`HIGH SECURITY DATA CARD
`
`BACKGROUND
`
`1.
`
`The Field of the Invention.
`for portably
`This
`invention relates
`to “apparatus
`containing data. More particularly,
`the present invention
`relates to devices which store data in multiple formats in
`one physical structure.
`
`2.
`
`The Prior Art.
`
`Currently available portable data-containing devices
`include plastic cards that are used to carry and transmit
`financial, medical and other data.
`Such cards are also
`
`used as credit cards and debit cards,
`
`in addition to other
`
`uses.
`Currently, machine
`readable data is carried on
`portable data cards in magnetic strips which require linear
`motion to read the data stored in the magnetic strip, or in
`electronic circuits from which the data is read using a
`digital protocol, or in linearly accessible optical storage
`formats which require linear movement
`in relation to the
`
`that are
`forms
`in optical
`card to read the data, or
`rotatably accessible which require rotational movement
`in
`relation to the card to read the data on the card.
`
`Currently, there are financial transaction cards, such
`as credit
`cards, which possess both a data carrying
`magnetic strip and a data carrying electronic circuit which
`
`10
`
`15
`
`20
`
`25
`
`are used to identify the bearer of the card.
`
`These cards
`
`30
`
`are capable of carrying data in two mediums.
`The limited
`data capacity of
`these dual medium cards requires that
`additional information must be obtained to verify that the
`user has the proper authority to use the card.
`
`is,
`transaction cards
`financial
`Fraudulent use of
`unfortunately,
`a
`common
`occurrence.
`MasterCard
`International, of Purchase, N.Y.
`reported that
`in 1995,
`worldwide,
`9 cents of every $100 dollars was lost to fraud.
`This represents roughly $400 million out of $470 billion in

`
`transactions. It has been estimated that credit card fraud
`
`totals over $1 billion every year.
`
`At present,
`
`to verify that a user is authorized to
`
`make a transaction with such a financial transaction card,
`a merchant must first verify the card’s validity through a
`computer network
`(e.g.,
`a
`computer network known
`as
`
`vISAnet, a computer network provided by American Express,
`or some other credit card issuer) associated with the card,
`
`separate physical
`
`information must
`
`then be collected and
`
`10
`
`for example signatures compared
`compared by the merchant,
`to the authorized signature provided on the card, or other
`
`15
`
`20
`
`forms of picture containing identification which
`
`are
`
`compared to the user. Disadvantageously, even the limited
`protection provided by comparing an authorized signature or
`picture provided on a financial
`transaction card becomes
`
`unavailable in a computer based (also referred to as an
`
`“online”)
`
`transaction, where
`
`there
`
`are
`
`no merchant
`
`this comparison.
`to make
`personnel physically present
`Recent surveys have suggested that credit card fraud my be
`up to twelve times more common in “on-line” transactions
`
`than in “in person” transactions. Additionally, “on-line”
`retailers often have to bear the liability for this fraud,
`while the credit card companies generally absorb these
`
`costs for traditional “in person” retailers that take fraud
`
`25
`
`prevention steps.
`
`In view of the foregoing, it will be appreciated that
`it would be
`an improvement
`in the art
`to provide a
`financial transaction device or system which eliminates the
`
`30
`
`need for using an additional identification card, and for
`comparison of signatures, while continuing to ensure that
`the user is authorized to make the transaction.
`
`Also currently,
`
`there are wallet sized cards known
`
`which contain optically accessible data stored in a format
`
`which does not require rotating the card. While this type
`of non-rotating optically accessible data card is capable

`
`of containing more data than a wallet sized card which
`stores data on a magnetic strip, it requires a specialized
`and proprietary reader for accessing the data, which reads
`the optically stored data in a linear fashion.

`
`BRIEF SUMMARY OF THE INVENTION
`
`In accordance with one aspect of the present invention
`a transaction card is provided, that combines in one device
`the
`capability to
`store magnetically
`encoded
`data,
`rotatably accessible optically stored data, and data stored
`in a circuit.
`In one preferred embodiment of the present
`invention, a financial transaction card is provided with at
`least one structure capable of containing magnetically
`encoded data, at
`least one structure capable of holding
`rotatably accessible optically stored data and at least one
`circuit. Preferably,
`there are at least three independent
`data sets, accessible through different data retrieval
`methods.
`The plurality of data
`sets
`are preferably
`separately encrypted, namely, each set is encrypted using
`a different standard.

