## Title
Modular device payment system

## Abstract

A modular device payment module includes a chassis. A modular device connector is located on the chassis. A payment module database in the chassis stores funding source information and security information. A payment module engine in the chassis determines that the modular device connector has been connected to a modular device frame of a modular device, and retrieves modular device identifying information from the modular device. The payment module then determines that the modular device identifying information matches an authorized modular device identified by the security information in the payment module database and, in response, enables the transmission of at least some of the funding source information from the payment module database to conduct a payment transaction.

## Background
BACKGROUND
1. Field of the Disclosure
The present disclosure generally relates to online and/or mobile payments and more particularly to a modular device payment system.
2. Related Art
More and more consumers are purchasing items and services over electronic networks such as, for example, the Internet. Consumers routinely purchase products and services from merchants and individuals alike. The transactions may take place directly between a conventional or on-line merchant or retailer and the consumer, and payment is typically made by entering credit card or other financial information. Transactions may also take place with the aid of an on-line or mobile payment service provider such as, for example, PayPal, Inc. of San Jose, Calif. Such payment service providers can make transactions easier and safer for the parties involved. Purchasing with the assistance of a payment service provider from the convenience of virtually anywhere using a mobile device is one main reason why on-line and mobile purchases are growing very quickly.
The use of phones and other user devices for making online and/or mobile payments is growing rapidly, as traditional payment devices such as cash and credit cards are being replaced by wireless payment systems that allow the user to use their phone or other user device to transmit payment information to a merchant device of a merchant in order to complete a purchase.
Traditionally, phones have been provided by manufacturers to users as an integrated device that must be entirely replaced when one or more components fail or become obsolete. However, recently the concept of a modular phone has been proposed, which provides a modular phone frame to which different modular components of the phone may be attached (e.g., a screen module, a battery module, a storage module, a camera module, a speaker module, etc.) The use of modular components, along with the provision of a modular component ecosystem that allows for phone manufacturers and third party suppliers to provide users with modular components, allows a user to replace modular components rather than the entire phone when one of the modular components on the phone fails or becomes obsolete.
The concept of the modular phone provides for several advantages in online and/or mobile payments via phones and/or other user devices that are described in detail below.

DETAILED DESCRIPTION
The present disclosure provides modular device payment systems and methods for making payments using modular device payment modules that are configured to connect to a modular device frame of a modular device such as, for example, a modular phone. The payment module may provide a self-contained payment device that stores information about one or more funding sources, that may include one or more communication systems, and that provides a payment module engine that is configured to conduct payment transactions using the funding source information and the communication system(s). The payment module may store security information that ensures that the payment module cannot be used with unauthorized modular devices, and upon connection to a module device frame, the payment module may retrieve modular device identifying information from that modular device, determine whether it matches an authorized modular device identified by the security information and, if so, enable the transmission of the funding source information for conducting a payment transaction. If the modular device identifying information retrieved from the modular device does not match an authorized modular device identified by the security information, the payment module may take steps such as disabling the transmission of the funding source information, locking the payment module, and even erasing the funding source information and/or other information from the payment module. In addition, the payment module may include additional integrated or attachable features such as, for example, a biometric input device, a card reader, a card information provisioning member, and/or other payment and security features. In specific embodiments, the payment module may provide a highly secure, multiple virtual currency wallet management system that utilizes a virtual machine and physical or virtual cards that each store a respective virtual currency wallet and that operate to present multiple layers of authentication to protect virtual currencies that are accessible on the payment module.
Referring now to FIGS. 1a, 1b, and 1c, an example of a modular device 100 is provided that, in the illustrated embodiment, is a modular phone. However, as discussed below, the modular device/modular phone may be a variety of other modular devices known in the art. Furthermore, in some embodiments, the functionality discussed below with regard to the modular device may be provided in an integrated or non-modular user device while remaining within the scope of the present disclosure. The modular device 100 includes a modular device frame 102 having a plurality of module connectors 102a (both on a first side illustrated in FIG. 1a, as well as a second side that is not illustrated but that is located opposite the modular device frame 102 from the first side). While not illustrated, one of skill in the art in possession of the present disclosure will recognize that the modular device frame 102 houses a plurality of electrical connections, busses, and/or other links between the module connectors 102a to allow modules connected to the modular device frame 102 to communicate with each other, as discussed further below. The modular device 100 also includes a plurality of modules that, in the illustrated embodiment, include a display module 104 that includes modular device connectors 104a that are configured to engage the module connectors 102a on the modular device frame 102, a Wi-Fi communication module 106 (which includes modular device connectors, not illustrated, that are configured to engage the module connectors 102a on the modular device frame 102), a camera module 108 (which includes modular device connectors, not illustrated, that are configured to engage the module connectors 102a on the modular device frame 102), a speaker module 110 (which includes modular device connectors, not illustrated, that are configured to engage the module connectors 102a on the modular device frame 102), a battery module 112 (which includes modular device connectors, not illustrated, that are configured to engage the module connectors 102a on the modular device frame 102), a processing module 114 (which includes modular device connectors, not illustrated, that are configured to engage the module connectors 102a on the modular device frame 102), a security module 116 (which includes modular device connectors, not illustrated, that are configured to engage the module connectors 102a on the modular device frame 102), and/or other modules that are not referenced by reference numbers in FIGS. 1a, 1b, or 1c but which may include memory modules, other communication modules, any of a variety of computing components known in the art, and the payment module discussed below.
