Definitions
- the present disclosure relates to a credit card configured to include a power source for a variety of applications and, more particularly, a credit card configured to include an accelerometer, such as a piezoelectric accelerometer, as a power source to enhance security and facilitate payment functions.
- an accelerometer such as a piezoelectric accelerometer
- a credit card may be configured to employ an integrated energy source (e.g., an accelerometer), within the card in order to provide power for sophisticated physical security components.
- the accelerometer may be a piezoelectric accelerometer.
- motion of the card such as carrying the card while walking, raising the card, or moving the card around or pressure on the card or on an area of the accelerometer in particular allows generation of electrical energy to power a sensor or other physical security features of the card.
- Incorporation of a user input or biometric sensor with the integrated energy source may allow the card to be “unlocked” temporarily (e.g., for a specified time period such as 15 seconds).
- the integrated power source might power input of a user ID (e.g., pin code, motion pattern) or a biometric sensor allowing the card to be unlocked so that it only works temporarily.
- the card may be unlocked for a specified time period while the card is energized and after the user ID or biometric has been input.
- An integrated energy source such as a piezoelectric accelerometer may eliminate the need for an on-board battery and allow a card to work without requiring power from the point-of-sale device. These measures would increase security by allowing a card to work only while it is energized and unlocked by a user while increasing the range of use to more mobile applications that might involve payment without a traditional point of sale device.
- a card configured as described would allow for on-card token generation as well as on-card displays of information as well as on-card generation of dynamic authorization data without requiring an on-card battery.
- a payment device may include an integrated power source including a piezoelectric accelerometer, a processor in communication with the integrated power source, and a memory in communication with the processor, the memory storing instructions that are executable by the processor; and an input/output circuit in communication with the processor.
- Kinetic energy and/or pressure translated to the payment device and, thus, to the piezoelectric material may generate electrical energy to power the processor, memory, and input/output circuit.
- FIGS. 1 a , 1 b , and 1 c illustrate various views of an embodiment of a payment device including an integrated energy source
- FIG. 2 is a view of a sample circuit design of the payment device with an integrated power source and various input devices.
- FIGS. 1 a , 1 b , and 1 c generally illustrate a payment device 100 .
- FIG. 1 a illustrates a front outer view of the payment device 100
- FIG. 1 b illustrates a view of an inner layer of the payment device 100
- FIG. 1 c illustrates a back outer view of payment device 100 .
- the payment device 100 may take on a variety of shapes and forms.
- the payment device 100 is a traditional card such as a debit card or credit card.
- the card may be a fob on a key chain.

- the actuation means 124 may include any structure to facilitate motion of the mass 120 within the piezoelectric accelerometer. The motion of the mass 120 within the body 119 or pressure exerted by a user will exert a physical force on the piezoelectric material 122 as either bending or compressing the material 122 .
- Compression force on the material 122 includes a force exerted to one side of the piezoelectric material 122 while the opposing side rests against a fixed surface, for example, and inner wall of the power source 114 . Bending force may involve the mass 120 or other means exerting a force on the piezoelectric material 122 about an axis of the material 122 .
- the piezoelectric accelerometer includes a tri-axis accelerometer such as the KX112 or KXCJB as produced by Kionix, Inc., of Ithaca, N.Y. Of course, other types of piezoelectric accelerometers may be suitable for the power generation and other functions described herein.

Some embodiments of the piezoelectric accelerometer power source 114 may include barium titanate, lead-zirconate, lead-titanate, lead metaniobate, and other piezoelectric materials 122 .
- the payment device 100 In use, motion of the payment device 100 to actuate the mass 120 against the piezoelectric material 122 or pressure by a user compressing a piezoelectric material of the card generates electrical energy.
- the energy created by the power source 114 may then be consumed by the processor 118 , display 116 , or other components of the payment device 100 . Too, the energy may be stored for later use in a power storage element 127 .
- the power storage element is a rechargeable battery, capacitor, or other element capable of frequently receiving and storing electrical energy.
- the payment device 100 may also include circuitry or other means to transfer the generated energy from the power source 114 and/or the power storage element 127 to the processor 108 , the display, or other components of the payment device 100 .
- the substantially flat front surface 102 may include a translucent region 126 through which the display 116 may be viewed.
- a user may want to view the display 116 .
- the display may have to be protected from the elements.
- a translucent region of either the top 102 layer and/or bottom layer 104 may be placed over the display 105 .