`market.
`The existing technology is
`severely limited
`because of the lack of digital memory space on existing
`devices. Advantageously,
`in accordance with another aspect
`of
`the present
`invention, high capacity optical storage
`technology, such as digital versatile disc technology,
`is
`included many
`illustrative embodiments of
`the present
`invention and in many embodiments in combination with smart
`card chips.
`The high storage

`and ensuring the identify of
`the
`presenter
`of
`the
`card. Advantageously,
`illustrative
`embodiments of the present invention address the needs of
`various markets and applications and one illustrative card
`could function instead of requiring many different cards
`using existing technology. Moreover,
`in accordance with
`another aspect of the present
`invention,
`the illustrative
`embodiments of
`the present
`invention
`are backwards
`compatible and can be introduced and implemented with the
`existing credit
`card infrastructure which
`is
`already
`present in the marketplace.

`numerous security breaches including: being susceptible to
`falsified digital
`certificates
`and
`corrupted digital
`certificates;
`allowing stolen identities to be used by
`unauthorized third parties undetected; and reliance on a
`third party server which must be trusted by those who are
`transacting business over
`the
`Internet.
`The present
`invention advantageously does not rely on a third party
`server but rather all the necessary data resides on the
`illustrative cards of the present invention providing much
`more security than previously possible using server-based
`public key infrastructure systems.
`
`One preferred tri-format combination device of
`the
`present
`invention is particularly directed to reducing
`fraud in financial transactions. The separate data sets on
`the single card preferably contain different data and are
`separately accessible by different user
`inputs
`(such as
`personal identification numbers, machine readable physical
`information such as fingerprints, a photographic or digital
`image, or other biometric information).
`The information
`from the separate data sets can be compared by the system
`to verify the user’s identity and authorization to conclude
`the transaction.

`invention
`the present
`One preferred embodiment of
`includes
`a
`rotatably accessible optically stored data-
`containing structure.
`This feature adds a third data set
`
`capable of containing much larger amounts of data than the
`prior art devices, allowing the user’s machine readable
`physical information to be stored in the device. Machine
`readable physical
`information can include a photographic
`image,
`a
`fingerprint
`image,
`a
`retina image,
`or other
`biometric information that is physically unique to the user
`and can be recorded, or examined by a mechanical device.
`This information can be accessed by the machine reading the
`device and compared to information input by the user,
`to
`ensure
`identification and authenticity.

`DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
`Reference will now be made to the drawings wherein
`like structures will be provided with like reference
`designations.
`The invention is a device, anda system for
`using that device.
`One preferred use of a preferred
`embodiment of the invention can be used for reducing fraud
`in computer based transactions. Financial transaction card
`based
`fraud
`is
`especially problematic
`for
`on-line
`‘transactions, occurring up to 12 times more frequently than
`with in-person transactions.
`It is estimated that credit
`card
`fraud costs
`financial
`companies, merchants
`and
`customers over a billion dollars each year,
`in the United
`States alone.
`By providing a device and method that may
`reduce
`these
`amounts
`for both in-person and on-line
`transactions,
`the
`present
`invention
`represents
`a
`substantial improvement over the prior art.
`refer to the
`While the described embodiments will

`appreciated that alternative uses of both the device and
`method are included within the
`scope of
`the present
`invention.
`Some possible alternative uses include use as
`a medical data-containing device,
`as
`a data-containing
`device and system to control access to secure areas, as
`well
`as other uses
`for
`a data-containing device
`and
`authorization system for other types of transactions, known
`or readily ascertainable to those skilled in the art that
`are included within the scope of the present invention.

