Description:
BACKGROUND 
       [0001]    Cards are used for different types of financial transactions, rewards, discounts, gifts, identification, insurance, security, and other like uses. Different types of cards may include credit cards, debit cards (e.g., automated teller machine cards), rewards cards, gift cards, identification cards (e.g., licenses, student identification cards, card badges, and the like), insurance cards (e.g., health insurance, dental insurance, and the like), security cards for entry into secure locations, and other like cards. 
       BRIEF SUMMARY 
       [0002]    The embodiments provided herein are directed to methods and systems used to manufacture cards that comprise indicators on the edge of the card stock to help identify the cards. The tools (e.g., dies) used to create the card stock comprise tool projections formed as ridges, grooves, dimples, burrs, protrusions, or other like projections. The tool projections may extend from or into the edge of the tool. The projections on the dies are used to stamp out card stock having the desired indicators. The indicators on the card stock may be card projections on the edge of the card stock in the form of ridges, grooves, dimples, burrs, protrusions, or other like projections that provide at least a portion of the edge of the card stock with a textured surface. As such, the indicators may allow a person presenting the card or another person accepting the card (hereinafter “user(s)”) to identify the card apart from other cards, for example either by sight or by touch. The card also has a first face (e.g., front face or back face) and a second face (e.g., back face or front face) (hereinafter “faces”). In some embodiments of the invention the card has a first side, a second side, a third side, and a fourth side, comprising a surface of the card extending around the sides of the card that forms an edge around the card. In other embodiments of the invention the card may have more or less sides, but the sides still form an edge around the sides of the card. 
         [0003]    A user of the card may identify the card by viewing the indicator on the edge of the card. For example, a user may view projections on at least one edge of the card when the faces of the card cannot be viewed, or otherwise identified, such as for example when the card is located within a wallet or a purse. A user may also be able to identify the card by touching the indicator when the indicator cannot be seen. For example, a user may identify a card by touching the edge of the card and identifying the type of projections (i.e., ridge, groove, dimple, or the like), height of the projections, or the spacing of the projections on the edge of the card. The ability to identify the card simply through touch may be useful to visually impaired users for differentiating between types of cards that may otherwise be difficult to identify without the projections.

     DETAILED DESCRIPTION 
       [0053]    Embodiments of the present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout. 
         [0054]      FIG. 1  illustrates a flowchart for manufacturing a card with an indicator, in accordance with one embodiment of the invention. As illustrated by block  10  in  FIG. 1 , a core layer for the card is procured by purchasing or creating the core layer. In one embodiment of the invention, melted plastic is molded into a thin plastic sheet. For example, the core layer may be formed through an extrusion molding process. In other embodiments the core layer may be molded using other molding processes. Instead of molding the core layer from plastic, in some embodiments, the core layer may be formed from another material using another process. The core layer may be formed from a particular color, or otherwise, painted, printed on, or the like, to display a color or design (e.g., logo, word, or the like) that a customer desires on the card. In some embodiments of the invention there may be one or more core layers. 
         [0055]    As illustrated by block  20 , one or more outer layers are procured by purchasing or creating the one or more outer layers. In one embodiment the outer layers are also created from plastic, for example also through an extrusion process. In other embodiments, the outer layers may be created through other processes. The outer layers may be painted or printed (e.g., ink printed, laser printed, screen printed, or the like) with the color scheme and wording desired by the customer. In some embodiments, at least a portion of an outer layer is clear, and the color scheme of the card is created on the core layer, as previously described. In some embodiments, the core layer does not exist and only the outer layers are used to create the card (e.g., a front layer and back layer). In still other embodiments of the invention, there may be multiple outer layers on either side of the faces of the core layer. 
