CROSS-REFERENCE TO RELATED APPLICATION 
     This application claims the benefit of and is a non-provisional of U.S. Provisional Application No. 60/680,826, filed on May 12, 2005, which is assigned to the assigner hereof and hereby expressly incorporated by reference in its entirety for all purposes. 
    
    
     BACKGROUND 
     This disclosure relates in general to cards that store information. More specifically, but not by way of limitation, this disclosure relates to data cards used with card readers, proximity scanners, and/or similar devices. 
     Passengers may gain entry to transit systems by using fare cards. Over time, transit systems have replaced their fare collection equipment and upgraded their data storage technologies. This has resulted in transition periods where a particular transit system may utilize different fare collection equipment at different points within the system. Different and incompatible fare collection equipment may force passengers to carry multiple fare cards in order to use the transit system. 
     In addition, an individual transit system may be part of a larger transportation network. To reach their destinations, passengers may need to cross boundaries between transit systems that utilize different types of fare cards. In these situations, passengers may be required to carry multiple fare cards, each intended for use in a different part of the transportation network. 
     SUMMARY 
     In one embodiment, the present disclosure provides a fare card for storing information in a plurality of different ways for use in a transit system. The fare card includes a card body that has at least a first region and a second region. The first region is located adjacent to an edge of the card body and has a first thickness. The second region has a second thickness that is different than the first thickness. A first data storage element for storing fare information is included in the first region, and a second data storage element is included in the second region. 
     In another embodiment, the present disclosure provides a data card for storing information in a plurality of different ways. The data card includes a card body that has at least a first region and a second region. The first region is located adjacent to an edge of the card body and has a first thickness.

     DETAILED DESCRIPTION 
     The ensuing description provides preferred exemplary embodiment(s) only, and is not intended to limit the scope, applicability or configuration of the invention. Rather, the ensuing description of the preferred exemplary embodiment(s) will provide those skilled in the art with an enabling description for implementing a preferred exemplary embodiment of the invention. It being understood that various changes may be made in the function and arrangement of elements without departing from the spirit and scope of the invention as set forth in the appended claims. 
     Specific details are given in the following description to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. For example, circuits may be shown in block diagrams in order not to obscure the embodiments in unnecessary detail. In other instances, well-known circuits, processes, algorithms, structures, and techniques may be shown without unnecessary detail in order to avoid obscuring the embodiments. 
     Referring first to  FIG. 1A , a side-sectional view of an embodiment of a data card  100 - 1  is shown. This embodiment of the data card  100 - 1  comprises a card body  104  that may be formed either from a single piece of material or from two or more layers of material. The material is commonly plastic and/or paper but may include other substances that are durable and capable of holding a shape. In addition, the material may be transparent or opaque as required to display pictures and/or writing. 
     The card body  104  is intended to be portable and may be approximately the size of a consumer credit card. Other embodiments may be approximately the size of identification cards, fare cards, membership cards, card keys, passports, or stored value cards. Other embodiments could have other configurations and sizes. 
     In this embodiment, the card body  104  includes a first region  108  and a second region  112 . The regions  108 ,  112  may perform different functions and may be either rigid or flexible depending upon their intended use. In a particular embodiment, for example, the first region  108  might be used with a magnetic stripe card reader/writer. Thus, it might be flexible and specially designed for swiping operations. The second region  112 , on the other hand, might be substantially more rigid than the first region  108  in order to protect an integrated circuit and/or an antenna. 
     Applications of the data card  100 - 1  have regions  108 , 112  of particular thicknesses. The thickness may be a physical constraint or may be related to durability and length of service considerations. For example, an ATM machine may only accept cards with a particular thickness. Alternatively, a data card manufacturer may design a card to last for a short period of time. Data cards intended to last for long periods of time may be thicker and more rigid than disposable cards that provide only a few uses. Thus, thickness may be an important consideration in determining whether a data card is suitable for a specific application. 
     To provide flexibility, regions of the card body  100 - 1  have different thicknesses. Specifically, the first region  108  has a first thickness  116  and the second region  112  has a second thickness  120 . The two thicknesses are generally selected to conform with popular card standards, including ISO 7810 (identity cards) and ISO 15457 (thin flexible cards). Other embodiments of the data card  100 , however, may incorporate additional aspects of commercial and international card standards to further enhance data card functionality. Further, some embodiments may not conform to any standard, but are designed to work with proprietary readers. Throughout this specification card reader/writers may be referred to as being a reader or reading equipment, but it is to be understood that the reader may also write to the data card. 
