of providing non-visible production indicia in each of a predetermined plurality of regions on at least one of a top side and a bottom side of a first layer of a sheet assembly, said non-visible production indicia being indicative of product-related information. Further, the method may include separating a plurality of card bodies from the sheet assembly in corresponding relation to the predetermined plurality of regions of the sheet assembly, and supplying personalization data to each of the plurality of card bodies to define the plurality of data bearing cards, after the providing and separating steps. For example, the predetermined plurality of regions may be arranged in a predetermined plurality of rows and columns. In turn, for each given region of the predetermined plurality of regions, the non-visible production indicia may be indicative of at least one or both of the corresponding row and corresponding column of the given region. 
     In some implementations, for each of the predetermined plurality of regions the corresponding non-visible production indicia may comprise at least one of the following:
         a non-visible ink printed on the first layer; and,   a non-visible particle supported by the first layer.
 
In turn, the method may further include the step of interconnecting a transparent first outer layer sheet to said at least one of a top side and a bottom side of the first layer, prior to the separating and supplying steps.
       

     In some embodiments, the providing step may include printing the non-visible production indicia in each of the plurality of regions on said at least one of a top side and a bottom side of the first layer. Further, such printing may further comprise printing of at least one of the following in each of the plurality of regions on said at least one of a top side and a bottom side of the first layer:
         visible graphics;   visible human-readable characters; and,   a visible machine-readable marking.
 
In turn, the method may further include interconnecting a transparent first outer layer sheet to the at least one of a top side and a bottom side of the first layer, prior to separating and supplying steps.
       

     In some implementations, the method may further include using a detection device to view the non-visible production indicia on at least one of the plurality of card bodies or data bearing cards, wherein the corresponding production-related information may be determined and employed to facilitate remedial action in response to an identified defect or near-defect and/or to otherwise facilitate tracking during production. In later regard, the method may include using a first detection device to view the non-visible production indicia in at least one of the plurality of regions in relation to at least one or both of the printing step and the interconnecting step, wherein the corresponding production-related information is employable to track a location of the sheet assembly during production. As may be appreciated, the first detection device or one or more additional detection device(s) may be provided for use in viewing the non-visible production indicia in one or more of the plurality of regions in relation to one or more additional production steps utilized during production of the plurality of card bodies, wherein the corresponding production-related information may be employed to track the location of the plurality of data bearing cards or card bodies. In turn, location information and corresponding time information may be stored and utilized to provide production status information, scheduling information and/or to assess and address production resource requirements. 
     In further embodiments, a system may be provided for use in connection with the production of a plurality of data bearing cards that each include a corresponding card body, corresponding personalization data unique to the data bearing card, and corresponding non-visible production indicia indicative of product-related information not otherwise provided on the data bearing card. In such embodiments, the system may include card production equipment for use in connection with the production of the plurality of data bearing cards, and a card production processer for maintaining stored information in a database pertaining to utilization of the card production equipment in connection with the production of the plurality of data bearing cards. Further, the system may include at least one detection device for use in viewing at least one of the plurality of data bearing cards or plurality of card bodies to allow detection of the corresponding non-visible production indicia and a determination of the corresponding production-related information, wherein said card production processor is operable to employ the corresponding production-related information and the stored information to facilitate one or both of:

In some embodiments, visible personalization indicia  40   a  and/or  40   b  may be provided by embossing card body  2  to define the indicia. In other embodiments, visible personalization indicia  40   a  and/or  40   b  may be defined by printing on one or more layers of the card body  2 . In still other embodiments, visible personalization indicia  40   a  and/or  40   b  may be defined in outward-facing surface of the first outer layer  20  (e.g. by at least one of laser engraving, ink jet printing and thermoprinting). Visible personalization data  40   a ,  40   b  may be provided in predetermined regions  60   c , wherein one or more predetermined location  50   b  comprising non-visible production indicia may be disposed within one or more of such predetermined regions  60   c.    
     The visible personalization indicia  40   a  may comprise human-readable characters indicative of a corresponding account (e.g. account number). Further, visible personalization indicia  40   b  may include additional human-readable data corresponding with a given account, including a corresponding card expiration date, a corresponding account service grade level, and/or corresponding customer-specific data (e.g. customer name, customer duration, data, etc.). In the transaction card  1  embodiment of  FIGS. 1A and 1B , visible indicia  40   a ,  40   b  are provided for viewing from a first side of the transaction card  1 . In other embodiments, visible indicia  40   a  and/or  40   b  may be also or alternately provided for viewing from the second side of the transaction card  1 . As may be appreciated, the visible indicia  40   a ,  40   b  may be provided as personalization data on transaction card  1  as a part of card personalization processing. 
     As referenced above, transaction card  1  includes at least one predetermined location  50   a ,  50   b  or  50   c  on card body  2  comprising non-visible production indicia indicative of production-related information not otherwise provided on the transaction card  1 . In that regard, the non-visible production indicia may be provided to be invisible to the human eye, but visible when viewed utilizing a complimentary detection device. In particular, upon a determination that a given card body  2  or transaction card  1  may include a production-related defect or near-defect (e.g. a product feature within a determinable range of being a production defect), the corresponding predetermined location  50   a ,  50   b  or  50   c  may be viewed utilizing a complimentary detection device to detect the corresponding production indicia and thereby determine the production-related information. In turn, the production-related information may be utilized by the corresponding card manufacturer to take efficient and effective remedial action. 
     In that regard, for a given transaction card  1  or card body  2 , the corresponding non-visible production indicia may be indicative of one or more of the following types of production-related information:
         a location of a corresponding one of a predetermined plurality of regions of a sheet assembly from which the corresponding card body  2  was separated during production as one of a plurality of separated card bodies (e.g. a location of a region within a given row and/or column of regions);   a corresponding piece of equipment utilized in connection with the production of the corresponding transaction card  1  or card body  2 ;   at least one of a corresponding type of and corresponding source of material utilized to produce the corresponding card body  2 ;   at least one corresponding operator of at least one corresponding piece of equipment utilized in connection with the production of the corresponding transaction card  1  or card body  2 ;   a corresponding process utilized in connection with the production of the corresponding transaction card  1  or card body  2 ; and,   a corresponding production batch produced to fulfill a corresponding order for a plurality of transaction cards that includes the corresponding transaction card  1 .
 
In one instance, the ability to detect a non-visible production indicia and thereby determine a sheet assembly location from which a given defective card body  2  was separated during production of a corresponding plurality of transaction cards may allow the corresponding card manufacturer to take improved remedial action.
       

     For example, the card manufacturer may be able to inspect additional ones of the plurality of transaction cards to detect corresponding non-visible production indicia and thereby determine that a specific row and/or column of sheet assembly regions of each sheet assembly utilized to fulfill a given order yielded corresponding defective card bodies  2 , thereby allowing the card manufacturer to selectively replace the corresponding defective transaction cards with non-defective transaction cards (e.g. as opposed to replacing all transaction cards for the entire order). Additionally or alternatively, the card manufacturer may be able to inspect additional ones of the plurality of transaction cards to determine that a specific row and/or column of sheet assembly regions of each sheet assembly utilized to fulfill a given order yielded corresponding defective card bodies  2 , thereby allowing the card manufacturer to identify a specific piece and/or portion of production equipment utilized in connection with the production of the defective card bodies  2 , wherein the card manufacturer may take appropriate remedial action (e.g. repair, re-calibrate or otherwise replace such piece and/or portion of production equipment). 
     Similarly, for a given transaction card  1  or card body  2  determined to be defective or near-defective, the ability to determine non-visible production indicia and thereby determine a corresponding piece of equipment and/or process utilized in connection with the production of the given transaction card  1  or card body  2  may allow the corresponding card manufacturer to take appropriate remedial action (e.g. repair, re-calibrate or otherwise replace such production equipment, and/or to modify or otherwise replace such process). For example, for a given plurality of transaction cards  1  or card bodies  2  that were produced utilizing the same or substantially the same production equipment and that include different portions inspected by different inspection processes (e.g. an automated process and manual process), a card manufacturer may be able to further inspect one or more samples from each of the portions to identify defects or near defects and detect corresponding non-visible indicia indicative of the corresponding inspection process to assess the relative accuracy of the different inspection processes and thereby modify or otherwise replace one or more of such inspection processes. 
     As indicated, the non-visible production indicia may be provided to be invisible to the human eye (e.g. unaided by a complimentary detection device). In one approach, the non-visible production indicia may be of a type that is non-visible to the human eye when illuminated with electro-magnetic radiation within a wavelength range of about 390 mm to 700 mm. For example, the non-visible production indicia may comprise a non-visible ink that is printed in a predetermined location  50   a ,  50   b  or  50   c  on one or more layers of the card body  2 .