As illustrated in FIGS. 1a, 1b, and 1c, each of the modules may be connected to the modular device frame 102 to provide the modular device 100, and as discussed above, users may replace failed modules, add different modules, and upgrade modules depending on the user's desired functionality of the modular device 100. For example, if a storage module is running out of space, the user may upgrade the current storage module with a higher capacity storage module and connect it to the modular device frame 102. Furthermore, as discussed below, a payment module may be provided that connects to the modular device frame 102 and that may be configured to conduct payment transactions, either by itself (e.g., without the need to communicate with other modules connected to the modular device frame 102) or with the assistance of and/or utilizing communication with other modules connected to the modular device frame 102. While a specific modular device 100 has been illustrated and described, one of skill in the art in possession of the present disclosure will recognize that a wide variety of different types of modular devices having different form factors, different modular device frames, different module connection methods, and/or other different modular device characteristics will benefit from the teachings of the present disclosure and thus will fall within its scope.
Referring now to FIGS. 2a and 2b, an embodiment of a payment module 200 is illustrated. The payment module 200 includes a chassis 202 having a front surface 202a, a rear surface 202b located opposite the chassis 200 from the front surface 202a, a top surface 202c extending between the front surface 202a and the rear surface 202b, a bottom surface 202d extending between the front surface 202a and the rear surface 202b and located opposite the chassis 200 from the top surface 202c, and a pair of opposing side surfaces 202e and 202f extending between the front surface 202a, the rear surface 202b, the top surface 202c, and the bottom surface 202d and located opposite the chassis 200 from each other. A plurality of modular device connectors 204 extend from the rear surface 202b and are coupled to components housed in and/or provided by the payment module 200, discussed in further detail below. In the illustrated embodiment, a plurality of sub-module connections 206 are included on the payment module 202 and are coupled to components housed in and/or provided by the payment module 200. As discussed below, in some embodiments sub-modules may be coupled to the payment module 200 through the sub-module connections 206, while in other embodiments, the sub-module functionality discussed below may be integrated as part of the payment module 200.
Referring now to FIG. 3, an embodiment of a payment module 300 is illustrated that may be the payment module 200 discussed above with reference to FIGS. 2a and 2b. As such, the components included in and/or provided by the payment module 300 discussed below may be housed in the chassis 202 of the payment module 200. The payment module 300 may include a hardware processing system (not illustrated) and a non-transitory, computer-readable medium or memory system that includes instructions that, when executed by the hardware processing system, cause the hardware processing system to configure a payment module engine 302 that performs the functionality of the payment module engines and payment modules taught herein. The payment module 300 may also include one or more physical interfaces 304 (e.g., the modular device connectors 204 and/or the sub-module connections 206) that are coupled to the payment module engine 302 through, for example, a bus or other connection between the hardware processing system and the one or more physical interfaces 304. The payment module 300 may also include one or more wireless communication systems 306 such as, for example, a Wi-Fi communication system, a Bluetooth communication system or Bluetooth Low Energy (BLE) communication system, a Near Field Communication (NFC) system, a beacon communication system, and/or a variety of other wireless communications systems known in the art that are coupled to the payment module engine 302 through, for example, a bus or other connection between the hardware processing system and the wireless communication system 306. The payment module 300 also includes a payment module database 308 that stores funding source information 308a and security information 308b, discussed in further detail below, and that is coupled to the payment module engine 302 through, for example, a bus or other connection between the hardware processing system and a storage system that provides the payment module database 308.