     In an exemplary embodiment, the first thickness  116  is from about 250 um (10 mils) to about 305 um (12 mils) thick and is designed for use with magnetic thin card reading equipment. The second thickness  120  is approximately 760 um (30 mils) thick and conforms to thickness specifications of ISO 7810, ID-1 format. In other embodiments, the first thickness  116  at its maximum may comprise any whole number between 200 um (8 mils) and 381 um (15 mils) and the second thickness  120  at its maximum may include any whole number between 600 um (25 mils) and 1000 um (40 mils). 
     Many combinations of the first thickness  116  and the second thickness  120  are possible in various embodiments. These combinations permit card manufacturers and card sellers to target the needs of their customers. Thus, a transit system operator may deploy a data card that allows passengers to swipe the first region  108  of the card body through a turnstile in a subway system and later insert the second region  112  into a vending machine to make purchases, for example. Alternatively, combination data cards might be offered by different businesses or government entities to meet customer demands. For example, a fare card could be paired with an identification card or an RFID toll card. In each case, however, the first thickness  116  and the second thickness  120  enable a single data card  100 - 1  to be used with a wide range of reader equipment in many different applications. 
     A first data storage element  124  is included in the first region  108  for interacting with external reader/writer systems. The second region  112  has a second data storage element  128 . As shown, the data storage elements may be different. For example, the first data storage element  124  may be a magnetic stripe (“magstripe”) and the second data storage element  128  may be an integrated circuit. Other embodiments, however, may include the same type of data storage element in both the first and second regions. The data storage elements may comprise magnetic stripes, optical bar codes, integrated circuits with external contacts, integrated circuits with antenna configurations, and passive or active RFID tags. Integrated circuit storage elements may be further coupled to microprocessors and digital memory circuits to provide additional capabilities. 
     A magnetic loop antenna  132  enables embodiments of the data card to wirelessly interact with card reading equipment. The magnetic loop antenna  132  may have different lengths and geometric arrangements for particular applications. For example, some embodiments of the data card  100 - 1  may include a second data storage element  128  that is an active RFID tag. In this case, the RFID tag would be activated by exposing the magnetic loop antenna  132  to electromagnetic radiation from an RFID transceiver. Standard RFID activation frequency ranges include low-frequency (125 or 134.2 KHz), high-frequency (13.56 MHz), UHF (868 to 956 MHz) and microwave (2.45 GHz) in various embodiments. Thus, embodiments of the data card may include a magnetic loop antenna  132  that is specifically designed to receive the wireless communication signals. 
     Other embodiments of the data card  100 - 1 , for example, might include a second data storage element  128  that is an integrated circuit coupled to a magnetic loop antenna  132 . This configuration might provide contact-less smartcard functionality in accordance with ISO 14443 or some other standard. As an example, the card might act as a stored value card that employs data encryption technology for secure wireless transactions with a host system. 
     In some embodiments, the first data storage element  124  operates independently from the second data storage element  128 . Other embodiments, however, may include an electrical connection  130  between the elements that facilitates the exchange of information. For example, an embodiment comprising a first data element  124  that is a magnetic stripe and a second data storage element  128  that is an integrated circuit might also include an electrical connection  130  between the elements such that the integrated circuit could read data from or write data to the magnetic stripe to reprogram it. Where there is the ability to reprogram one data storage elements from the other, both data storage elements could be synchronized. Further embodiments might include a first data storage element  124  that is an integrated circuit coupled to a microprocessor and a second data storage element  128  that is an integrated circuit. An electrical connection  130  might couple the data storage elements such that both could be programmed by the microprocessor. 
     Referring to  FIG. 1B , a side-sectional view of an embodiment of a data card  100 - 2  having surface mounted electrical contacts  152  is shown. This embodiment illustrates a second data storage element  128  that is an integrated circuit. The second data storage element  128  is disposed in the second region  112  of the data card and can be protected by the second thickness  120 . The second data storage element  128  can be accessed by a card reader through electrical contacts  152 . 
     This embodiment also shows a first data storage element  124  that is a magnetic stripe  124 . The magnetic stripe  124  is located at an offset  156  distance from an edge of the card body. Placement of the first data storage element  124  in relation to an edge of the card body  104  allows proper alignment of the magnetic stripe  124  when the data card is swiped through a card reader/writer. In an exemplary embodiment, the first data storage element  124  is a 9.53 mm (0.375 inch) magstripe and is offset  156  by a distance of about 5.66 mm (0.223 inch) from the edge of the card body  104 . Other offsets  156  from the edge of the card body  104  may be selected to accommodate a variety of card reading/writing equipment. 