         [0056]    In some embodiments, as illustrated by block  30  in  FIG. 1 , an information storage feature may be associated with the core layer or the one or more outer layers. The information storage feature may be a magnetic strip, barcode, radio frequency identifier (RFID) tag, optical storage device, smart card chip, or other like information storage feature. For example, one of the outer layers may be overlaid with a magnetic strip when the card is a financial institution card (e.g., credit card, debit card, gift card, or the like), an identification card, or a security card. In other examples, a bar code may be printed on the core layer or the outer layer. In still other examples, the RFID tag, optical storage device, or smart card chip may be affixed to the core layer or the outer layer. The process of associating the information storage feature to the card may be done before or after the core layer and/or the one or more outer layers are secured together. 
         [0057]    As illustrated by block  40  in  FIG. 1 , the layers are secured together to form a sheet stock (e.g., sheet blank). In one embodiment of the invention, the layers may be laid on top of one another and placed into a press that may heat and apply pressure to the layers to form the sheet stock. In other embodiments of the invention, a roller system may be used to form the layers together. For example, outer layers on rolls may be laminated to a core layer using heat and pressure as the outer layers are applied to the core layer. In some embodiments the layers may include a core layer, a front outer layer, and a back outer layer. In other embodiments of the invention the layers may only include a front layer and a back layer (or core layer). In still other embodiments, there may be multiple front layers and back layers. The present invention covers any number of different layers that are formed together to create the sheet stock. 
         [0058]    Block  50  of  FIG. 1  illustrates that the sheet stock is cut into card stock (e.g., one or more card blanks), with the indicator on the edge of the card stock. In some embodiments of the invention the sheet stock is cut or stamped using one or more tools, such as dies, that form the card stock with the indicators on at least a portion of the edge of the card stock. The dies used to form the card stock may be plates or other like tools that have an outer die edge with the same projections and dimensions as described below with respect to the card stock. In this way a die may be a mirror image of the card stock and be used to punch or cut out card stock with the same type of projections and projection dimensions as described herein with respect to the card stock. In other embodiments of the invention, the dies used to form the card stock may have a cavity (e.g., die cavity) with an inner die edge having the opposite projections and dimensions as described herein with respect to the card stock. In this way a die may have the opposing image of the card stock and be used to punch or cut out the card stock with the desired type of projections and projection dimensions as described herein with respect to the card stock (e.g., see  FIGS. 2A ,  2 B, and  3 ). In still other embodiments the dies may be one or more blades (e.g., die blades) that punch or cut one or more of the edges of the card stock as described herein. In still other embodiments of the invention the dies may be cooperating dies that work together to form the card stock with the desired edge indicators. For example, in one embodiment a die punch with die punch projections having the mirror image of the desired card stock may work in connection with a die cavity with die cavity projections that are opposite the die punch projections and desired card projections, such that the die punch and die cavity stamp out the card stock with the desired card projections. Regardless of the type of dies used to form the card stock, the dies used in the present invention are configured to punch or stamp the card stock with edge indicators, as described herein. In other embodiments of the invention the sheet stock may be cut using other types of cutting devices. 
         [0059]    As illustrated in block  60  of  FIG. 1 , at least one security feature may be attached to the card stock, if necessary. The security features may include a signature strip, hologram, photo, security tape, or other like security feature. In some embodiments one or more of these security features may be incorporated into the core layer or one or more outer layers of the card before or after various steps within the card manufacturing process described herein. 
         [0060]    The manufacturer may store the card stock until the card stock is ready for personalization, the card stock may be shipped to the institution that ultimately provides the card to the customer, or the card stock may be sent to another party for additional manufacturing. In some embodiments, the card stock is ready for use by an institution after the card stock is cut from the sheet stock. For example, in the case of reward cards or gift cards, the card stock may be shipped to a store, at which the store may ultimately associate the card with a customer or dollar amount. In an example where the card is an identification card, the card stock may be sent to a secure agency that associates the card with a person, for example prints or affixes a photo on the card stock, and/or stores data on the information storage feature (e.g., magnetic strip or RFID tag). In other embodiments of the invention, for example, in the case of financial institution cards, the card stock is sent to a secure location for additional processing of the card with personalized financial information. 