While each of the components of the payment module 300 are illustrated as included in the payment module 300, in some embodiments at least some of the components of payment module 300 may be coupled to the payment module engine 302 through the one or more physical interfaces 304 and the modular device frame 102. For example, in some embodiments, the wireless communication system 306 may be included in the Wi-Fi communication module 106 and coupled to the payment module engine 302 through the one or more physical interfaces 304 and the modular device frame 102. As such, one of skill in the art in possession of the present disclosure will recognize that other components utilized by the payment module engine 302 as discussed below may be similarly provided as modules included on the modular device 100.
In some embodiments, the payment module 300 may be utilized in conjunction with a payment service provider such as, for example, PayPal Inc. of San Jose, Calif. For example, a payment service provider may utilize a payment service provider device to provide payment services to a user of the payment module. As in known in the art of payment services, one or more account providers utilizing account provider devices may provide funding source accounts such as checking accounts, savings accounts, credit accounts, and/or other payment accounts to the user. The user may then provide funding source information associated with those accounts provided by the account providers to the payment service provider (via the payment service provider device), and then use a payment service provider account to make payments that may be drawn from one or more of those funding sources. In addition, the payment service provider may provide payment accounts to the user as well for making payments.
In some embodiments, the funding source information 308a stored in the payment module database 308 may be provided by a user and may include any funding sources associated with a user and provided by the account providers and/or payment service providers discussed above. For example, a user may connect the payment module 300 to the modular device frame 102 of the modular device 100, provide a username and password (or other authentication information that may be verified by the payment module using the security information 308b in the payment module database 308) to authorize the payment module 300 to conduct payment transactions when connected to the modular device 100, and provide information about checking account funding sources (e.g., checking account numbers, etc.), savings account funding sources (e.g., savings account numbers, etc.), credit account funding sources (e.g., credit account numbers, expiration dates, security codes, etc.), and/or a variety of funding sources known in the art for authentication and storage in the payment module database 308. As such, when provisioned with funding source information, the payment module 300 may be considered an “electronic wallet” that stores information about any funding source that the user may wish to use with a merchant. Furthermore, the user may add and/or remove funding sources as desired to the payment module.
However, in some embodiments, the payment module 300 may be funding source specific such that it is only associated with a single funding source. For example, a credit account provider may provide the user with a credit account payment module that includes only funding source information associated with their credit account (e.g., a credit account number, expiration date, security code, etc.), and the user may provide authentication information substantially as described above to authorize that credit account payment module for use in conducting payment transactions when connected to the modular device frame 102 of the modular device 100. Similarly, the payment module may be solely a virtual currency wallet manager as discussed below. As such, the user may possess multiple funding-source-specific payment modules that may be connected to the modular device frame 102 depending on which funding source the user would like to use to conduct a payment transaction.
Referring now FIG. 4, an embodiment of a payment module 400 is illustrated that is substantially similar to the payment modules 200 and/or 300 discussed above with reference to FIGS. 2a, 2b, and 3, but with the provision of a biometric input system 402. The biometric input system 402 may be housed in and/or located on the chassis 202, and coupled to the payment module engine 302 through a bus or other connection between the hardware processing system and the biometric input system 402. In the illustrated embodiment, the biometric input system 402 is a thumbprint or fingerprint reader, but in other embodiments may include eye scanners, a facial capture and recognition system, and/or a variety of other biometric input systems known in the art. The payment module 400 illustrated in FIG. 4 provides an example of the payment module 200 with an integrated sub-module (i.e., a biometric input system sub-module), but in other embodiments the biometric input system sub-module may be coupled to the payment module 200 via the sub-module connectors 206. As discussed below, the biometric input system 402 allows for the user to authenticate with the payment module 400 to conduct payment transactions. As such, the user may register a biometric input with the payment module upon initial connection to a modular device by providing authentication information and then allowing the biometric input system 402 to receive and store a biometric input as part of the security information 308b in the payment module database 308.