     Referring next to  FIG. 1C , a side-sectional view of an embodiment of a data card  100 - 3  with a removable cover  136  is shown. The removable cover  136  connects to the card body  104  with a fastener  148 . The fastener  148  may comprise plastic tabs, a perforated seam, an adhesive strip, a snap assembly, or other means of attachment. Depending upon the fastener  148  selected, it may or may not be possible to reattach the removable cover  136  to the card body  104 . Thus, some embodiments may include tear-away or break-away covers while other embodiments may have fasteners that permit the cover to remain attached and be flipped-back to its original position. In one embodiment, the fastener allows removal of the cover  136 , which can be reattached by snapping the fastener back in place on the card body  104 . There may be a non-permanent adhesive on the cover  136  to allow sticking it into place on the card body when the first data storage element  124  is not needed. 
     The removable cover  136  protects the first data storage element  124  until it is needed. In the embodiment shown, the removable cover  136  also increases the first thickness  116  so that it generally matches the second thickness  120 . This results in a uniform thickness throughout the card body  104  and may facilitate manufacturing, distribution and use of the data card in one embodiment. For example, uniform thickness may facilitate use with automated test equipment or dispensing devices such as vending machines. 
     With reference to  FIG. 1D , a side-sectional view of an embodiment of a data card  100 - 4  with a retractable cover  140  is shown. In this embodiment, the retractable cover  140  rotates about an axis running along an edge of the card body  104 . A fastener  144  such as a hinge, pin, or swivel joint attaches the retractable cover  140  to the card body  104 . In one embodiment, the fastener  144  is made of the same material as the card body  104 , but is thin enough to allow the material to act as a hinge. The retractable cover  140  may be opened to a position that exposes the first data storage  124  element and later closed to cover and protect the first data storage element  124 . Adhesive on the retractable cover  140  may allow the cover  140  to remain in the close position without passing adhesive to first region  108 . 
     Referring to  FIG. 2A , a plan view of an embodiment of a data card  200 - 1  is shown. This embodiment illustrates a card body  104  with length  208  and width  204  dimensions where the length dimension is greater than the width dimension. In an exemplary embodiment, the length  208  and the width  204  conform to the ID-1 format of ISO 7810. Thus, the length  208  is approximately 86 mm (3.39 inches) and the width  204  is approximately 54 mm (2.13 inches), for example. Other data card embodiments, however, may be directed to different standards or different data card applications. Thus, the length  208  and width  204  dimensions of the card body  104  may be varied to meet different card requirements. 
     The present embodiment includes electrical contacts  152  mounted on the surface of the card body  104  that connect to a second data storage element located directly below the electrical contacts  152 . In other embodiments, the data storage element is not directly below the electrical contacts  152 , but the data storage element is electrically coupled to the electrical contacts  152 . The electrical contacts  152  enable a card reader to access data stored by the second data storage element. In an exemplary embodiment, the layout of the electrical contacts  152  and their position on the data card  104  conform to the ISO 7816 standard describing contact smart cards. Other embodiments, however, may use customized electrical contacts  152  that may be attached at custom locations on the data card. 
     A first region width  212  is also shown in the present embodiment. The first region width  212  may vary with respect to the card body width  204  and assume different percentages of the card body width  204 . In an exemplary embodiment, the first region width  212  may be approximately 33% of the card body width  204 . However, as used in different applications, the maximum first region width  212  may be any whole percentage from 15% to 41% of the card body width  204 . 
     Referring to  FIG. 2B , a plan view of an alternative embodiment of a data card  200 - 2  is shown. In this embodiment, a third data storage element  216  has been added to the second region  112 . This configuration further enhances the functionality of the data card. For example, a data card in the present embodiment might include a first region  108  serving as a magnetic thin card and a second region  112  that acts both as a standard magnetic stripe credit card and as a contact smartcard. 
     With reference to  FIG. 2C , a plan view of a further embodiment of a data card  200 - 3  is shown. In this embodiment, the first region  108  comprises a first data storage element  124  that is a magnetic stripe. The second region  112  includes a second data storage element  128  that is an integrated circuit coupled to a magnetic loop antenna  132 . The magnetic loop antenna  132  is fully contained within the second region  112  and may vary in length and geometry based upon its intended application. For example, this configuration might permit transit passengers to pass between different fare collection systems in a transit network or to pass through different segments of a transit system. 
     Referring to  FIG. 2D , a plan view of an additional embodiment of a data card is shown. This embodiment illustrates surface mounted electrical contacts  152  that attach below to a first data storage element. A second data storage element  128  that is an integrated circuit coupled to a magnetic loop antenna  132  is also shown. This embodiment may represent a customized application intended for use during a transition period, for example. An electrical conductor may be included for synchronizing the two data storage elements or otherwise sharing information between them. Other embodiments may not couple together the data storage elements. 
     While the principles of the disclosure have been described above in connection with specific apparatuses and methods, it is to be clearly understood that this description is made only by way of example and not as limitation on the scope of the invention.