In that regard, the non-visible production indicia may comprise one or more micro-particle taggants (e.g. taggants that comprise one or a plurality of colored layers that have a predetermined meaning associated therewith, taggants that comprise one or a plurality of layer(s) having a coloration that is ultra-violet light sensitive (e.g. not visible unless viewed under predetermined ultra-violet light) and/or infrared light sensitive (e.g. not visible unless viewed under a predetermined infrared light) and that have a predetermined meaning associated therewith, and/or taggants that comprise human-readable or machine-readable).
       

     The non-visible production indicia may be provided at any of a plurality of predetermined locations of the card body  2 , including but not limited to the exemplary predetermined locations  50   a ,  50   b  and  50   c  shown in  FIGS. 1A and 1B . For example, predetermined location  50   a  is shown as being within a graphics print region  60   a  of printing  22 , predetermined location  50   b  is shown as being within a region  60   b  corresponding with visible personalization data  40   a , and predetermined location  50   c  is shown as being within a human-readable characters print region  60   c  of printing  32 . 
     Returning now to  FIG. 1A , in some embodiments transaction card  1  may also include a pocket  42  defined in a first side of the transaction card  1 , with a plurality of contact pads  44  and an underlying, electrically-interconnected integrated circuit (IC) chip (not shown) disposed within the pocket  42 , wherein the contact pads  44  are located and exposed for contact with a chip card reader for signal transmissions therebetween to complete a financial transaction (e.g. at an ATM location, a point of sale location, etc.). As may be appreciated, contact pads  44  and interconnected IC chip (change) may be provided for electrical contact interface with contact chip card reader, e.g. in compliance with ISO/IEC Standard 7816. In that regard, the IC chip may be encoded during card personalization so as to store personalization data unique to the transaction card  1 , e.g. encoded with data corresponding with the account indicated by visible indicia  40   a . Additionally, an antenna may be provided in pocket  42  in electrical contact with the IC chip. As may be appreciated, the antenna and IC chip may be provided for contactless RF signal transmissions with a contactless chip card reader device to complete a financial transaction (e.g. at an ATM location, a point of sale location, etc.), in compliance with ISO/IEC Standard 1443. In one approach, contact pads  44  may be supportably interconnected to an outward-facing side of a non-conductive substrate and an IC chip and electrically interconnected antenna may be supportably interconnected to an inward-facing side of the substrate, wherein the contact pads are electrically interconnected to the IC chip through the substrate. In some arrangements, an elite brand mark  41  may also be provided on the first side of transaction card  1 .