`of
`numeral 10.
`The planar member can be constructed of any
`material
`used
`for making data-containing cards,
`the
`preferred construction will result in a surface hardness at
`least equal to that of polycarbonate.
`At
`least one structure associated with the planar
`member 10 is capable of containing magnetically encoded
`data.
`In the embodiment shown in Figure 1,
`this structure
`capable of containing magnetically encoded data
`is a
`magnetic strip 12. The
`information encoded on magnetic
`strip 12 contains at
`least one data set.
`The preferred
`structure capable of containing magnetically encoded data
`complies with ISO standard ISO 4909, hereby incorporated
`herein in its entirety by this reference, allowing the card
`to be used as a credit card or as a debit card.
`
`Associated with the planar member 10 is at least one
`circuit.
`In the embodiment shown in Figure 1, this circuit
`is represented by a box, generally indicated at 14.
`The
`preferred circuit
`is an integrated circuit;
`installed so
`the card and circuit comply with ISO standards ISO 7816(1-
`10), hereby incorporated by this reference in its entirety,
`or ISO 14443, hereby incorporated by this reference in its
`entirety; allowing the invention to function as what
`is
`
`commonly referred to in the industry as a “smart card.”
`The circuit 14 contains a data set, is capable of receiving
`further data input
`to it, processing that
`further data
`based on the data set already contained in the circuit, and
`then outputting additional data based upon that processing.
`The original dataset,
`a modified dataset based upon the
`processing, or both may be retained by the circuit 14 after
`output.
`It will be appreciated that various methods known,
`or readily ascertainable to those skilled in the art may be
`used to receive and output data by the circuit 14, and all
`such methods are within the scope of the present invention.

`the planar member
`containing machine readable rotatably accessible optically
`stored data through the bottom planar surface of planar
`member 10.
`A data set is contained in the structure for
`containing machine readable rotatably accessible optically
`stored data.
`
`Figures
`
`2
`
`and
`
`2A
`
`show the
`
`first
`
`illustrative
`
`embodiment of
`the device with structures that allow the
`machine readable rotatably accessible optically stored data
`to be accessed by a compact disc drive or other drive, such
`as a digital versatile disc drive. The side view of Figure
`2
`shows ridges 20 which protrude from the bottom planar
`surface of
`the planar member 10.
`Figure 2A shows
`the
`ridges 20, and the hole 16 from the bottom planar surface.
`The ridges 20,
`as
`shown in Figures 2 and 2A, allow the
`planar member 10, which is longer than the diameter of a
`miniCD to rotate in a compact disc drive.
`Alternative structures which allow the planar member
`10 to rotate in a compact disc drive/digital versatile disc
`drive are represented by Figures 3 and 4.
`Figure 3 shows
`an embodiment of the device in which the planar member 10
`is shaped as a card with curved first and second edges.
`The length of the planar member 10, shown in figure 3 at L,
`equals the diameter of a miniCD,
`the center hole 16 allows
`planar member 10 to be installed in compact disc drive,
`where the curved edges and the length allow it to rotate in
`the miniCD portion of the compact disk drive.
`Figure 4
`shows an embodiment of the device where the planar member
`10 is sized as a miniCD,
`this allows the planar member 10
`to rotate in a compact disk drive. Other structures and
`methods
`for
`achieving this
`rotation will
`be
`readily
`apparent
`to those skilled in the art and are within the
`
`scope of the present invention.

`include in the present
`inserted in cover 30, as shown in Figure 5.
`Cover 30 is
`preferably made of flexible plastic such as polyurethane.
`When planar member 10 is inserted in cover 30,
`the cover
`protects the circuit 14,
`and the structure capable of
`containing machine readable rotatably accessible optically
`stored data, an opening 32 in cover 30 allows the magnetic
`strip 12
`to be
`accessed by means
`for
`reading the
`magnetically encoded data. Alternatively,
`cover 30, as
`shown in Figure 5 can be constructed of material which
`allows electromagnetic waves to pass through.
`If circuit
`14
`is a “contactless” integrated circuit,
`such as those
`complying with ISO 14443,
`then circuit
`14 may also be
`accessed while planar member 10 is inserted in cover 30.
`It will be appreciated that while it
`is preferred to
`include a protective cover 30 with the planar member 10,
`that
`the present
`invention includes a tri-format device
`that does not feature such a removable protective cover.
`The cover 30, when it
`is used,
`is removable and many
`different
`embodiments of
`the invention can optionally
`utilize a removable cover, such as cover 30.
`Reference will now be made to Figure 5A to explain how
`chips with contacts called “contact chips” can be read with
`simple spindle modification.
`The
`illustrated structure
`design allows reading the chip circuits while the card is
`spinning.
`The key notch is representative of an alignment
`system that aligns the cards circuit leads with the CDROM’s
`spindle leads and they connect to the platter leads which
`in turn are connected to the computer circuitry. The notch
`can be spring loaded allowing non-notched CDs to be used.