- there may be a plurality of displays 105 there may need to be room in the inner layer for each display and there may need to be translucent regions in the top and/or bottom layer to see the displays.
- Embodiments including the display 116 are further described by U.S.
- the payment device 100 may also have a stiffness layer 128 .
- Many circuits, processors, memories, displays, etc., may not be adapted to bend. In fact, many electronic devices break when the devices 100 are bent beyond a threshold.
- a stiffening layer 128 of non-flexible material may be added to the payment device 100 .
- the stiffening layer 128 may be part of the front layer 102 , back layer 104 , inner layer 106 or the entire payment device 100 may be made of a stiff material.
- the payment device may have a variety of components that make up the payment device 100 .
- a processor 200 may be physically configured to enable the input 118 and display 116 along with the other computing elements.
- the processor 200 may be any processor that fits in the allotted space and can operate using the limited power in the payment device 100 and not generate excessive heat.
- the processor 200 may be adapted to turn off sections of the processor 200 when those sections are not needed. For example, the processor may turn off the display functions until an input is received from the input device 118 to save power from the power source 114 .
- the memory 202 may be any appropriate memory that fits in the space and can operate in the power environment of the payment device 100 .
- the memory 202 may be physically configured to store steps or instructions that are executable by the processor 200 to enable the input device 118 and the display 116 and other functions as herein described.
- the memory 202 may be RAM or ROM, may be transitory or may be persistent depending on the needs of the specific embodiment of the payment device 100 .
- the memory 202 may be physically part of or separate from the processor 200 .
- the input/output circuit 112 may communicate signals to and from the processor 200 and it also may be part of the processor 200 or may be a separate device. In addition, the input/output circuit 112 may be required to fit in the space of the payment device 100 and may be required to operate in the power environment of the payment device 100 .
- Maintaining sufficient power in the power source 114 may be a concern as the display 116 , input device 118 , or other components of the device 100 may not operate if there is not enough power.
- a low power warning may be communicated.
- the low power warning may be a message on the display 116 , an email or a text message to a preset address, or an activated light indicator (e.g., an LED) on the device.
- communicating the low power message may also use power so the low power warning may only be communicated if the payment device 100 receives an acceptable communication signal above a threshold such that the message may be quickly communicated without requiring excessive re-sends or repeats.
- the message may be communicated via a transceiver 204 using, for example, Wi-Fi signals, cellular signals, near field communication systems or infrared signals.
- a user may “charge” the payment device 100 by moving or shaking the device until a sufficient charge is present to activate payment device functions. Since most users carry the payment device on their person, it is envisioned that typical daily movement such as walking, etc., will keep sufficient charge on the device 100 .
- the device may be charged or enter a powered or “wake up” state upon the natural motion of raising the card from a wallet or pocket during a payment transaction. Natural motions may be combined with other actions such as compressing a portion of the card, touching a heat sensor of the card, tapping the card against a surface, etc., to charge and/or wake up the payment device.
- the input device 118 may also take on a variety of forms and be actuated in a variety of ways. Logically, the input device 118 may have to fit with the payment device 100 and may be in communication with the input/output circuit 112 . In one embodiment, the input device 118 is a heat sensitive region on the payment device 100 and it may be actuated by warming the heat sensitive region. In another embodiment, the input device 118 is a touch sensitive region on the payment device 100 that is actuated by touching the touch sensitive region. In some embodiments, the input device 118 may be visible and in other embodiments, the input device 118 may be under a logo, such as from the payment device 100 issuer.
- input device 118 may be a motion sensor or coupled to a motion sensor such as the piezoelectric accelerometer of the integrated power source 114 .
- Such an input device 118 may be actuated by flicking or clicking the payment device 100 which may cause a reading from the motion sensor to be beyond a threshold (e.g., a voltage generated by the piezoelectric accelerometer integrated power source 114 ).
- the threshold may be adjusted by a user as some user may be more active than other users.
- a unique, user-defined pattern of taps with the device 100 against a surface may activate the device 100 for a period of time.
- the integrated power source 114 piezoelectric accelerometer may register each tap and the processor 108 may execute instructions to verify the pattern to activate the payment device 100 .
- a movement pattern of the device 100 may also cause activation.
- the input device 118 may be an electronic signal and the input device 118 may be actuated by receiving an actuation signal from a trusted device.