         [0061]    As illustrated by block  70  in  FIG. 1 , personalized information may be associated with the card stock. As previously discussed this may include printing photo identification onto the card, with respect to an identification card or security card. In other embodiments of the invention, the personalized information may be an account number or customer name that is printed, stamped, embossed, or otherwise attached to or formed into the card. For example, with respect to financial institution cards (e.g., credit card, debit card, and the like) a customer name, account number, and expiration date may be embossed into the card stock to form the card. 
         [0062]    Block  80  of  FIG. 1  illustrates that information may also be stored on or associated with the information storage feature of the card stock. For example, with respect to financial institution cards, account information, customer information, financial institution communication information (e.g., where to route requests for purchases), or other like information may be stored on a magnetic strip of the card. In other embodiments, for example with respect to gift cards, prepaid cards, or the like, the dollar amount of the card may be stored on the magnetic strip of the card. In still other embodiments of the invention, for example with respect to security cards or identification cards, the magnetic strip may hold information about security clearance, personal identification information about the card holder, communication information to allow access to a database that contains information, access information to allow access to a secure location, or other like information. In other embodiments, the information stored may be stored on information storage features other than a magnetic strip, as previously discussed. With respect to reward cards, the information storage feature may be a bar code that is associated with a particular customer in a database in order to provide rewards to the customer based on the customer&#39;s purchases or the customer&#39;s profile. Embodiments of the present invention may create cards with indicators, on which various types of information may be stored or associated with the information storage feature of the card. 
         [0063]      FIG. 2A  illustrates one embodiment of a plan view of the edge of a tool (e.g., die) used to create a card indicator  400  (e.g., projections  402 ) on an edge of a card, in accordance with an embodiment of the invention. As illustrated in  FIG. 2A , the tool  200  (e.g., die) has a tool edge  202  (e.g., die edge) with tool projections  204 , such as a plurality of inverted half circles  210  with tool peaks  212  and tool troughs  214  that are used to form the card indicator  400  on the card edge  302  of the card stock  300 . The tool edge  202  is similar to a sawtooth, serrated knife, triangular point, or other like edge that forms the half circle projections  410  on the card edge  302 . In some embodiments of the invention, the half circle projections  410  have projection peaks  412  and projection troughs  414 . The projection peaks  412  may have rounded ends in some embodiments (as illustrated in  FIG. 2A ). The projection troughs  414  may have pointed troughs in some embodiments (as illustrated in  FIG. 2A ). 
         [0064]    In some embodiments of the invention the tool edge  202  and card edge  302  described with respect to  FIG. 2A  are reversed, as illustrated in  FIG. 2B . As such, the tool  200  (e.g., die) has a tool edge  202  with tool projections  204 , such as a plurality of half circles  220  projecting from the tool  200  with tool peaks  222  and tool troughs  224  that are used to form the card indicator  400  (e.g., projections  402 ) on the card edge  302  of the card  300 . The tool edge  202  is used to form the sawtooth projections  420  on the card edge  302 . The tool edge  202  in  FIG. 2B  is similar to a half-circle edge, or other like edge that forms the sawtooth projections  420  on the card edge  302 . In this embodiment the sawtooth projections  420  have projection peaks  422  and projection troughs  424 . The projection peaks  422  of the card edge  302  are illustrated as having a point, while the projection troughs  424  are substantially half circles. 
         [0065]    In some embodiment of the invention, as illustrated in  FIG. 3 , the tool  200  (e.g., die) has a tool edge  202  with tool projections  204 , such as rounded features  230  projecting from the tool  200 , with rounded tool peaks  232  and rounded tool troughs  234  that are used to form the card indicator  400  on the card edge  302  of the card  300 . The tool edge  202  is used to form the rounded projections  430  on the card edge  302 . In this embodiment the rounded projections  430  have projection peaks  432  and projection troughs  434  that are both rounded for forming a card edge  302  that is in the shape of a sine wave, such that the projection peaks  432  and projection troughs  434  have the same or similar dimensions. 
