## Background
FIELD OF TECHNOLOGY
Aspects of the invention relate to components for constructing a purchasing instrument that includes enhanced electronic features.
BACKGROUND
A traveler anticipating a visit to a particular country may obtain a purchasing instrument, such as traveler's checks in a desired currency. Traveler's checks may insulate travelers from fluctuating foreign exchange rates. Like cash, traveler's checks may include static anti-counterfeiting properties. Such anti-counterfeiting properties may include special paper or embedded designs. However, such static anti-counterfeiting properties are at risk of being identified, copied and/or otherwise duplicated.
Traveler's checks are also typically limited to a currency and denomination printed on a face of the document. Accordingly, a traveler's spending is limited by the amount and currency on his or her traveler's checks.
A traveler may also utilize credit cards or other purchasing instruments in lieu of traveler's checks. However, use of such a purchasing instrument is also associated with risks.
Typically, sensitive data associated with a credit card, or other purchasing instrument, is printed on a face (front or back) of the card. The sensitive data may include a unique card number, a card holder's name, an expiration date of the credit card number, an amount, a currency, a card verification value (“CVV”) or any other suitable sensitive data.
The sensitive data may be visible to an onlooker who may obtain a copy (e.g., by taking a picture) of the sensitive data. The copied sensitive data may be used to initiate fraudulent transactions.
Typically, credit cards also include sensitive data encoded on a magnetic stripe. The sensitive data encoded on the magnetic stripe is read when the card is “swiped” through a card reader. Thieves may utilize a skimming device to obtain a copy of the sensitive data encoded on the magnetic stripe. For example, a thief may utilize a skimming device placed on or in an automated teller machine (“ATM”). The skimmer may be placed over a card slot reader of the ATM and may read the magnetic stripe as the card is inserted into the slot.
A traveler may not notice that a skimmer has been placed on or in an ATM because the skimmer may not impede access to the ATM or card reader. Thus, the skimmer may obtain a copy of the sensitive data encoded on a credit card's magnetic stripe in a manner transparent to the traveler.
Technology is currently being developed that may reduce a risk of a thief obtaining a copy of sensitive credit card data. For example, some credit cards are now produced with “EMV” chips. EMV is a technology that derives its name from the companies (Europay, MasterCard, and Visa) that helped develop the technology. When the credit card and its associated EMV chip are inserted into a specialized card reader, the reader powers the EMV chip and the EMV chip generates a new authorization code each time the credit card is used. Thus, simply copying the sensitive data printed on the face of the credit card or encoded on the magnetic stripe may be insufficient to initiate a fraudulent transaction.
In addition to technology specifically developed to combat fraud, it would be desirable to leverage other technology to design a purchasing instrument that is more protective of sensitive data associated with the purchasing instrument.
However, the relevant form factor associated with purchasing instruments is limited. Purchasing instruments are typically 85.60 millimeters (“mm”)×53.98 mm×0.8 mm. This limited form factor allows purchasing instruments to fit into a traveler's wallet or pocket. Yet, this form factor also presents design challenges. For example, one design challenge involves the difficulty of attempting to include electronic features within the limited form factor. For example, to maintain this limited form factor, a purchasing instrument cannot be constructed using a relatively large power supply.
Furthermore, travelers typically expect to be able to fold or bend purchasing instruments. For example, a traveler may expect to fold a traveler's check and store the check in a wallet or pocket.
In would be desirable to provide a purchasing instrument that more securely protect sensitive data.
In would be desirable to provide a purchasing instrument that incorporates electronic features that allow for efficient use and functionality of such purchasing instruments.
It would be desirable to provide a purchasing instrument that includes electronic features and allows travelers to fold or bend the purchasing instrument.
Accordingly, it would be desirable to provide systems and methods for an OLED-Based Travel Card.

DETAILED DESCRIPTION
Aspects of the invention relate to a credit-card-size device (hereinafter, “smart card” or “smart check”) that leverages organic light emitting diode (“OLED”) technology to enhance security of sensitive data associated with a traveler's check or other purchasing instruments.