- the trusted device may be a portable computing device like a mobile phone, may be a payment device reader or an RFID device.
- a user may communicate a signal from a mobile telephone to the transceiver 204 in the payment device 100 which may be received by the input device 118 and act as the input to actuate the display 118 or activate the payment device 100 itself such that payments may be made using the device 100 .
- the device activation may only persist for a short period of time (e.g., 15 seconds) such that a user may cause a payment to be processed using the device 100 and then the device may become locked or otherwise disabled until needed again.
- the message may be encrypted and may require an exchange of electronic keys to establish trust between the payment device 100 and the trusted computing device.
- the actuation signal if the actuation signal is received from a non-trusted device more than a threshold number of times during a period, the device may become locked for an extended time or deactivated completely via a signal to the device 100 via the transceiver. By using an electronic signal as the input, the security of the payment device 100 may be increased.
- the input device 118 may be a biometric sensor adapted to detect human body characteristics of the user, such as fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements, for authentication purposes.
- the input device 118 may be actuated by receiving a trusted fingerprint on the fingerprint reader.
- the memory 202 may include instructions that are executed by the processor 200 which verify the trusted fingerprint as received at the input device 118 .
- the security of the payment device 100 may be increased.
- the input device 118 may be an image sensor.
- the input device 118 may be actuated by receiving an acceptable image which may be set up in advance by an approved user.
- the memory 202 may include instructions that are executed by the processor 200 to verify the image and transmit an approval signal. By using an image sensor, the security of the payment device 100 may be increased.
- the input device 118 may be a sound sensor such as a microphone.
- the input device 118 may be actuated by receiving an acceptable sound or voice which may be set up in advance by an approved user.
- a sound analysis module may be stored in the memory 202 and may include instructions that are executed by the processor 200 to receive sound and communicate an approval signal that may be received in response by the receiver 204 . By using a sound sensor, the security of the payment device 100 may be increased.
- the integrated power source 114 may facilitate many further security functions for the payment device 100 to restrict use of the device to authorized users.
- a user may activate the payment device 100 in a variety of ways that do not require power from a point-of-sale device such as a traditional credit card reader.
- motion of the payment device 100 may cause motion of the mass 120 within the piezoelectric accelerometer integrated power source 114 and cause it to deform (i.e., compress or bend) the piezoelectric material 122 .

Description
- The present disclosure relates to a credit card configured to include a power source for a variety of applications and, more particularly, a credit card configured to include an accelerometer, such as a piezoelectric accelerometer, as a power source to enhance security and facilitate payment functions.
- The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
- Credit card transactions have long been the target of criminal fraud. In a digital purchase transaction, a physical credit card is not used and, thus, stolen information alone may be used by the criminal to complete a fraudulent transaction. In a point-of-sale transaction using the physical card, criminals must employ sophisticated techniques to duplicate the physical card using stolen credit card holder information. Credit card companies have gone to great lengths to insure physical cards cannot be copied by incorporating security measures into each physical card. However, advances in small-scale production of these measures have made it increasingly easier for criminals to duplicate even advanced measures for physical credit card security.
- Too, there are numerous different measures credit card issuers might employ to deter or prevent physical credit card fraud. However, cost and size limitations make such measures impractical for a wallet-sized credit card. Increasingly, there is a need for smaller, more sophisticated measures to ensure physical credit card security.
- Features and advantages described in this summary and the following detailed description are not all-inclusive. Many additional features and advantages will be apparent to one of ordinary skill in the art in view of the drawings, specification, and claims hereof. Additionally, other embodiments may omit one or more (or all) of the features and advantages described in this summary.
- A credit card may be configured to employ an integrated energy source (e.g., an accelerometer), within the card in order to provide power for sophisticated physical security components. In some embodiments, the accelerometer may be a piezoelectric accelerometer. For example, motion of the card such as carrying the card while walking, raising the card, or moving the card around or pressure on the card or on an area of the accelerometer in particular allows generation of electrical energy to power a sensor or other physical security features of the card. Incorporation of a user input or biometric sensor with the integrated energy source may allow the card to be “unlocked” temporarily (e.g., for a specified time period such as 15 seconds). Additionally, the integrated power source might power input of a user ID (e.g., pin code, motion pattern) or a biometric sensor allowing the card to be unlocked so that it only works temporarily. In some embodiments, the card may be unlocked for a specified time period while the card is energized and after the user ID or biometric has been input. An integrated energy source such as a piezoelectric accelerometer may eliminate the need for an on-board battery and allow a card to work without requiring power from the point-of-sale device. These measures would increase security by allowing a card to work only while it is energized and unlocked by a user while increasing the range of use to more mobile applications that might involve payment without a traditional point of sale device. Still further, a card configured as described would allow for on-card token generation as well as on-card displays of information as well as on-card generation of dynamic authorization data without requiring an on-card battery.