`Reference will now be made to Figure 5B, which should
`be considered in tandem with Figure 5A,
`to alternatively
`explain how the card contacts would be aligned with the
`laser reading the cards data, determining its position on
`the disc and hence discs position relative to the contacts.
`The
`CDROM laser
`locates,
`assisted with software,
`the
`matched position of the cards contact leads and the spindle
`contacts.
`Once matched,
`the
`reader
`locks
`the
`card
`position, aligning contacts with the spindle contacts.
`This completes the circuit. The signal is sent through the
`leads to the stationary platter contacts,
`located above or
`below the spindle,
`then back and forth through the card
`through the platter which is connected to the computer
`circuits. This structures illustrated in Figures 5A and 5B
`can be oriented with either the top or the bottom of the
`spindle.

`
`In addition to the device that may be used to increase
`security in computer based transactions,
`the present
`invention also includes a system that may be used to reduce
`fraud in a computer based transaction. This system works
`by
`the
`transmission of
`information contained in the
`
`datasets to a receiving computer system, and the collection
`of confirmatory user data which is also transmitted to the
`receiving computer system.
`The receiving computer system
`then compares
`the confirmatory user data to standards
`contained in the datasets to verify the authorization of
`the user to make the transaction.
`If the confirmatory user
`data matches the standards, authorization is confirmed and
`
`10
`
`15
`
`allowed to proceed,
`the transaction is
`transaction is refused.
`
`otherwise

`
`In the preferred embodiment of the system, depicted in
`Figure 6,
`the transaction is a financial transaction of a
`
`credit or debit type.
`
`To make the transaction the card is
`
`inserted into a means for accessing the data, as shown in
`box 40.
`In a preferred embodiment,
`the means may be the
`user’s personal computer, although a proprietary reader,
`merchant computer system, or a proprietary card reader can
`be used, along with any other means that may perform the
`necessary functions. The user must then input information,
`as shown in box 42,
`to allow the means to compare the input
`information to information contained in the datasets.
`In
`
`the preferred embodiment,
`
`this information is one or more
`
`personal
`identification
`codes
`(associated with
`the
`independent datasets), which are entered into the means for
`accessing the data. After the means receives the personal
`identification codes,
`it verifies them and compares
`the
`data in the datasets to data contained in the card, which

`
`the data-containing
`may be contained in one or more of
`structures of the card, as shown in box 44.
`Preferably,
`the comparison data is contained in at
`least two of the
`data-containing structures of
`the card,
`to allow for an
`additional comparison to be made between the data sets.
`If
`the compared user
`input and the data do not match,
`the
`transaction is refused, as shown in box 46.
`The means for accessing the data preferably further
`includes
`a means
`for obtaining confirmation of user
`physically identifying data. The means may be a digital
`camera for taking a digital
`image,
`a camera for taking a
`photographic image,
`a means for reading a fingerprint, or
`any other means by which a machine can collect unique
`physical
`or biometric data
`from the user.
`In the
`illustrative embodiment, once the user input information is
`found to match
`the data
`contained in the
`financial
`transaction card,
`the means
`for accessing the data then
`collects confirmatory physical data from the user,
`as
`depicted in box 48. The confirmatory user data is compared
`to standards contained in the encrypted datasets on the
`financial
`transaction card,
`as
`depicted in box
`50.
`Preferably,
`the standards are contained in more than one
`data-containing structure of
`the card,
`to allow for the
`standards to be compared to one another, further increasing
`security.
`The comparison of
`the collected confirmatory
`data may be done by the means for accessing the data, or
`the collected data may be
`transmitted,
`along with the
`Standards to the receiving computer system, which may then
`make the comparison.
`If the confirmatory data matches the
`Standards contained in the encrypted data sets,
`then the
`transaction is authorized, as shown in box 54, otherwise
`the transaction is denied, as depicted in box 56.
`As used herein the term “data-containing structure” is
`intended to encompass
`any
`type
`of machine
`readable
`optically stored information such as executable programming