Referring now FIG. 5, an embodiment of a payment module 500 is illustrated that is substantially similar to the payment modules 200 and/or 300 discussed above with reference to FIGS. 2a, 2b, and 3, but with the provision of a card sub-module 502 that includes a card information provisioning member 504 that extends from the card sub-module 502 and that includes an information transfer element 504a. In the illustrated embodiment, the card sub-module 502 is a separate sub-module that includes sub-module connectors (not illustrated) that engage the sub-module connections 206 on the payment module 200 to couple the card sub-module 502 to the payment module engine 302 through a bus or other connection between the hardware processing system and the sub-module connections 206, but in other embodiments the card sub-module 502 may be integrated with the payment module 500. The card sub-module 502 provides the card information provisioning member 504 with the information transfer element 504a configured to transfer funding source information to a card reader device. In some embodiments, the information transfer element 504a may be a conventional magnetic stripe information transfer element that is configured to provide card information to a card reader device. In other embodiments, the payment module engine 302 may be configured to dynamically program, push, or otherwise provide card information to the information transfer element 504a such that that card information may be transferred from the information transfer element 504a to a card reader when the card information provisioning member 504 is moved through the card reader (i.e., the user may select from different funding source information 308a in the payment module database 308 to have card information associated with a selected funding source be provided to the information transfer element 504a to, for example, provide a particular credit card number for a selected credit card account to the card reader using the card information provision member 504). The payment module 500 illustrated in FIG. 5 provides an example of a sub-module coupled to the payment module 200 via the sub-module connectors 206. However, as discussed above, the functionality of the card sub-module 502 may be integrated (i.e., without the ability to attached and detach the card sub-module 502 from the payment module chassis 202) with the payment module 200 while remaining within the scope of the present disclosure.
Referring now FIG. 6, an embodiment of a payment module 600 is illustrated that is substantially similar to the payment modules 200 and/or 300 discussed above with reference to FIGS. 2a, 2b, and 3, but with the provision of a card reader sub-module 602 that includes a card reader channel 604 that is defined by the card reader sub-module 602 and that includes an card reader element (not illustrated, but located in the card reader channel 604 as would be understood by one of skill in the art). In the illustrated embodiment, the card reader sub-module 602 is a separate sub-module that includes sub-module connectors (not illustrated) that engage the sub-module connections 206 on the payment module 200 to couple the card reader sub-module 602 to the payment module engine 302 through a bus or other connection between the hardware processing system and the sub-module connections 206, but in other embodiments the card reader sub-module 602 may be integrated with the payment module 500. In the illustrated embodiment, the payment module engine 302 is configured to receive card information from a card when a magnetic stripe or other information transfer element is moved through the card reader channel 604 and past the card reader element. As such, the payment module 600 may be utilized by a merchant for accepting payments in a payment transaction, rather than a customer providing payment in a payment transaction.
Referring now to FIG. 7, an embodiment of a payment module 700 is illustrated that is substantially similar to the payment modules 200 and/or 300 discussed above with reference to FIGS. 2a, 2b, and 3, but with the provision of a highly secure, multiple virtual currency wallet management system. The payment module 700 includes the payment module engine 302 that is coupled to a hypervisor 702 that may be provided by instructions on the non-transitory memory system that, when executed by the hardware processing system, cause the hardware processing system to perform the functionality of the hypervisor 702 and its subcomponents discussed below. One of those subcomponents includes a virtual machine 704 that is configured to be communicatively coupled to, or to otherwise access, a plurality of cards discussed below that may include, for example, secure digital (SD) cards and/or other storage cards known in the art. In an embodiment, the virtual machine 704 may be provided by a hardware processing system that is provided in the payment module 700 and that is dedicated to providing the virtual machine 704 (e.g., that is separate from the hardware processing system that provides the payment module engine 302), or may be provided by a virtualized processing module that is dedicated to providing the virtual machine 704. In the illustrated embodiment, the cards are virtual cards 706, 708, and up to 710, but in some embodiments the cards 706, 708, and 710 may be physical cards that are coupled to the payment module 700.
Each of the virtual cards includes a different virtual currency wallet by, for example, including a virtual currency wallet application that stores one or more private keys that provide the ability to transfer virtual currency associated with one or more public addresses, as is known in the art of virtual currency. For example, each virtual card may include a TrueCrypt (or similar) linked folder that stores the virtual currency wallet application on that virtual card. As such, virtual card 706 includes a first virtual currency wallet 706a, virtual card 708 includes a second virtual currency wallet 708a, and virtual card 710 includes an Nth virtual currency wallet 710a. In some embodiments, each of the virtual currency wallets 706a, 708a, and 710a may be associated with different types of virtual currency (e.g., virtual currency wallet 706a may provide access to Bitcoin, virtual currency wallet 708a may provide access to Litecoin, virtual currency wallet 710a may provide access to Dogecoin, etc.). In other embodiments, at least some of the virtual currency wallets 706a, 708a, and 710a may be associated with the same type of virtual currency (e.g., the first virtual currency wallet 706a may store one or more first private keys that provide the ability to transfer virtual currency (e.g., Bitcoin) associated with one or more first public addresses, and the second virtual currency wallet 708a may store one or more second private keys that provide the ability to transfer the same type of virtual currency (e.g., Bitcoin) associated with one or more second public addresses that are different from the one or more first public addresses).