- In one embodiment, a payment device may include an integrated power source including a piezoelectric accelerometer, a processor in communication with the integrated power source, and a memory in communication with the processor, the memory storing instructions that are executable by the processor; and an input/output circuit in communication with the processor. Kinetic energy and/or pressure translated to the payment device and, thus, to the piezoelectric material may generate electrical energy to power the processor, memory, and input/output circuit.
-
FIGS. 1a, 1b, and 1c illustrate various views of an embodiment of a payment device including an integrated energy source; and -
FIG. 2 is a view of a sample circuit design of the payment device with an integrated power source and various input devices. - The figures depict a preferred embodiment for purposes of illustration only. One skilled in the art may readily recognize from the following discussion that alternative embodiments of the structures and methods illustrated herein may be employed without departing from the principles described herein.
-
FIGS. 1a , 1 b, and 1 c generally illustrate apayment device 100. In particular,FIG. 1a illustrates a front outer view of thepayment device 100,FIG. 1b illustrates a view of an inner layer of thepayment device 100, andFIG. 1c illustrates a back outer view ofpayment device 100. Thepayment device 100 may take on a variety of shapes and forms. In some embodiments, thepayment device 100 is a traditional card such as a debit card or credit card. In other embodiments, the card may be a fob on a key chain. As long as thepayment device 100 may be able to communicate securely with a payment accepting device, the form of the payment device may not be especially critical and may be a design choice. For example, manylegacy payment devices 100 may have to be read by a magnetic stripe reader and thus, thepayment device 100 may have to be sized to fit through a magnetic card reader. In other examples, thepayment device 100 may communicate through near field communication and the form of thepayment device 100 may be virtually any form. Of course, other forms may be possible based on the use of the card, the type of reader being used, etc. - Physically, the
payment device 100 may be a card and the card may have a plurality of layers to contain the various elements that make up thepayment device 100 as illustrated inFIGS. 1a, 1b, and 1c . In one embodiment, thepayment device 100 may have a substantiallyflat front surface 102 and a substantiallyflat back surface 104 opposite the front surface. Logically, in some embodiments, thefaces inner layer 106 may have openings for aprocessor 108,memory 110, input/output circuit 112, andpower source 114. Some embodiments may also include adisplay 116 andinput device 118 that may be part of thepayment device 100. In some embodiments, theinput device 118 may include a biometric sensor. - The
power source 114 may include transducer such as, for example, a piezoelectric accelerometer including ahousing body 119, amass element 120, apiezoelectric material 122, an actuation means 124, and anenergy storage device 126. The actuation means 124 may include any structure to facilitate motion of themass 120 within the piezoelectric accelerometer. The motion of themass 120 within thebody 119 or pressure exerted by a user will exert a physical force on thepiezoelectric material 122 as either bending or compressing thematerial 122. Compression force on thematerial 122 includes a force exerted to one side of thepiezoelectric material 122 while the opposing side rests against a fixed surface, for example, and inner wall of thepower source 114. Bending force may involve themass 120 or other means exerting a force on thepiezoelectric material 122 about an axis of thematerial 122. In some embodiments, the piezoelectric accelerometer includes a tri-axis accelerometer such as the KX112 or KXCJB as produced by Kionix, Inc., of Ithaca, N.Y. Of course, other types of piezoelectric accelerometers may be suitable for the power generation and other functions described herein. - The
material 122 may include crystal and ceramic materials. Some embodiments may employ a single-crystal material 122 (e.g., quartz) while other embodiments may employ ceramic materials. Some embodiments of the piezoelectricaccelerometer power source 114 may include barium titanate, lead-zirconate, lead-titanate, lead metaniobate, and otherpiezoelectric materials 122. - In use, motion of the
payment device 100 to actuate themass 120 against thepiezoelectric material 122 or pressure by a user compressing a piezoelectric material of the card generates electrical energy. The energy created by thepower source 114 may then be consumed by theprocessor 118,display 116, or other components of thepayment device 100. Too, the energy may be stored for later use in apower storage element 127. In some embodiments, the power storage element is a rechargeable battery, capacitor, or other element capable of frequently receiving and storing electrical energy. Of course, thepayment device 100 may also include circuitry or other means to transfer the generated energy from thepower source 114 and/or thepower storage element 127 to theprocessor 108, the display, or other components of thepayment device 100. - In embodiments including a
