Abstract: Digital or “smart” contracts execute in a blockchain environment. Any entity (whether public or private) may specify a digital contract via a contract identifier in a blockchain. Because there may be many digital contracts offered as virtual services, the contract identifier uniquely identifies a particular digital contract offered by a virtual machine, vendor or supplier. The blockchain is thus not burdened with the programming code that is required to execute the digital contract. The blockchain need only include or specify the contract identifier (and perhaps one or more contractual parameters), thus greatly simplifying the blockchain and reducing its size (in bytes) and processing requirements.

Abstract: A system for payment based on a store's intranet, a mobile terminal including a payment function based on a store's intranet, a method for providing a payment service based on a store's intranet, and a program for performing the same are provided. The method includes providing, by a store client, a payment page in a store depending on a request of a user client, receiving, by the store client, a virtual code and order information which are input to the payment page, and transmitting, by the store client, the virtual code and the order information to a payment service server over the Internet.

Abstract: Systems and methods for transferring between accounts in the absence of sensitive information needed to perform a direct transfer between accounts are described herein. In an embodiment, an intermediary system receives a request to perform a digital electronic transfer of an item from a first online account to a second online account through the intermediary system, wherein the intermediary system does not have access to the sensitive information for either the first online account or the second online account.

Abstract: A method of a payment for an Internet of Things (IoT) device is provided. The method includes steps of: a payment supporting server (a) on condition that the payment supporting server has registered certificates of the IoT device, a service providing device, and a digital wallet in a first blockchain, manages their transaction IDs, has registered a representative hash value in a second blockchain, manages their transaction IDs, and manages link information between the IoT device and the digital wallet, confirming validity of a billing transaction, and (b) acquiring identification information on the digital wallet; and (c) paying the billing detail using the digital wallet, registering its payment result in the first blockchain, registering in the second blockchain, if one anchoring condition is satisfied, a first representative hash value, and transmitting the payment result to the service providing device, the IoT device, and the digital wallet.

Abstract: In a method for activating account-variable transaction cards having private and public card encryption keys stored therein, private and public personal keys are associated with an account and transmitted to an account holder device. A request for activation of an account-variable transaction card is received by a central processor from the user device. The request includes information encrypted using at least the private personal key and the private card key. The central processor associates an account function with the account-variable transaction card and initiates via a first node in a distributed consensus network, an account blockchain associated with the account and the account-variable transaction card.

Abstract: Systems and methods for P2P transaction functionality include payment collection from a third party source. A system includes at least one processor and a storage medium storing instructions that, when executed by the one or more processors, cause the at least one processor to perform operations including receiving transaction information from a vendor where a card was used and analyzing the transaction information. The operations also include sending one or more requests for repayment to one or more P2P service systems, receiving repayment information, regarding one or more repayments, from the one or more P2P service systems and, based on the repayment information, applying the one or more repayments to the transaction performed on the card.

Abstract: Proposed are a highly reliable automatic transaction device and a control method thereof. Specifically provided is an automatic transaction device, and a control method thereof, including a main body control unit which generates first withdraw transaction data including amount information as information related to an amount in a withdraw transaction and a withdraw command for instructing a withdraw of a paper currency based on the first withdraw transaction data, a paper currency processing unit which receives the withdraw command and pays out the paper currency, and a first device which is a device that is different from the paper currency processing unit and which determines a feasibility of a withdraw based on the first withdraw transaction data sent from the main body control unit. When the first device determines that the withdraw is possible, the first device generates withdraw credit information with security that is higher than the withdraw command based on the first withdraw transaction data.

Abstract: A system and method for verifying account ownership using verified deposits. An ACH verification platform may recognize or detect a verification process involving microdeposits. A verification platform may receive and store user login, initiate the deposits, and monitor the user's account to verify that posting of the deposits was successful. In embodiments, a dedicated web form or portal may be provided for receiving verification information.