The highly secure, multiple virtual currency wallet manager provided by the payment module 700 provides the ability to manage and store multiple virtual currency wallets of the same and/or different types of virtual currency, while presenting three security layers to a user attempting to access a virtual currency wallet to transfer virtual currency to another user. As discussed in further detail below, a user wishing to access any of the first virtual currency wallet 706a, the second virtual currency wallet 708a, or the Nth virtual currency wallet 710a must provide a first authentication to the virtual machine 704, then must provide a second authentication to the virtual card that stores the virtual currency wallet the user wishes to access, and must then provide a third authentication to the virtual currency wallet the user wishes to access. In addition, the virtual or physical cards may be cloned, backed up, or otherwise copied to a separate storage system (e.g., a physical storage device, the cloud, etc.) to ensure that failure, theft, loss, or other unavailability of the payment module does not threaten access to the virtual currency on any of those virtual cards.
Referring now to FIG. 8, an embodiment of a method 800 for conducting a payment transaction with a modular device payment module is illustrated. The method 800 begins at block 802 where the payment module is connected to the modular device. As discussed above, the payment module 200 may be connected to the modular device frame 102 of the modular device 100 by positioning the modular device connectors 204 on the payment module 200 adjacent the module connections 102a on the modular device frame 102 and moving the payment module 200 towards the modular device frame 102 to engage the modular device connectors 204 and the module connections 102a. Engagement of the modular device connectors 204 and the module connections 102a physically couples the payment module 200 to the modular device frame 102 and permits communication by the payment module engine 302 with the modular device frame 102 and other modules that are connected to the modular device frame 102.
The method 800 then proceeds to block 804 where modular device identifying information is retrieved. Prior to the method 800, the user may have defined, identified, or otherwise provided information about one or more authorized modular devices as part of the security information 308b in the payment module database 308. In an embodiment, a device identifier, phone number, unique code, user information, identifying information that includes identifiers that are associated with each of the modules that are connected to the modular device frame 102, and/or other information that uniquely identifies a modular device of the user may be provided to the payment module 200 for storage in the payment module database 308 as part of the security information 308b. For example, upon connecting the payment module 200 to a modular device frame as discussed above, and determining that the modular device is not authorized, discussed below, the payment module 200 may provide the user with the ability to authorize that modular device for the payment module 200 by requesting user authorization credentials (e.g., a user identifier and passcode, a biometric identifier, etc.). If those user authorization credentials are verified with credentials included in the security information 308b, the payment module 200 may then retrieve the identifying information from the modular device and associate it with an authorized modular device in the security information 308b. In addition, additional security may be provided for the payment module by sending authorized modular device information to a provider of the payment module (e.g., a payment service provider) and having the authorized modular device information stored in the security information 308b prior to providing the payment module to the user.
In an embodiment, the payment module engine 302 operates at block 804 to communicate with at least one of a component in the modular device frame 102 and/or another module that is connected to the modular device frame 102 to retrieve identifying information from the modular device 100. For example, identifying information about the modular device may be stored in the modular device frame 102 (e.g., in a storage device included in the modular device frame 102), in the security module 116 coupled to the modular device frame 102, and/or in other modules that are coupled to the modular device frame 102. The identifying information retrieved by the payment module engine 302 may include the device identifier, phone number, unique code, user information, and/or other information that was used to uniquely identify the modular device 100. In some examples, the identifying information may include identifiers that are associated with each of the modules that are connected to the modular device frame 102.
The method 800 then proceeds to decision block 806 where it is determined whether the modular device is authenticated for the payment module. In an embodiment, the payment module engine 302 compares the identifying information retrieved from the modular device 100 at block 804 with the security information 308b in the payment module database 308 to determine whether the identifying information matches an authorized modular device identified by the security information 308b. As such, the payment module engine 302 may determine at decision block 806 that the device identifier, phone number, unique code, user information or other information that uniquely identifies the modular device 100 matches device identifiers, phone numbers, unique codes, user information or other information that uniquely one or more modular devices in the security information 308b of the payment module database 308. In a specific embodiment, the security information 308b may include a plurality of identifiers for modules that define an authorized modular device 100, and at decision block 806 the payment module engine 302 may determine whether some subset of identifiers retrieved from each of the modules that are connected to the modular device frame 102 match some subset of the plurality of identifiers for modules that define an authorized modular device 100. As such, the identifiers for modules connected to the modular device frame 102 that are retrieved at block 804 may not all need to match all of the identifiers for modules that define an authorized modular device 100 as long as some minimum subset matches, which allows for authentication of the modular device 100 for the payment module 200 even if some of the modules on an authorized modular device 100 are replaced.
