Disclosed are methods for exchanging transaction data, including transmitting a first public encryption key from a first computing device via a near field communication (NFC) connection, receiving transaction data associated with a transaction at the initiating device via the NFC communication connection, generating a transaction message associated with the transaction based on the transaction data associated with the transaction and the first public encryption key, encrypting at least a portion of the transaction message associated with the transaction with a second public encryption key; determining that a network communication connection to a payment processing network different from the NFC communication connection can be established, and transmitting the transaction message via the network communication connection based on determining the network communication connection to the payment processing network can be established. A system and a computer program product are also provided.

Some examples of the present disclosure relate to generating artificially intelligent entities represented on a blockchain using a non-fungible token (NFT). In one such example, a system can generate an NFT on a blockchain. The NFT can represent an artificially intelligent entity. The system can also generate a personality dataset on the blockchain, the personality dataset describing personality characteristics of the artificially intelligent entity. The system can then correlate the NFT to the personality dataset, thereby assigning the personality characteristics to the artificially intelligent entity. Once generated, the artificially intelligent entity may reside in a virtual ecosystem in which it can perform tasks and learn over time.

Methods may involve accepting pre-manufacture verification of manufacturer capabilities and product precursors for a product. Discrete packets of operational parameters to enable an additive manufacturing device to manufacture the product may be generated, each packet enabling manufacture of a respective portion of the product. The respective packets may be sent for only after receipt of confirmation that a previous packet is complete and associated operational parameters for the previous packet have been deleted. A time from completion of the previous packet may be sufficient to ensure that manufacture of another respective portion of the product may begin without interruption in an additive manufacturing process. In-manufacture verification of operational parameters utilized by the additive manufacturing device may be accepted. During at least some stages, a blockchain may be updated to associate data representative of workflows for the product with an encrypted, secure identifier utilizing a secure, distributed transaction ledger.

Methods may involve sending identification of a product to an additive manufacturer. Confirmation from the additive manufacturer of availability may be received. Approval of a respective additive manufacturer may be confirmed. Discrete packets of operational parameters to enable an additive manufacturing device to manufacture respective portions of the product may be generated. Respective packets of operational parameters may be encrypted and sent to a network-connected additive manufacturing device. The respective packets may be sent only after confirmation that a previous packet is complete and has been deleted. A time from completion of the previous packet may be sufficient to ensure that manufacturing of another portion of the product may begin without interruption in an additive manufacturing process. During at least some stages, a blockchain may be updated to associate data representative of workflows for the product with an encrypted, secure identifier utilizing a secure, distributed transaction ledger.

Methods may involve maintaining a first secure, distributed transaction ledger including a digital inventory of product designs for industrial products. A second secure, distributed transaction ledger including a digital record of an entity's physical inventory of industrial products may be maintained. The second secure, distributed transaction ledger may be synced with a remote copy. A third secure, distributed transaction ledger including a digital record of precursors for manufacturing the product designs in the digital inventory may be maintained. The first, second, and third secure, distributed transaction ledgers may be interrelated and updated to associate digital records of at least some industrial products in the physical inventory of the second secure, distributed transaction ledger with corresponding product designs in the digital inventory of the first secure, distributed transaction ledger and digital records of corresponding precursors in the third secure, distributed transaction ledger.

A method for transaction handoff includes: registering a payment instrument with a server, associating the payment instrument with ephemeral tokens, and storing a payment token that associates the ephemeral tokens with the payment instrument and a device identifier in a database record; via a device, receiving an ephemeral token from the server; via a point-of-sale (POS) terminal, scanning the ephemeral token, and transmitting ephemeral token via the internet cloud to the server; via the server, using the payment token to access the device identifier and transmitting a push notification; upon acceptance of the push notification, executing an application on the device and simultaneously displaying transaction details on both the device and POS terminal; receiving completion data that is entered via the device and transmitting the completion data to the server; and completing the transaction at the server and notifying the POS terminal and the device that the transaction is complete.

Systems and methods are provided to allow a smart phone or any terminal to activate a lock using a web site or server computer system. An access control system is provided that includes a server and an access device. The access device includes a processor and a communication module. The process has control of a lock and is able to receive a reservation certificate presented by a portable terminal through the communication module. The processor activates the lock when a current reservation certificate has been presented.

Embodiments of the invention relate to systems and methods for provisioning and using a multi-purpose device. The device contains information regarding a plurality of memberships. The device contains one or more membership certificate chains, comprising multiple certificates, wherein a membership provider certificate is signed by a private key associated with a membership root certificate authority, and wherein a member certificate is signed by a private key associated with the membership provider certificate. The member certificate includes member attributes regarding the user, such as member benefit information. The device also includes a payment certificate chain, comprising multiple certificates, wherein a payment provider certificate is signed by a private key associated with a payment root certificate authority, and wherein a payment certificate is signed by a private key associated with the payment provider certificate. The payment certificate includes payment attributes regarding the user, such as a payment account.

An apparatus comprises at least one integrated circuit. The apparatus has a size and shape substantially similar to an ordinary Subscriber Identification Module (SIM) card. The at least one integrated circuit comprises a memory storing first software that, when executed, causes the card to communicate with second software stored on the device. The second software, when executed, causes the device to provide both a SIM and Payment Security Application Module (PSAM) functionality to a user of the device.

Systems and methods for enabling and enforcing cryptocurrency transactions associated with at least a portion of data are provided. Systems and methods may include a cryptocurrency transaction service, the cryptocurrency transaction service including one or more transaction servers and one or more ledger processing devices. At least one streaming server configured to associate at least a portion of data with a cryptocurrency transaction and to transmit the at least a portion of data may be provided. A client device may be provided, the client device being configured to receive the at least a portion of data from the streaming server, wherein at least one of the client device and at least one streaming server are configured to initiate a cryptocurrency transaction with the cryptocurrency transaction server based at least in part on the association between the at least a portion of data, the cryptocurrency transaction, and the cryptocurrency transaction service.
