Disclosed is a system and method for implementing a network enabling an interoperable exchange of electronic payment information, which connects two parties to a transaction using established rules, technology, and trust model. Such systems and methods provide a shared set of rules and common APIs, and enable validation of the accuracy of all data exchanged via API. In order to maintain data, the systems and methods described herein enable each participant to only see interactions and information that is relevant and permissioned to such participant, all while maintaining no central data store for the sensitive electronic payment information. Each participant is vetted and authorized by a system administrator as a validated “Credential Service Provider” (“CSP”) and governed by rules created and managed by the administrator. Further, an auditable trail of all transactions is maintained by logging metadata to track events and changes to permissions.

The present disclosure relates to systems, non-transitory computer-readable media, and methods for a secure way of new products release, analyzing and measuring products demand, and tracking purchases for a product campaign prior to manufacturing. In particular, in one or more embodiments, the disclosed systems create a smart contract between a single seller and multiple buyers. The smart contract is recorded in a blockchain ledger, which is publicly available and difficult or impossible to modify after being recorded.

This disclosure is directed to receiving a request for attesting security of a device, determining to approve the request based on attestation data associated with the device, generating a ticket having validity conditions, and sending the ticket to the device to enable the device to receive payment data from a second device.

An access device is provided for use in an access control system. The access device includes a processor having control of a door lock, and a communication module connected to the processor. The processor is able to receive a reservation certificate presented by a portable terminal through the communication module. The processor activates the door lock when the current reservation certificate has been presented and disables an alarm system when the current reservation certificate has been presented.

To simply promote a commodity transaction by a transaction of an article, an article housing system includes a storage body that houses articles and an information processing device that is connected to the storage body, in which the storage body includes a notification unit that notifies the information processing device of link information of an article collected by a user and the user, and the information processing device includes a recording unit that records that the user picks up the article on the link information, and a settlement unit that executes settlement processing of allowing a payer linked with the user to pay for the article.

Systems and methods for multi-merchant tokenization may include receiving a transaction from a point of sale terminal of a merchant, validating the merchant ID against merchant logs, and generating a token for the transaction. The token includes a primary account number, expiration, and a group ID. Additionally, the system provides the primary account number to a payment system and receives a response back. The response is then output back to the merchant along with the token. In subsequent transactions, the system may receive the token from a one point of sale terminal of the merchant. The system validates the merchant ID against merchant logs and ensures the merchant is configured for tokenization. The token is decrypted and the group ID is compared to the merchant ID in the merchant logs. When they match, the primary account number is provided to the payment system for approval.

An issuing entity for issuing electronic coin data sets in a payment system, includes a coin generating unit, which is designed to generate an electronic coin data set, and a coin output unit, which is designed to obtain the electronic coin data set generated by the coin generating unit and output the electronic coin data set to a participating unit or to a bank entity of the payment system in electronic form. The issuing entity is designed such that the electronic coin data set is transmitted between the coin generating unit and the coin output unit via an air gap process. An issuing method and a payment system adopt features of the issuing entity.

Techniques associated with a dual state merchant-facing device are described herein. A point-of-sale system can comprise multiple devices, such as a customer-facing device and a merchant-facing device that is coupled to the customer-facing device and can operate in a first state or a second state. In at least one example, the merchant-facing device operating in the first state can present a graphical user interface (GUI) on a display. The merchant-facing device can transition from the first state to the second state, the second state enabling the merchant-facing device to perform at least one additional functionality that is not available to the merchant-facing device in the first state, and can update the GUI based at least in part on the at least one additional functionality.

A first logic circuit included in a processor receives a first digital signal, where the first logic circuit includes a special purpose register, a comparator, and an adder, where the special purpose register stores a first resource balance for executing a smart contract, where the first digital signal includes a resource deduction quota corresponding to a code set in the smart contract. The first logic circuit reads the first resource balance from the special purpose register. The first logic circuit compares, using the comparator, the first resource balance with the resource deduction quota. In response to the first resource balance being greater than or equal to the resource deduction quota, the first logic circuit subtracts, using the adder, the resource deduction quota from the first resource balance to obtain a second resource balance. The first logic circuit stores the second resource balance in the special purpose register.

Systems and methods for controlling an automated electronic networked central clearinghouse for clearing and reversing reversible exchanges of digital assets are disclosed. Exemplary implementations may: execute an instance of a game; receive an exchange request that indicates a first user offers a first digital asset for a reversible exchange on a fiat-currency-based online exchange platform; access a decentralized database to obtain asset-specific distribution rights for the first digital asset; generate publication information of the first digital asset for publication on the online exchange platform; receive exchange information regarding the reversible exchange; temporarily transferring the ownership of the first digital asset; determine whether to reverse the reversible exchange, and either (i) transfer the ownership of the first digital asset to the first user, or (ii) clear the reversible exchange by non-temporarily transferring the ownership to the exchanging user, and by distributing benefits in accordance with the asset-specific distribution rights.