If, at decision block 806, it is determined that the modular device is not authenticated for the payment module, the method 800 proceeds to block 808 where a security action is performed. In an embodiment, the payment module 200 may determine at decision block 806 that the modular device 100 to which the payment module 200 was connected at block 802 is not authenticated for the payment module 200 (e.g., its identifying information is not associated with an authenticated modular device in the security information 308b) and, in response may perform a security action at block 808. Security actions may include preventing the transmission of any of the funding source information 308a in the payment modular database 308 for use in conducting a payment transaction, locking the payment module 200 such that further communication through the modular device frame 102 is disabled and/or to prevent a payment transaction from being conducted, erasing the funding source information 308a in the payment module database 308, wiping all information stored on non-transitory, computer-readable mediums in the payment module 200, and/or performing a variety of other security actions known in the art that would prevent any sensitive information on the payment module 200 from being accessed.
If, at decision block 806, it is determined that the modular device is authenticated for the payment module, the transmission of the funding source information 308a from the payment module database 308 is enabled. In an embodiment, the payment module engine 200 may enable, allow, and/or otherwise facilitate the transmission of funding source information 308a from the payment module database 308 in order to conduct a payment transaction, discussed in further detail below. Thus, a user of the payment module 200 may authorize any number of modular devices for use with the payment module 200, and then use the payment module with any of those modular devices while ensuring (via blocks 802-808) that loss or theft of the payment module will not allow its use with a non-authorized modular device.
The method 800 may then proceed to optional decision block 810 and block 814, where it is then determined whether a request to access a virtual currency wallet is received. Optional decision block 810 and block 814 illustrate a situation where the payment module 200 provides a virtual currency wallet manager that regulates access to multiple virtual currency wallets. However, in some embodiments, the payment module 200 may not include the virtual currency wallet manager taught herein, and following a determination at decision block 806 that the modular device 100 is authorized for the payment module 200, the method 800 may proceed directly to block 812. However, when the payment module 200 include the virtual currency wallet manager, a request to access a virtual currency wallet included on the payment module 200 may initiate additional security layers in the payment module 200. However, if at decision block 810 it is determined that no request to access a virtual currency wallet has been received, the method 800 proceeds to block 812 where a payment transaction is conducted.
In an embodiment, at block 812 the payment module engine 302 may receive a request to conduct a payment transaction and, in response, retrieve at least some of the funding source information 308a to conduct the payment transaction. As discussed above, prior to the method 800, the payment module 200 may provide the user to ability to add funding sources to the payment module database 308 that are then stored in the funding source information 308a. For example, the user may add checking funding source(s) to the funding source information 308a (e.g., by providing checking account information needed to conduct a payment transaction using checking (s)account of the user), savings funding source(s) to the funding source information 308a (e.g., by providing savings account information needed to conduct a payment transaction using savings account(s) of the user), credit funding source(s) to the funding source information 308a (e.g., by providing credit account information needed to conduct a payment transaction using credit account(s) of the user), and/or any other funding sources known in the art to the funding source information.
Requests to conduct a payment transaction may be received in a variety of manners, and will typically result in a payment transaction conducted with a merchant through a merchant device, but will sometime result in a payment transaction conducted with another user through their user device. In an embodiment, the payment module 300 may use the wireless communication system 306 to receive a request to conduct a payment transaction. For example, the user of the modular device 100 may bring the modular device 100 and payment module 200 within range of an NFC or other wireless payment system in order provide a request to the payment module 200 to conduct a payment transaction, and the payment module 200 may then communicate with the payment system to transmit funding source information to the payment system in order to conduct the payment transaction (e.g., via the wireless communication system(s) 306 in the payment module 300, using a communication module connected to the modular device frame 102, etc.). In such embodiments, a payment application may be provided for display on the display module 104 to the user to allow the user to select a funding source for conducting the payment transaction, or the payment module 200 may default to a particular funding source.
In another embodiment, the payment module 200 may communicate with another payment module (i.e., on another modular device) to receive a request to conduct a payment transaction. For example, the user of the modular device 100 may bring the modular device 100 within range or into engagement with another modular device (e.g., via a “bump” or other touching of the modular devices) in order provide a request to the payment module 200 to conduct a payment transaction, and the payment module 200 may then communicate with the payment module in the other modular device to transmit funding source information to the payment system in order to conduct the payment transaction. In such embodiments, a payment application may be provided for display on the display module 104 to the user to allow the user to select a funding source for conducting the payment transaction, or the payment module 200 may default to a particular funding source.