         [0066]    In other embodiments of the invention, the tool peaks and tool troughs may have other shapes not explicitly described herein that produce projection peaks and projection troughs in the card edge  302  that are not explicitly described herein. 
         [0067]    Regardless of the various configurations of the tool edge  202 , the tool  200  is configured cut sheet stock into card stock  300 . The tool  200  cuts sheet stock such that the card edge  302  of the card stock  300  has a projection  402  over at least a portion of the card edge  302 . 
         [0068]      FIG. 4  illustrates a perspective view of a financial card  500 , such as a debit card or credit card, made from card stock  300 . In the illustrated embodiment the financial card  500  has a first side  502 , a second side  504 , a third side  506 , and a fourth side  508 , comprising a surface of the card extending around the outside of the card forming the edge  510  of the card.

         [0071]      FIG. 7  illustrates one embodiment of the first side  502  of the financial card  500  with the semi-circular projections  410 . In the illustrated embodiment the first side  502  is the top edge of the financial card  500 , however, in other embodiments of the invention the first side  502  may be another side of the financial card  500 . 
         [0072]      FIG. 8  illustrates one embodiment of the second side  504  of the financial card  500  with the semi-circular projections  410 . In the illustrated embodiment the second side  504  is the right edge of the financial card  500 , however, in other embodiments of the invention the second side  504  may be another side of the financial card  500 . 
         [0073]      FIG. 9  embodiment of the third side  504  of the financial card  500  with the semi-circular projections  410 . In the illustrated embodiment the third side  506  is the bottom edge of the financial card  500 , however, in other embodiments of the invention the third side  506  may be another side of the financial card  500 . 
         [0074]      FIG. 10  illustrates one embodiment of the fourth side  508  of the financial card  500  with the semi-circular projections  410 . In the illustrated embodiment the fourth side  508  is the left edge of the financial card  500 , however, in other embodiments of the invention the fourth side  508  may be another side of the financial card  500 . 
         [0075]    In other embodiments of the invention, instead of the semi-circular projections  410  illustrated with respect to  FIGS. 4-10 , the financial card  500  (or other type of card) may have projections  402  of different shapes, such as the rounded projections  430  illustrated in  FIGS. 18-24 . As illustrated in  FIGS. 18-24 , and as previously described with respect to  FIG. 3  the edges on the sides  502 ,  504 ,  506 ,  508  of the card  500  may have rounded projections  430  that create a card edge  302  that has the shape of a sine wave. 
         [0076]    In the present invention, the card indicator  400 , for example the projections  402  on the card edge  302  of the card stock  300 , may be located over the entire card edge  302  of the card stock  300  or along only a portion of the card edge  302  of the card stock  300 . Along with the different types of projections  402 , the location of the projections  402  on the card edge  302  may allow a user to differentiate one type of card from another type of card. In order to create the different types of projections  402  along different portions of the card edge  302  of the card stock  300 , the tool edge  202  of the tool  200  is configured with tool projections  204  (e.g., projections on the cutting or punching edge of the tool) that are used to create the desired type of card edge  302  on the card stock  300 . Therefore, in some embodiments of the invention the tool projections  204  are formed around substantially the entire tool edge  202  of the tool  200 , such that the card stock  300  ultimately formed from the sheet stock comprises a card indicator  400  around the entire card edge  302 , as is illustrated in  FIGS. 5-10  and  18 - 24 . In other embodiments of the invention, the tool projection  204  is formed on only one or more sides or corners of the tool  200 , such that the card stock  300  ultimately formed from the sheet stock comprises a card indicator  400  on one or more of the sides or corners of the card stock  300 , as illustrated in  FIGS. 11A  (e.g., projections  402  on the first side  502  and third side  506 ),  11 B (e.g., projections  402  on the second side  504  and fourth side  408 ), and  11 C (e.g., projections  402  on the corners  516 ). In some embodiments the tool projection may be located along the entire length, or along only a portion of the length, of the one or more sides or corners of the tool  200 , such that the card stock  300  ultimately formed from the sheet stock comprises a card indicator  400  on a portion, or the entire length, of the sides or corners of the card stock  300 . 
