DETAILED DESCRIPTION
[0039] In the following description of the various embodiments to accomplish the foregoing, reference is made to the accompanying drawings, which form a part hereof, and in which is shown by way of illustration, various embodiments in which the disclosure may be practiced. It is to be understood that other embodiments may be utilized and structural and functional modifications may be made.
[0040]
[0041] The card 100 may constitute a plastic laminate or metallic laminate. Alternatively, the card 100 could be constructed or constituted in accordance with any other known method of providing debit or credit cards or structure for such cards. The card 100 may include indicia 102 that identifies the issuer of the card or the holding source or manager for the digital currency store.
[0042] Various forms of machine-readable mechanisms that perform various machine functionality may be provided on or embedded in the card 100. For example, the card 100 may include a magnetic strip 104 for identifying the non-checking non-savings prepaid digital currency store 340 or other prepaid account associated with the card and/or the issuer 102. Encrypted non-volatile memory 106 may also be provided to store digital currency information, account information, blockchain information, currency store information, wallet information, or the like. The memory 106 may be used in conjunction with other components and systems to provide cold storage of currency as described in more detail infra.
[0043] One or more secure wireless NFC and/or UWB geo-locating semiconductors 108 may be used to enable NFC and/or UWB devices to triangulate or otherwise detect and locate the card 100 if it is lost or stolen. One or more secure wireless communication transaction semiconductors 110 can be used to facilitate wireless transactions and communications between the card 100 and ATMs 316 and/or POS machines 328. One or more scannable QR codes 112 (and 202 as in
[0044] One or more security chips 114 may also be provided to secure non-wireless communications between the card 100 and ATMs 316 and/or POS machines 328 such as, for example, when the card 100 is physically inserted into an ATM or POS reader.
[0045] If desired, the owner name 116 of the prepaid banking account may be printed on the card 100. The prepaid banking account number or corresponding card number 118 may also be printed on the card 100. Or, for security or privacy reasons, the owner name 116 and account information 118 may be omitted from the card. Owner lost card and/or contact information 200 may also be identified on the card 100 if desired.
[0046]
[0047] The prepaid electronic funds transferring system may include prepaid banking card 100, which is linked to the prepaid digital currency store 340 and/or other non-checking non-savings account. The prepaid electronic funds transferring system may also include a smartphone or like mobile device 300 with corresponding digital wallet 304 or processing functionality.
[0048] The mobile device 300 may include volatile and/or non-volatile memory 302 to store a digital wallet 304 (or implement digital wallet functionality) and a prepaid banking app 305. The wallet 304 may be a separate module in memory or may be included as part of the prepaid banking app 305. Private and/or public encryption keys 306 may be generated and/or stored electronically in memory 302 using standard cryptography. Preferably, prepaid banking server 400 will generate both a private and public encryption key and will communicate the keys with the prepaid banking app 305 over the Internet 314 during setup of the non-checking non-savings prepaid account. QR codes 307 may also be generated by the server 400 and used by the app 305 on the mobile device 300. The QR codes 307 may identify an issuing entity, a prepaid banking account, a number corresponding to the prepaid banking account, a public encryption key, and/or a private encryption key. The QR codes 307 (or 112 and 202 as printed on the card) may be used to implement cold storage for the prepaid digital currency store on the card 100 and/or be linked to implement hot storage for the prepaid digital currency store.
[0049] In simple terms, cold storage in the context of this disclosure refers to keeping a user's digital currency store completely offline. Cold storage, also known as a cold storage wallet, is the opposite of a hot wallet where a digital currency store is kept online. Keeping a digital currency store online increases a user's risk for the asset to be stolen when kept online using a custodial service. Accordingly, cold storage may be beneficial. By keeping the digital currency store in cold storage, attack threat vectors may be diminished.
[0050] Funds may be added to the non-checking non-savings digital currency store 340 in cold storage by, for example, scanning a QR code or copying an address and sending the funds to the digital currency store. Funds may be similarly sent by importing a private key for a digital wallet that is online. Any wallet that supports importing private keys will work.
[0051] The non-checking non-savings prepaid digital currency store 340 may be implemented in various ways on the mobile device 300 and/or unified card 100. For example, it may be stored and handled in digital wallet 304 in memory 302 on mobile device 300 and/or in encrypted non-volatile memory 106 on card 100. Or it may reside in a prepaid banking app 305 in memory 302. It can be secured and/or accessed with encryption keys 306, QR codes 112, 202, 307. Security chip(s) 114 may also be used to store or otherwise secure the digital currency store 340. Alternatively, the non-checking non-savings prepaid digital currency store 340 may be implemented partially and/or entirely on prepaid banking server 400.