In another embodiment, the user may utilize a payment application provided for display on the display module 104 to select a funding source for conducting the payment transaction, and the payment module 200 may provide funding source information for that funding source to the card sub-module 502 for transmission using the information transfer element 504a on the card information provisioning member 504. As such, the user may select one of a plurality of credit cards, checking cards, rewards cards, discount cards, gift cards, or other cards to have information for the selected card provided on the information transfer element 504a such that when the user moves the card information provisioning member 504 through a card reader, the information for the selected card is provided to the card reader for conducting the payment transaction.
While a few examples have been provided, one of skill in the art in possession of the present disclosure will recognize that the payment module 200 may retrieve funding source information 308a from the payment module database 308 and conduct the payment transaction at block 812 using any of a variety of methods known in the art that will fall within the scope of the present disclosure. In addition, other payment activities may be performed by the payment module engine 302 in the payment module 300, including bill splitting (e.g., by touching payment modules on different modular devices, etc.), account information retrieval and review, and/or other payment activities known in the art.
If, at decision block 810, a request to access a virtual currency wallet is received, the method 800 then proceeds to block 814 where a plurality of security layers are authenticated. Referring now to FIGS. 9a, 9b, 9c, 9d, and 9e, an example of receiving a request to access a virtual currency wallet and, in response, authenticating a plurality of security layers is illustrated and described. However, a variety of manners for receiving requests to access virtual currency wallets and authenticate security layers other than those illustrated are envisioned as falling within the scope of the present disclosure.
Referring now to FIG. 9a, a modular device 900 is illustrated that may be the modular device 100 discussed above with reference to FIG. 1. However, in some embodiments, the functionality described as performed by the payment module engine 302 in the payment module 200 coupled to the modular device 900 may instead be performed by a payment engine located in an integrated user device such as a non-modular phone or other user device. The modular device 900 includes a display module 902 that may be, for example, the display module 104 discussed above. In the illustrated embodiment, the display module 902 is displaying a home screen 904 that includes a plurality of application icons including a virtual currency wallet management application icon 906. In embodiment, the user of the modular device 900 may select the virtual currency wallet management application icon 906 and, at decision block 810, the payment module engine 302 will detect a request to access a virtual currency wallet. In other embodiments, rather than having a virtual currency wallet manager, the home screen 904 may instead include virtual currency wallet application icons that, when selected by the user, cause the payment module engine 302 to detect a request to access a virtual currency wallet at decision block 810.
Referring now to FIG. 9b and with reference to FIG. 7, the modular device 900 is illustrated with the display module 902 displaying a first security layer screen 908 that may be provided by the virtual machine 700 and the payment module engine 302 at block 814 of the method 800. For example, in response to the user selecting the virtual currency wallet management application icon 906 (or a virtual currency wallet application icon), the payment module engine 302 may communicate with the virtual machine 704 to access the virtual currency wallets included in the virtual cards 706, 708, and 710 accessible by the virtual machine 704, and the virtual machine 704 may present a first security layer using the first security layer screen 908. The first security layer screen 908 includes a first authentication request section 908a that provides a user identifier input 908b and a password input 908c, and that requests that the user provide a username and password to access the virtual currency wallets. In order to access the virtual currency wallets, the user must provide the correct username and password to pass the first security layer presented by the virtual machine 704, and the payment module engine 302 and/or the virtual machine 704 may receive any username and password provided in the user identifier input 908b and a password input 908c, compare it to the security information 308b in the payment module database 308, and authenticate the user for the first security layer in response to determining that a provided username and password are associated with a user that is authorized to access the virtual currency wallets. While a username and password are illustrated as necessary for authenticating at the first security layer, any authentication technique is envisioned as falling within the scope of the present disclosure.
Referring now to FIG. 9c, in response to determining that a provided username and password are associated with a user that is authorized to access the virtual currency wallets, the display module 902 on the modular device 900 may display a virtual currency wallet application icon screen 910 that includes a plurality of virtual currency wallet application icons 910a, 910b, and 910c. In the illustrated embodiment, the virtual currency wallet application icons 910a, 910b, and 910c are associated with different virtual currency wallets holding different types of virtual currency (e.g., a Bitcoin wallet, a Litecoin wallet, and a Dogecoin wallet). However, any number of virtual currency wallets may be included in the virtual machine 702, and may be hold different types of virtual currency or the same types of virtual currency (e.g., there may be multiple virtual currency application icons on the virtual currency wallet application icon screen 910 that hold Bitcoins). In response to being presented the virtual currency wallet application icon screen 910, the user may select the virtual currency wallet application icon for the virtual currency wallet that the user wishes to access in order to, for example, conduct a payment transaction.