In some embodiments, the production indicia may be read by a compatible reader device (e.g. included with detection device  100 ) to determine the corresponding production information, as described herein. In some embodiments, one or more non-visible ink marking  52   a  may be printed in conjunction with printing  22  and/or printing  32  (e.g. as part of a continuous printing process). 
     As further shown in  FIG. 2 , predetermined location  50   b  is illustrated to reflect production indicia in the form of a non-visible particle  52   b . By way of example, the particle  52   b  may be a micro-particle taggant, wherein the detection device  100  may comprise magnification componentry so that one or more colored layers of the micro-particle taggant may be identified and correlated to a predetermined meaning to obtain the corresponding production information. Additionally or alternatively, the detection device  100  may comprise a corresponding source of ultra-violet light or infrared light so that one or more layers of the micro-particle taggant that comprise ultra-violet light sensitive or infrared light sensitive coloration may be identified and correlated to a predetermined meaning to obtain the corresponding production information. Additionally or alternatively, the micro-particle taggant may comprise human-readable characters and/or machine-readable markings from which production-related information may be determined. In some embodiments, a plurality of particles  52   b  with substantially identical production indicia may be dispersed across transaction card  1 . For example, the particles  52   b  may be included in an ink utilized for printing  22  and/or printing  32  or otherwise included in a material utilized to fabricate a layer of transaction card  1  and/or a coating applied thereto. 
     As noted above, data bearing transaction card  1  may be produced as one of a corresponding plurality of data bearing transaction cards (e.g. to realize production efficiencies). In that regard, reference is now made to  FIGS. 3 and 4  which illustrate a multi-sheet assembly  200  having a predetermined plurality of regions  201  (e.g. arranged in three rows and three columns) from which nine card bodies  2  may be separated, wherein each of the regions  201  includes a corresponding predetermined location  50  comprising corresponding non-visible production indicia. In contemplated embodiments, a larger multi-sheet assembly may be utilized to yield a greater number of card bodies  2  (e.g.  56  regions/card bodies  2  arranged in eight rows and seven columns or 28 regions/card bodies  2  arranged in four rows and seven columns). 
     As shown in  FIG. 3 , the multi-sheet assembly  200  may include a first outer layer sheet  220  (e.g. corresponding with first outer layer  20  shown in  FIGS. 1A and 1B ), an interfacing first core layer sheet  210  (e.g. corresponding with first core layer  10  shown in  FIGS. 1A and 1B ), an interfacing intermediate layer sheet  260  (e.g. corresponding with an intermediate layer as described above), a second core layer sheet  270  (e.g. corresponding with a second core layer as described above), and a second outer layer sheet  230  (e.g. corresponding with second outer layer  30  shown in  FIGS. 1A and 1B ), wherein the interfacing sheet layers are arranged in stacked co-relation. Further, while not shown, additional polymer-based adhesive sheet-like layers may be provided between each of the interfacing layers of the multi-sheet assembly  200 . For example, each of the polymer based adhesive sheet-like layers may comprise a thermoplastic and/or thermosetting coating coated on at least one of each interfacing set of surfaces of the various sheet layers comprising multi-sheet assembly  200 . 
     As shown in  FIGS. 3 and 4 , the predetermined locations  50   a  comprising corresponding non-visible production indicia may be provided on the first core sheet  210  at common locations within each of the predetermined plurality of regions  201  of sheet assembly  200 . By way of example,  FIG. 4  illustrates non-visible production indicia in the form of non-visible ink marking  52   a  printed in each of the predetermined locations  50   a , wherein upon illumination by a complimentary detection device (e.g. detection device  100  described above) any given one of the markings becomes visible to indicate the corresponding row and column region of a corresponding one of the predetermined plurality of regions  201  comprising multi-sheet assembly  200 . In turn, and as otherwise described herein, upon separation of a plurality of card bodies  2  in corresponding relation to the predetermined plurality of regions  201  of multi-sheet assembly  200 , the location within the multi-sheet assembly  200  from which any given one of the card bodies  2  has been separated may be determined by detection of the corresponding production indicia in the corresponding predetermined location  50   a  of such card body  2 . In turn, in the event such card body  2  is found to be defective or near defective, production equipment corresponding with the row and/or location and/or column of such sheet assembly location may be focused upon for remedial action. 
     To interconnect the various layers of multi-sheet assembly  200 , the above-referenced polymer-based adhesive layers and/or thermosetting layers may be activated by heating and cooled. In that regard and with reference to  FIG. 5 , heat and pressure may be applied to the multi-sheet assembly  200  via opposing plattens  280  of a lamination device and opposing sides of the multi-sheet assembly  200 . 
     Following interconnection of the various layers of the multi-sheet assembly  200 , a plurality of card bodies  2  may be separated from the multi-sheet assembly  200 , as shown in  FIG. 6 . Further, prior to, in conjunction with, or after such separation, pockets  42  may be defined in predetermined relation to each of the card bodies  2  separated or to be separated from the multi-sheet assembly  200 . After separation of the card bodies  2 , the card bodies  2  may be separately processed to incorporate additional components as described above in relation to  FIGS. 1A and 1B , and for prepersonalization encoding and personalization encoding/visible indicia defining purposes. 
     Reference is now made to  FIG. 7  which illustrates one embodiment of a system  300  for use in the production of data bearing cards as described herein. The system  300  may include at least one piece of card production equipment  310  and a card production processor  320  for maintaining stored information pertaining to utilization of the card production equipment  310  in connection with the production of a plurality of data bearing cards (e.g. data bearing cards produced to fulfill a given order). Optionally, the card production processor  320  may be operatively interconnected with the card production equipment  310  to provide an output to and/or receive an input from the card production equipment  310  that comprises the stored information. Further, the card production processor  320  and production equipment  310  may each comprise a user interface (U/I) for the input (e.g. via a keyboard, touchscreen, etc.) and output (e.g. via a display, printer, etc.) of stored information. 
     Additionally, the system  300  may include at least one non-visible production indicia detection device(s)  100  or use in viewing at least one of the plurality of data bearing cards or corresponding plurality of card bodies to allow detection of the corresponding non-visible production indicia and a determination of the corresponding production-related information (e.g. human and/or automated detection and determination). In turn, the card production processor  320  may be operable to employ the corresponding production-related information and stored information to facilitate at least one of:
         remedial action in response to the identification of defect or near-defect in the at least one of said plurality of data bearing cards or plurality of card bodies; and/or,   tracking of the at least one of said plurality of data bearing cards or corresponding plurality of card bodies during production, wherein corresponding tracking information may be included with the stored information.