display 116, the substantially flatfront surface 102 may include atranslucent region 126 through which thedisplay 116 may be viewed. Logically, a user may want to view thedisplay 116. At the same time, the display may have to be protected from the elements. Thus a translucent region of either the top 102 layer and/orbottom layer 104 may be placed over the display 105. It also should be noted that there may be a plurality of displays 105, there may need to be room in the inner layer for each display and there may need to be translucent regions in the top and/or bottom layer to see the displays. Embodiments including thedisplay 116 are further described by U.S. patent application Ser. No. 14/587,310 entitled “SELECTABLE DISPLAY OF DATA ON A PAYMENT DEVICE” the entire disclosure of which is entirely incorporated by reference herein. - The
payment device 100 may also have astiffness layer 128. Many circuits, processors, memories, displays, etc., may not be adapted to bend. In fact, many electronic devices break when thedevices 100 are bent beyond a threshold. Thus, astiffening layer 128 of non-flexible material may be added to thepayment device 100. Thestiffening layer 128 may be part of thefront layer 102, backlayer 104,inner layer 106 or theentire payment device 100 may be made of a stiff material. - Now referring to
FIG. 2 , the payment device may have a variety of components that make up thepayment device 100. Aprocessor 200 may be physically configured to enable theinput 118 anddisplay 116 along with the other computing elements. Theprocessor 200 may be any processor that fits in the allotted space and can operate using the limited power in thepayment device 100 and not generate excessive heat. Theprocessor 200 may be adapted to turn off sections of theprocessor 200 when those sections are not needed. For example, the processor may turn off the display functions until an input is received from theinput device 118 to save power from thepower source 114. - The
memory 202 may be any appropriate memory that fits in the space and can operate in the power environment of thepayment device 100. Thememory 202 may be physically configured to store steps or instructions that are executable by theprocessor 200 to enable theinput device 118 and thedisplay 116 and other functions as herein described. Thememory 202 may be RAM or ROM, may be transitory or may be persistent depending on the needs of the specific embodiment of thepayment device 100. Thememory 202 may be physically part of or separate from theprocessor 200. - Similarly, the input/
output circuit 112 may communicate signals to and from theprocessor 200 and it also may be part of theprocessor 200 or may be a separate device. In addition, the input/output circuit 112 may be required to fit in the space of thepayment device 100 and may be required to operate in the power environment of thepayment device 100. - Maintaining sufficient power in the
power source 114 may be a concern as thedisplay 116,input device 118, or other components of thedevice 100 may not operate if there is not enough power. In some embodiments, when power in thepower source 114 orpower storage element 127 falls below a threshold, a low power warning may be communicated. In some embodiments, the low power warning may be a message on thedisplay 116, an email or a text message to a preset address, or an activated light indicator (e.g., an LED) on the device. Of course, communicating the low power message may also use power so the low power warning may only be communicated if thepayment device 100 receives an acceptable communication signal above a threshold such that the message may be quickly communicated without requiring excessive re-sends or repeats. The message may be communicated via atransceiver 204 using, for example, Wi-Fi signals, cellular signals, near field communication systems or infrared signals. In embodiments using the piezoelectric accelerometer as the integratedpower source 114, a user may “charge” thepayment device 100 by moving or shaking the device until a sufficient charge is present to activate payment device functions. Since most users carry the payment device on their person, it is envisioned that typical daily movement such as walking, etc., will keep sufficient charge on thedevice 100. Too, the device may be charged or enter a powered or “wake up” state upon the natural motion of raising the card from a wallet or pocket during a payment transaction. Natural motions may be combined with other actions such as compressing a portion of the card, touching a heat sensor of the card, tapping the card against a surface, etc., to charge and/or wake up the payment device. - The
input device 118 may also take on a variety of forms and be actuated in a variety of ways. Logically, theinput device 118 may have to fit with thepayment device 100 and may be in communication with the input/output circuit 112. In one embodiment, theinput device 118 is a heat sensitive region on thepayment device 100 and it may be actuated by warming the heat sensitive region. In another embodiment, theinput device 118 is a touch sensitive region on thepayment device 100 that is actuated by touching the touch sensitive region. In some embodiments, theinput device 118 may be visible and in other embodiments, theinput device 118 may be under a logo, such as from thepayment device 100 issuer. - In another embodiment,