[0052] Hardware on the mobile device 300 may include one or more processor(s) 308 which can access the memory 302 and execute computer-executable instructions in memory corresponding to the functions or modules of the digital wallet 304, prepaid banking app 305, encryption key(s) 306, and/or QR codes 307. The processors 308 can communicate directly with memory 302 via a bus or the like through communication interface(s) 310. The processors can also access near-field communications (NFC) and/or ultra-wideband (UWB) hardware 311 in the mobile device 300 to facilitate communications with ATMs 316 and POS machines 328, and can also be used to geo-locate the card 100 or the mobile device 300 if lost via NFC and/or UWB triangulation, networking, or the like. The mobile device 300 may also include a camera or scanner 312 to scan gift cards or QR codes to facilitate transfers, debits, deposits, or credit transactions.
[0053] The mobile device 300 may interact wirelessly with card 100 such as, for example, by Bluetooth, Wi-Fi, UWB, and/or NFC through NFC/UWB hardware 311 or communication interface(s) 310, and corresponding secure wireless communication transaction semiconductors 110. Smartphone 300 may also interact wirelessly with card 100 by scanning one or more QR codes 112, 202 on card 100 via a camera or scanner 312.
[0054] Similarly, smartphone 300 and/or unified card 100 may interact wirelessly with ATM 316 such as, for example, by Bluetooth, Wi-Fi, UWB, and/or NFC through NFC/UWB hardware 311 or communication interface(s) 310, and/or secure wireless communication transaction semiconductors 110. Smartphone 300 may also interact wirelessly with ATM 316 by scanning one or more QR codes 112, 202 displayed on the ATM screen 316 via a camera or scanner 312. Conversely, the ATM 316 can scan or read QR code(s) 307 on the mobile device 300 or codes 112, 202 on card 100.
[0055] Relatedly, smartphone 300 and/or unified card 100 may interact wirelessly with a POS machine 328 to, for example, make purchases from a merchant. Wireless communication may be accomplished by Bluetooth, Wi-Fi, UWB, and/or NFC through NFC/UWB hardware 311 or communication interface(s) 310, and/or secure wireless communication transaction semiconductors 110. POS machine 328 may also be able to scan or read QR code(s) 307 on the mobile device 300 or codes 112, 202 on card 100. Secure non-wireless communication between card 100 and POS machine 328 can be facilitated by security chip(s) 114 that secure transactions when the card 100 is inserted physically into a POS machine 328.
[0056] Preferably, mobile device 300 is connected either via cellular service and/or Wi-Fi to Internet 314. And, mobile device 300, ATM 316, blockchain device(s)/ledger(s) 338, prepaid banking servers 400, merchant POS machine(s) 328, may all communicate directly with one another or through Internet 314.
[0057] As used herein, blockchain in the context of blockchain device(s)/ledger(s) 338, at a high level, can be considered to be a type of database. The blockchain collects information together in groups, also known as blocks, that hold sets of information regarding the digital currency store. Blocks have certain storage capacities and, when filled, are chained onto the previously filled block, forming a chain of data known as the “blockchain.” All new information that follows that freshly added block is compiled into a newly formed block that will then also be added to the chain once filled. The blockchain, structures its data (e.g., prepaid digital currency store and/or information corresponding to the same) into blocks that are chained together. This makes it so that all blockchains are databases but not all databases are blockchains. This system also inherently makes an irreversible timeline of data for the prepaid digital currency store when implemented in a decentralized nature. When a block is filled it is set in stone and becomes a part of this timeline. Each block in the chain is given an exact timestamp when it is added to the chain.
[0058] A sample transaction process for implementation of blockchain device(s)/ledgers 338 in the context of this disclosure is shown in
[0059]
[0060] As an example, prepaid banking server 400 may utilize user authentication and/or hardware validation module(s) 403 in order to authorize mobile devices 300 to access the server 400 and/or to proceed with transactions on validated and/or registered devices 300. Prepaid digital currency transaction(s) received directly from mobile app 305 or indirectly via use of unified card 100 from may be stored in memory 402 and/or processed in module 404. Network communication module(s) 406 may facilitate direct communications between banking server 400 and mobile device 300 via network communication interface(s) 424, or indirectly with card 100. User information, hardware information, encryption keys, session information, digital currency store prepaid account information, ATM information, POS information, reward information, interest information, etc. may be communicated via module(s) 406 and interface(s) 424.
[0061] Public and private encryption keys received from, generated by, and/or distributed by the prepaid banking server 400 can be stored in module 408 and used to enable establishment and securing of communications between servers 400, ATMs 316, POS machines 328, mobile devices 300, and/or unified card 100.
[0062] One or more modules 410 may be used to provide detection, location determination, and/or facilitate communication with mobile devices 300 or unified card 100 via NFC/UWB hardware interfaces in ATMs or the like. Such detection of NFC/UWB devices may occur if and/or when the device 300 and/or card 100 comes within NFC/UWB of various devices 600, 602, 604, 606 which can then be communicated to server 400 and the location information for the device 300 or card 100 can be shared with a user, directly or indirectly, to locate a lost card.