Aspects of the invention also relate to a smart card or smart check that leverages organic light emitting diode (“OLED”) technology to enhance functionality and usability of a purchasing instrument.
OLEDs are typically solid-state semiconductors constructed from a thin film of organic material. OLEDs emit light when electricity is applied across the thin film of organic material. Because OLEDs are constructed using organic materials, OLEDs may be safely disposed without excessive harm to the environment.
OLEDs may also be used to construct a display that is flexible. OLED displays may be folded, bent or rolled. An exemplary smart check as described herein may be passed through a check reader that typically bends a paper check when reading the check. The OLED display may be configured to present information on a face of the smart check such that the smart check presents information that is formatted and positioned on the face of the smart check as expected by check readers that typically read paper checks.
Furthermore, OLEDs may be used to construct a display that consumes less power compared to other display technologies. For example, in a Liquid Crystal Display (hereinafter, “LCD”) power must be supplied to the entire backlight to illuminate just one pixel in the display. In contrast, an OLED display does not necessarily include a backlight. Furthermore, in an OLED display, preferably, only the illuminated pixel draws power.
Therefore, power efficiency of OLED technology presents a possibility for designing electronic purchasing instruments (hereinafter, “smart checks”) that provide enhanced security and functionality.
As used herein, a smart check may function as any suitable purchasing instrument. Suitable purchasing instruments may include a credit card, check, traveler's checks, debit card and any suitable purchasing device. Suitable purchasing instruments may include purchasing instruments that conform to specifications published by the International Organization for Standardization. Illustrative specifications may include: ISO/IEC 7810, ISO/IEC 7811 and ISO/IEC 7816, which are hereby incorporated herein by reference in their respective entireties.
The smart check may not present any sensitive data printed or embossed on a face of the smart check. Rather, sensitive data may be electronically stored within the smart check. The sensitive data stored within the smart check may only be visible when presented on an OLED display of the smart check. The smart check may store sensitive data associated with two or more purchasing instruments. The smart check may be configured to periodically display sensitive data in response to pre-determined conditions.
Sensitive data stored on the smart check may be altered. For example, a traveler or smart check user (collectively, “user”) may add sensitive data and thereby store a new purchasing instrument on the smart check. A representation of the new purchasing instruments or currency value stored within the smart check may be presented to a user using an OLED display.
As further example, sensitive data may include a currency value. The currency value may be dynamically altered based on a geographic location of the smart check or a change in foreign currency exchange rates. A value stored on the smart check may be increased or decreased based on a geographic location of the smart check. In a certain location, specific purchasing instruments stored on the smart check may be disabled.
In some embodiments, a currency value stored on the smart check may be associated with a default currency or a default country. A default currency/country may be specified by a user. For example, The default currency/country may be selected by the user at a time the value is stored on the smart check.
A default currency/country may be determined based a residence of a user. The default currency/country may be associated with any country or currency. For example, a default currency may include an electronic currency that is unaffiliated with a particular country.
The user may attempt to use the smart check in a country or as a currency that is different from the default currency/country. A currency and amount of the currency activated and/or presented on the smart check may be determined based on a currency exchange rate for converting the default currency value into any desired currency. For example, a default currency value may be automatically converted into a currency of a country where the smart check is being used. The smart check may identify a location or currency when inserted into a POS terminal and/or when communicating with a network access point.
The OLED display may be touch-sensitive. The user may select a purchasing instrument stored on the smart check by touching a displayed representation corresponding to a desired purchasing instrument. Some embodiments may include an OLED display on front and back faces of the smart check. Some embodiments may include an OLED display on a thickness of the smart check. The OLED display may enable video playback capability.
In response to a user selection, or in response to certain pre-determined conditions, sensitive data stored on the smart check may be deleted. For example, sensitive data may be deleted in response to expiration of a purchasing instrument. Sensitive data may be deleted in response to detecting a potential security breach. In some embodiments, sensitive data may be deleted when a smart check associated with a security breach is used at a merchant point-of-sale (“POS”) terminal.