         [0077]      FIGS. 12 and 13  illustrate two embodiments of the card, wherein the projections  402  are spaced apart at different intervals along at least a portion of the card edge  302 . The reference letter H illustrates the height of the projections  402  from the peak of the projections  402  to the trough of the projections  402 . The reference letter W illustrates the width of the projections  402  from a first peak of a projection  402 , to a second peak of a projection  402  adjacent the first peak. In some embodiments of the invention the peak of the projections  402  will not extend greater than 0.003″ H above the trough of the projections  402 . However, in some embodiments of the invention the difference may be less than or equal to 0.005″, less than or equal to 0.010″, less than or equal to 0.020″, less than or equal to 0.03″, less than or equal to 0.04″, less than or equal to 0.05″, less than or equal to 0.1″ or the like, or otherwise, be between two or more of these distances, or outside of these distances. 
         [0078]    The projections  402  may also be spaced apart a number of different distances. In one embodiment of the invention, a first projection peak  522  may be located adjacent a second projection peak  524  located at a distance W of approximately 0.003″. The distance W between a first peak  522  and a second peak  524 , in other embodiments may be approximately 0.037″, as illustrated in  FIG. 12 . The distance W between a first peak  522  and a second peak  524 , in other embodiments may be approximately 0.16″, as illustrated in  FIG. 13 . In still other embodiments of the invention, the distance W between a first peak  522  and a second peak  524  may be between 0.003″ to 0.037″, less than or equal to 0.005″, less than or equal to 0.010″, less than or equal to 0.020″, less than or equal to 0.030″, less than or equal to 0.040″, less than or equal to 0.050″, less than or equal to 0.1″, less than or equal to 0.2″, or the like, or otherwise, be between two or more of these distances, or outside of these distances. The differences in the distances H and W described with respect to  FIGS. 12 and 13 , apply equally to the projections  402  that are illustrated in the other figures herein. Therefore, in some embodiments of the invention the distances described with respect to the projections  402  above may apply to the projections  402  illustrated in  FIGS. 2-11C , and  14 - 24 , as well as other types of projections  402  not specifically described herein. 
         [0079]    Furthermore, the dimensions described above with respect to the card projections  402  on the card stock  300 , may apply to the tool projections  204  on the tool  200  that are used to create the card projections  402  on the card stock  300 . 
         [0080]      FIG. 14  illustrates another embodiment of the invention, wherein the projections  402  are v-shaped projections  470  on at least a portion of the edge  302  of card stock  300 .

In other embodiments of the invention, the trapezoidal projections  480  may be located along a portion of one or more sides of the cards (e.g., a first side  502 , a second side  504 , a third side  506 , or a fourth side  508 ). 
         [0082]      FIG. 16  illustrates another embodiment of the invention, wherein the projections  402  are sine wave projections  490  in the shape of a sine curve. In the embodiment illustrated in  FIG. 16  the sine wave projections  490  are located on the corner  516  of the card stock  300 , and/or along two perpendicular sides of the card stock  300 . In other embodiments of the invention, the sine wave projections  490  may be located along a portion of one or more sides of the cards (e.g., a first side  502 , a second side  504 , a third side  506 , or a fourth side  508 ). The sine wave projections  490  are further illustrated in  FIGS. 18-24 . 
         [0083]    In still other embodiments of the invention the projections  402  may be of any type of shape and size. Furthermore, the projections  402  may either project from a surface of the edge  302  of the card stock  300 , or project into the edge  302  of the surface of the card stock  300 . The projections  402  (or the reverse image of the projections  402 ) illustrated and described with respect to  FIGS. 14-16 , may also illustrate and describe the tool projections  204  (or the reverse image of the tool projections  204 ) that are used to create the card edges  302  of the card stock  300 . 
         [0084]      FIG. 17  illustrates another embodiment of the invention wherein the card is a mini-card  600 , which is configured with an aperture  620  therethrough in order to allow for attachment to a key-ring.