[0063] Input/output (I/O) and/or wireless communication module(s) 412 in memory 402 may be used to accept inputs via optical scanner 426, touchscreen display 428, keypad 432, and/or voice recognition microphone 436 or the like. Messages may be communicated via display 428 or speaker 434 and/or wirelessly to devices such as, for example, smartphone 300.
[0064]
[0065] User authentication module(s) 502 can be used by the device 300 in communication with ATMs 316 and banking servers 400 in order to authenticate the user in order to establish a session and/or recognize a device 300 corresponding to a user who has a non-checking non-savings prepaid digital currency store or like account. Prepaid banking app module(s) 304, 504 executed on processor(s) 528, can be used to facilitate execution of digital currency store transactions as well as to provide haptic feedback via haptic feedback module(s) 520 and haptic feedback mechanism(s) 526 if desired for such transactions. Similarly, processor(s) 528 may execute instructions to perform the functionality of any of the module(s) stored in memory 501. One type of preferable haptic feedback would be if the card 100 is out of wireless communication with device 300. This would prevent loss of the card if, for example, it was left at a location and the user walked away.
[0066] Transaction processing/storage module(s) 506 on device 300 can be used to set up a prepaid transaction, store a previously set up prepaid transaction, and/or locally handle a prepaid transaction at an ATM 316 or POS machine 328. Wireless/network communication module(s) 508 and/or NFC/UWB functionality module(s) 512 can provide wireless local communication between the device 300, ATM 316, POS machine 328, and/or banking server 400 via network communication interface(s) 530 or the like.
[0067] Local public/private key encryption module(s) 510 may store key(s) received from banking server(s) 400 and/or generate keys that are communicated to server(s) 400 and thereafter distributed to ATMs 316 and/or POS machines 328. Either way, the public and private encryption keys stored in module(s) 510 can be used to establish and facilitate secure communications with device 300 via interfaces 524 and/or 530, and communication module(s) 508, 514.
[0068] As noted above, the non-checking non-savings prepaid digital currency store 340 may be implemented in various ways on the mobile device 300 and/or unified card 100 such as, for example, in digital currency store module 518, digital wallet module 516, and/or in prepaid banking app module 504 in memory 302.
[0069] Input to device 300 and/or output displays to provide information to the user may be accomplished through a touchscreen or non-touchscreen display 532, an optical scanner 534 such as for facial recognition or barcode or QR code scanning, a fingerprint scanner 536, and/or user interface/keypad 538. A speaker 540 may be included in device 300 to provide audible information and/or feedback to the user. If desired, the haptic feedback conveyed herein may provided audibly. A voice-recognition microphone 542 may also be included in 300 to enable voice commands or dictation in order to obviate, in whole or in part, manual key entries or manual interactions with the device.
[0070]
[0071] As noted previously, unified card 100 is preferably enabled with secure wireless communication semiconductor(s) 108 that are able to communicate by NFC and/or UWB with geographically distributed NFC/UWB enabled devices 600, 602, 604, 606. This communication allows triangulation or other location detection of the unified card 100 when within wireless range of one or more devices 600, 602, 604, 606. The location information may be provided to mobile device 300 directly via Wi-Fi, Bluetooth, NFC, and/or UWB, and/or provided indirectly to banking server 400 via Internet 314, which can then relay the location information and potentially directions 608 for the lost card 100 to mobile device 300 via the Internet 314.
[0072]
[0073]
[0074] In step 800, an institution or holding facility can provide a secure unified prepaid banking card 100 to the user. A prepaid banking server 400 can link a non-checking non-savings prepaid account to the card 100 in step 802, fund the prepaid account with an initial or other amount in step 804, provide interest on some or all funds held in the prepaid account in step 806, process debit requests in step 808 and/or credit requests in step 820 from ATMs 316 or POS machines 328 if the debit/credit request is equal to or less than the amount in the prepaid account, and process deposit requests in step 810 for deposits received at an ATM 316 or other means.
[0075] The prepaid banking server 400 can receive electronic transfers to the prepaid account in step 812 and can deposit in the prepaid account the electronic transfers preferably without requiring the user to download a prepaid banking server app or other app to the user's smartphone in step 814. Wireless communication between the card 100, smartphone 300, ATMs 316, and/or POS machines 328 can be accomplished via Bluetooth, Wi-Fi, UWB, NFC, or the like in secure wireless transaction semiconductor(s) 110. Geo-locating of the card, if lost, can similarly be accomplished by wireless means in step 816 by secure wireless NFC/UWB geo-locating semiconductor(s) 108. Communications between the card and/or smartphone and either ATMs or POS machines can be secured with one or more security chip(s) 114 to secure both wireless and/or non-wireless communications in step 818. Rewards for credit purchases may be processed in step 822.