Waiting for the smart check to be used at the POS terminal may allow a potential fraud and thief to be identified at the POS terminal. For example, an authorized user of the smart check may report to an entity that issued the smart check that the smart check has been lost or stolen. In response the user's report, a fraud flag may be associated with sensitive data of the smart check. In some embodiments, when the smart check connects to a network, the fraud flag may be pushed to and stored on the smart check.
In some embodiments, when the smart check is reported as lost or stolen, a decoy set of sensitive data may be pushed to the smart check. The decoy set of sensitive data may include executable code that reports to a central location each time the decoy set of sensitive data is copied, stored or any other suitable operation performed on the decoy set of sensitive data. For example, the executable code may transmit a time/date stamp and location of when and where the decoy set of sensitive data was copied.
The sensitive data previously stored on smart card reported by the authorized user as lost or stolen may be deleted. In some embodiments, the fraud flag may indicate that security of sensitive data stored on the smart check has been compromised.
When a smart check reported as lost or stolen is used at a POS terminal, the associated fraud flag may trigger a fraud detection process. The fraud detection process may include instructing the POS terminal to capture a biometric feature or a picture of a potentially unauthorized individual who presented the flagged smart check at the POS terminal. The fraud detection process may include denying a transaction or purchase initiated at the POS terminal using the flagged smart check or any other suitable fraud prevention measure. Waiting until the flagged smart check is used at a POS terminal may increase a possibility of identifying who compromised the security of the sensitive data, where/how the compromise occurred and who has attempted to use the comprised sensitive data.
The smart check may include one or more biometric sensors. Illustrative biometric sensors may include a fingerprint scanner, camera, microphone or any other suitable sensor for capturing a biometric feature. To authenticate a release of sensitive data, a user may present a biometric feature to the biometric sensor for verification. The smart check may only authorize release of the sensitive data after verifying a submitted biometric feature.
The smart check may enable more secure financial transactions. For example, online banking transactions may be made more secure by requiring entry of a valid biometric feature, such as a fingerprint, prior to authorizing a transaction or accessing an online banking portal. Embodiments may utilize a camera to verify a biometric feature or identity of a user prior to authorizing a transaction.
The smart check may be powered by a battery. The battery may be recharged when the smart check is inserted into an ATM or other card reader. A smart check may store currency in way that is portable, transferrable and more tangible than virtual currency. The smart check may utilize an OLED display to present an image of a denomination and currency. The currency displayed may be determined based on a location of the smart check.
For example, a cruise may include multiple stops at a plurality of countries. Each country may be associated with a different currency. At each stop, a value stored on the smart check and currency associated with the stored value may be automatically updated and displayed.
A location of the smart check may be detected based on an access point used by the smart check to access a network. In some embodiments, the smart check may include a GPS chip for receiving and/or transmitting GPS signals. In some embodiments, the smart check may include cellular telecommunication capabilities. A location of the smart check may be determined using cellular triangulation techniques. In some embodiment, the cellular telecommunication capabilities may only be used to determine a location of the smart check.
In some embodiments, an ATM or POS terminal may include a card reader that detects light, color or a pattern presented on an OLED display. A presented pattern may include a quick response (“QR”) code. In some embodiments, such light or color patterns may be used to present sensitive data to a card reader in a way that reduces a risk of exposure of the sensitive data.
Apparatus for a smart check are provided. The smart check may include an array of OLEDs. The OLEDs may form one or more pixels. The OLEDs may form a display of the smart check.

In some embodiments, pressure sensitive button 107 may include a portion 104 that dips below a surface of the smart check.
FIG. 2 shows structures 200 of an illustrative OLED layer, such as OLED layer 101 (shown in FIG. 1). Structures 200 include four layers: encapsulation layer 201, organic layer 203, circuitry layer 205 and substrate layer 207.