input device 118 may be a motion sensor or coupled to a motion sensor such as the piezoelectric accelerometer of the integratedpower source 114. Such aninput device 118 may be actuated by flicking or clicking thepayment device 100 which may cause a reading from the motion sensor to be beyond a threshold (e.g., a voltage generated by the piezoelectric accelerometer integrated power source 114). The threshold may be adjusted by a user as some user may be more active than other users. In some embodiments, a unique, user-defined pattern of taps with thedevice 100 against a surface may activate thedevice 100 for a period of time. For example, the integratedpower source 114 piezoelectric accelerometer may register each tap and theprocessor 108 may execute instructions to verify the pattern to activate thepayment device 100. Similarly, a movement pattern of thedevice 100 may also cause activation. - In yet another embodiment, the
input device 118 may be an electronic signal and theinput device 118 may be actuated by receiving an actuation signal from a trusted device. For example, the trusted device may be a portable computing device like a mobile phone, may be a payment device reader or an RFID device. In one embodiment, a user may communicate a signal from a mobile telephone to thetransceiver 204 in thepayment device 100 which may be received by theinput device 118 and act as the input to actuate thedisplay 118 or activate thepayment device 100 itself such that payments may be made using thedevice 100. In some embodiments, the device activation may only persist for a short period of time (e.g., 15 seconds) such that a user may cause a payment to be processed using thedevice 100 and then the device may become locked or otherwise disabled until needed again. Logically, the message may be encrypted and may require an exchange of electronic keys to establish trust between thepayment device 100 and the trusted computing device. In some embodiments, if the actuation signal is received from a non-trusted device more than a threshold number of times during a period, the device may become locked for an extended time or deactivated completely via a signal to thedevice 100 via the transceiver. By using an electronic signal as the input, the security of thepayment device 100 may be increased. - In some embodiments, the
input device 118 may be a biometric sensor adapted to detect human body characteristics of the user, such as fingerprints, eye retinas and irises, voice patterns, facial patterns, and hand measurements, for authentication purposes. For example, theinput device 118 may be actuated by receiving a trusted fingerprint on the fingerprint reader. Thememory 202 may include instructions that are executed by theprocessor 200 which verify the trusted fingerprint as received at theinput device 118. By using a biometric sensor for theinput device 118, the security of thepayment device 100 may be increased. - In yet another embodiment, the
input device 118 may be an image sensor. Theinput device 118 may be actuated by receiving an acceptable image which may be set up in advance by an approved user. Thememory 202 may include instructions that are executed by theprocessor 200 to verify the image and transmit an approval signal. By using an image sensor, the security of thepayment device 100 may be increased. - In other embodiments, the
input device 118 may be a sound sensor such as a microphone. Theinput device 118 may be actuated by receiving an acceptable sound or voice which may be set up in advance by an approved user. A sound analysis module may be stored in thememory 202 and may include instructions that are executed by theprocessor 200 to receive sound and communicate an approval signal that may be received in response by thereceiver 204. By using a sound sensor, the security of thepayment device 100 may be increased. - The integrated
power source 114 may facilitate many further security functions for thepayment device 100 to restrict use of the device to authorized users. In use, a user may activate thepayment device 100 in a variety of ways that do not require power from a point-of-sale device such as a traditional credit card reader. For example, motion of thepayment device 100 may cause motion of themass 120 within the piezoelectric accelerometer integratedpower source 114 and cause it to deform (i.e., compress or bend) thepiezoelectric material 122. Thus, any single motion or combination of various motions of the card may generate power that may be stored in thepower storage element 127, used by theprocessor 108, used by thedisplay 116, used by theinput device 118, etc. Such motion may cause the card to be “unlocked” or authorized to transmit a signal to facilitate completing a payment using thepayment device 100. For example, in some embodiments, a user may remove thepayment device 100 from his or her wallet and flick or shake the card causing the piezoelectricintegrated power source 114 to generate power which then causes theprocessor 108 to execute one or more instructions stored in thememory 110 to activate thedisplay 116,input device 118, or other aspect of the payment device as herein described to facilitate a payment transaction using the payment device. In other embodiments, thepayment device 100 may be