Referring now to FIG. 9d, and with reference to FIG. 7, the modular device 900 is illustrated with the display module 902 displaying a second security layer screen 912 that may be provided by one of the virtual cards 706, 708, or 710 and the payment module engine 302 at block 814 of the method 800. For example, in response to the user selecting the virtual currency wallet application icon 910a (i.e., the Bitcoin wallet in FIG. 9c), the payment module engine 302 may communicate with the virtual card 706 (e.g., via the virtual machine 704) to access the first virtual currency wallet 706a included in the virtual card 706, and the virtual card 706 may present a second security layer using the second security layer screen 912. The second security layer screen 912 includes a second authentication request section 912a that provides a plurality of pattern elements, and that requests that the user use the pattern elements in order to access the first virtual currency wallet 706a. In order to access the first virtual currency wallet 706a, the user must draw a pattern by connecting the pattern elements to pass the second security layer presented by the virtual card 706, and the payment module engine 302 and/or the virtual card 706 may receive any pattern provided using the pattern elements, compare it to the security information 308b in the payment module database 308, and authenticate the user for the second security layer in response to determining that a provided pattern associated with a user that is authorized to access the first virtual currency wallet 706a. While a pattern using pattern elements is illustrated as necessary for authenticating at the second security layer, any authentication technique is envisioned as falling within the scope of the present disclosure.
Referring now to FIG. 9e, in response to determining that a provided pattern is associated with a user that is authorized to access the first virtual currency wallet 706a, the display module 902 on the modular device 900 may display a third security layer screen 914 that may be provided by the first virtual wallet application 706a and the payment module engine 302 at block 814 of the method 800. For example, in response to the user providing an authenticated pattern, the payment module engine 302 may communicate with the first virtual wallet application 706a (e.g., via the virtual machine 704 and the virtual card 706) to access the first virtual currency wallet 706a included in the virtual card 706, and the first virtual currency wallet 706a may present a third security layer that includes a third authentication request section 914a that provides a request that the user provide a biometric input in order to access the first virtual currency wallet 706a. In order to access the first virtual currency wallet 706a, the user must provide a biometric input to a biometric input system (e.g., a thumb scan on the biometric input system 402 discussed above) to pass the third security layer presented by the first virtual currency wallet 706a, and the payment module engine 302 and/or the first virtual currency wallet 706a may receive the biometric input provided, compare it to the security information 308b in the payment module database 308, and authenticate the user for the third security layer in response to determining that a biometric input is associated with a user that is authorized to access the first virtual currency wallet 706a. While a biometric input is illustrated as necessary for authenticating at the third security layer, any authentication technique is envisioned as falling within the scope of the present disclosure.
Following being authenticated to pass the third security layer, the method 800 may proceed to block 812, discussed in detail above. However, in addition to being able to conduct conventional payment transactions as discussed above, the user may now also be able to conduct payment transaction using the first virtual currency wallet 706a by, for example, transferring virtual currency to another user by designating a public address of that user, designating a virtual currency amount, and providing a private key for the first virtual currency wallet 706a such that the first virtual currency wallet may transfer the designated amount of virtual currency to the public address associated with the other user. As discussed above, while specific security layers including usernames and passwords, pattern provisioning, and biometric inputs have been illustrated and described, any of authentication techniques may be utilized in authenticating the plurality of authentication levels at block 814. It has been found that the three (or more) security layers provide practically insurmountable security for the virtual currency wallets stored on the payment module 200.
Thus, systems and methods for conducting payment transactions using a modular device payment module have been described that provide a payment module that may be connected to a modular device, and that operates to ensure that the modular device is authorized for use with the payment module prior to enabling payment transactions with funding sources available to the payment module. In the event the modular device is not authorized for use with a payment module to which it is connected, the payment module may perform security operations that include disabling the access to or transmission of funding source information, locking access to the payment module, and even erasing the funding source information (or all the information) from the payment module. Furthermore, systems and methods for managing multiple virtual currency wallets have been described that manage multiple virtual currency wallets that may hold different types of virtual currency, while providing multiple security layers that require authenticated credentials in order to access to any of the virtual currency wallets.