Encapsulation layer 201 protects the OLED layer from exposure to oxygen, water and other contaminants. Preferably, encapsulation layer 201 is flexible and transparent. Glass is an exemplary material that may be used to construct encapsulation layer 201. When glass is used to construct encapsulation layer 201, the glass may be very thin and flexible. For example, the glass may be between 50 micrometers (“μm”) and 100 μm thick.
In some embodiments, encapsulation layer 201 may be constructed using thin-film encapsulation techniques such as Atomic Layer Deposition (“ALD”). ALD is a process that utilizes chemicals that, when deposited on a material, react to create a solid, thin film.
Structures 200 include organic layer 203.
Organic layer 203 typically includes an emissive solid-state semiconductor. Organic layer 203 may be constructed from a thin film of organic (carbon-based) material. For example, organic layer 203 may include one or more OLEDs. When electricity is applied to an OLED within organic layer 203, electrons flow through organic layer 203 and release photons, thereby emitting light. Different types of emissive materials may be used. Each type of material may be associated with a different color light. An intensity of light emitted by organic layer 203 may be controlled by the amount of electricity flowing through organic layer 203.
Organic layer 203 may be doped with “host” materials. Host material may affect a property, such as power efficiency, of organic layer 203. For example, organic layer 203 may be doped with materials that improve its operation and/or achieve a desired color.
Organic layer 203 may include two or more sub-layers (not shown). For example, organic layer 203 may include 5, 10 or 15 sublayers. Illustrative sub-layers may include: (1) an electron transport layer, (2) a blocking layer, (3) an emissive layer, (4) a hole transport layer and (5) an injection layer.
For example, an emissive layer may be placed between a cathode and an anode. When electricity is applied, electrons flow from the cathode to the anode. OLED displays may be driven by electrical current or voltage. In a preferred embodiment, the OLED display is driven by current. The cathode inserts electrons into the emissive layer, and the anode removes the electrons. Electron “flow” through the emissive layer releases photons, generating light. The color of the generated light may be changed by including different types of materials within the emissive layer.
A direction of light emitted by organic layer 203 may be controlled by a degree of transparency of the anode and/or cathode. In some embodiments, a cathode may be reflective. Such a cathode may preferably be constructing using an aluminum based-compound or lithium fluoride. An anode may be transparent. A transparent anode may preferably be constructed using indium tin oxide. In such embodiments, when current flows between the cathode and anode, light is emitted through circuitry layer 205 and substrate layer 207. Circuitry layer 205 and substrate layer 207 may be transparent. Such embodiments may be referred to as “bottom-emitting OLEDs.”
In some embodiments, the cathode may be transparent. Such a cathode may preferably be constructed using indium tin oxide. The anode may be reflective. The reflective anode may direct light toward the transparent cathode. Such embodiments may be referred to as “top-emitting OLEDs.” Typically, top-emitting designs are more efficient and are used to construct higher resolution OLED displays.
Additionally, top-emitting designs may allow organic layer 203 to be formed on a non-transparent substrate. Small- and medium-sized OLED displays (e.g., 1-7 inches) are typically constructed using top-emitting techniques.
Organic layer 203 may include one or more pixels. Different architectures are available for forming pixels using OLEDs. One exemplary architecture includes positioning different color (e.g., red, green and blue) OLEDs adjacent to each other. Another exemplary architecture includes stacking different color OLEDs on top of each other. OLEDs may be stacked because materials used to construct organic layer 203 may be transparent. A stacked design may provide a smaller pixel size and higher resolution.
Structures 200 include circuitry layer 205. Circuitry layer 205 includes electronics that drive one or more pixels formed within organic layer 203. Preferably, amorphous silicon (“a-Si”) and low temperature polysilicon (“LTPS”) may be used to construct circuitry layer 205. In some embodiments, circuitry layer 205 may be transparent.
Substrate layer 207 supports circuitry layer 205, organic layer 203 and encapsulation layer 201. Substrate layer 201 may be constructed using various materials. For example, substrate layer 207 may be constructed using glass, plastic or metal materials. In some embodiments, such as in bottom-emitting OLEDs, substrate layer 207 may function as encapsulation layer 201.