activated using a plurality of different motions or a combination “passcode” motion. A user may configure thepayment device 100 to activate upon a series of motions. Upon moving the card in the configured sequence of motions, the card may activate. For example, the piezoelectric accelerometer integratedpower source 114 may detect various motions in one or more directional axes and one or more instructions stored in thememory 110 may be executed by theprocessor 108 to record a signature of the motions in thememory 110. The signature may be an amount of power or voltage produced by the piezoelectric accelerometer integrated power source 114 (e.g., the voltage exactly or substantially meeting or exceeding a threshold), an orientation of thepower source 114, or any other measurable and repeatable metric that a user may cause a piezoelectric accelerometer to produce and may be recorded, as known in the art. In use, the user may set a passcode motion sequence of moving the card in a circular motion, back and forth vertically once, then back and forth horizontally twice. Upon executing that same sequence of motions, thedevice 100 may be temporarily activated to facilitate completing a payment transaction. - Of course, many other single movements or combinations of movements are possible and may be used as the passcode motion sequence. In some embodiments, activation of the
payment device 100 may be caused by motion of themass 120 within the piezoelectric accelerometer integratedpower source 114 to deform thepiezoelectric material 122 and generate a voltage coupled with another input to theinput device 118. For example, thedevice 100 may be activated to facilitate a payment by the combination of a movement which translates to the piezoelectric accelerometer integratedpower source 114 and input from the input device. A user may remove thedevice 100 from his or her wallet with his or her thumb or other digit placed on theinput device 118. The combined motion of themass element 120 within the piezoelectric accelerometer integratedpower source 114 and pressure on theinput device 118 may cause theprocessor 108 to execute one or more instructions from thememory 110 to activate thedevice 100 and facilitate the payment transaction. Where theinput device 118 is a biometric sensor, thedevice 118 may read a biometric input (e.g., finger print or other biometric as known in the art and described herein) at thedevice 118 and use that as input for the combination of motions to activate thepayment device 100. - Other security and ease-of-use functions that may be facilitated by an integrated
power source 114 such as a piezoelectric accelerometer may include allowing thedevice 100 to facilitate payment only when energized and unlocked by the user, increasing a range ofdevices 100 employing wireless communication elements (e.g., Bluetooth, RFID, Wi-Fi, etc.), and allowing for on-device generation of security tokens, displays, and dynamic authorization data without requiring an on-card battery. - If the
input device 110 is activated, a variety of steps or events might happen. In one embodiment, a portion of thepayment device 100 may illuminate such as a logo or theinput device 110 itself may illuminate. In addition, the display 105 may display the desired sensitive data 130 (FIG. 1a ) when theinput device 110 is actuated. Thesensitive data 130 may be virtually any data needed to complete a payment transaction such as ccv, expiration date, card number, user name, and issuer. - In some embodiments, actuating the
input device 118 may cause thesensitive data 130 to be displayed in a rotating manner through thedisplay 116. For example, a single input (e.g., motion of the mass within the body of the piezoelectric accelerometer integrated power source 114) may cause the account number to be displayed, an additional input (e.g., pressure or a biometric reading of the input device 118) may cause the expiration date to be displayed and yet another input (e.g., a pattern of motions, combinations of inputs, etc.) may cause the expiration to be displayed. - In yet some more embodiments, the
payment device 100 may include a plurality ofdisplays 116 placed in thepayment device 100. A single input may cause thesensitive data 130 to appear in any of thedisplays 116. In yet another embodiment, theinput device 118 may be actuated to display the desiredsensitive data 130 in a rotating manner through thedisplays 116. In other embodiments, thesensitive data 130 may be displayed randomly in thevarious displays 116. - Logically, the display of
sensitive data 130 on thedisplay 116 may only be for a given period of time. The integratedpower source 114 may have a limited life so it may be logical to limit the length of the display. Further, the limited length may make it more difficult for thesensitive data 130 to be stolen. In some embodiments, the length of time for adisplay 116 to display thesensitive data 130 may have a default value and may be further adjusted by a user. - In accordance with the provisions of the patent statutes and jurisprudence, exemplary configurations described above are considered to represent a preferred embodiment of the invention. However, it should be noted that the invention can be practiced otherwise than as specifically illustrated and described without departing from its spirit or scope.
