The present disclosure relates generally to a system that tracks the funding source of an amount of funds as the funds are transferred between various accounts or balances of various components of the system.

A method for distributing credentials to a linked electronic wallet includes: storing a plurality of account profiles, each including data related to a transaction account including an associated account number, account identifier, and device identifier; storing a linked profile, the profile including data related to a linked transaction account including a primary account number, linked identifier, plurality of account identifiers, and account balance; receiving a linking request, the request including a specific account identifier and the linked identifier; identifying a specific account profile that includes the specific account identifier; updating the linked profile to include the specific account identifier in the included plurality of account identifiers; and electronically transmitting a data signal superimposed with payment credentials associated with the linked transaction account that includes at least the primary account number to a mobile communication device associated with the device identifier included in the identified specific account profile.

A settlement system with higher security which replaces a settlement system using credit cards is provided. The settlement system has a user terminal, a settlement device, and a settlement terminal. First, a user ID, a password, and upper limit amount information identifying an amount are inputted in a user terminal 100 (S912), and sent to the settlement device (S913). The settlement device performs credit determination (S922), generates temporary permission information if credit is possible (S923), and sends the temporary permission information to the user terminal (S924). The user terminal generates a one-time password (S915). The one-time password is inputted to the settlement terminal (S931). If the one-time password sent from the settlement terminal to the settlement device is identical to the one-time password created in the settlement device, the settlement device allows a user's payment (S928).

Provided in the present invention is a method comprising steps of: (a) confirming validity of a currency issuing transaction and a currency issuer when the currency issuing transaction including (i) a specific unique nonce, (ii) a receiver of the currency, (iii) issued amount of the currency, (iv) a public key of the currency issuer, and (v) a signature value of the currency issuer signing the (i), (ii), (iii), and (iv) with a private key of the currency issuer is obtained, and if valid, registering the currency issuing transaction on a private BCDB, wherein registering includes updating a balance database by referencing amount of change in balance due to the issued amount of the currency, included in the currency issuing transaction; and (b) registering, on the public BCDB, a specific representative hash value generated by calculating an associated hash value matching the specific hash value, when a specific condition is satisfied.

A method for facilitating a transaction with a one-time number includes: receiving a first transaction request, wherein the first transaction request includes a plurality of data elements including at least a first data element configured to store a zero transaction amount and a second data element configured to store a primary account number; parsing the primary account number stored in the second data element included in the received first transaction request; generating a one-time value, wherein the one-time value includes a predetermined number of digits and a subset of the predetermined number of digits is a reference to the processing server; storing a data entry comprised of at least the parsed primary account number and the generated one-time value; and transmitting the generated one-time value in response to the received first transaction request.

Systems and methods are provided for pairing an electronic wallet for a consumer with a service provider. One exemplary method includes receiving, by a computing device, a request to pair the electronic wallet with the service provider where the electronic wallet is associated with an account and where the account is associated with a user, and requesting, by the computing device, consent from the user to pair the electronic wallet with the service provider. The method also includes generating, by the computing device, a pairing token for the wallet application and the service provider upon consent from the user, and storing the pairing token in association with the wallet application, whereby the service provider is permitted to use the pairing token in a subsequent network transaction involving an entity associated with the service provider and the wallet application, regardless of whether the wallet application is separately paired with the entity.

A prepaid spending card for the storage of funds, the prepaid spending card comprising a single primary account number. The prepaid spending card further comprises a first purse identified by a first pseudo DDA, the first purse authorized to received funds from any available funding source, and a second purse identified by a second pseudo DDA, the second purse authorized to send and receive funds only from restricted sources. The first pseudo DDA is used to route incoming funds to the first purse and the second pseudo DDA is used to route incoming funds to the second purse. Moreover, the first purse receives funds from any available funding source and the second purse receives from restricted funding sources.

Systems and methods that facilitate performing multiple transactions at once using a vehicle based wallet are disclosed herein. The vehicle based wallet can link to a plurality of mobile wallets and perform singular transactions with ATMs and POS machines, the singular transactions being a group transaction associated with one or more of the mobile wallets.

A method and system for facilitating digital wallet based payment card transactions is provided. A server system associated with a payment network receives payment card information provided by a user to an online merchant in relation to online purchase transaction. The payment card information is associated with user consent to add a corresponding payment card to a digital wallet account. The server system creates a digital wallet account and adds the payment card to the digital wallet account if no record of the digital wallet account for the user exists at the server system. The server system adds the payment card to the digital wallet account using the payment card information if a record of the digital wallet account for the user exists at the server system. The server system facilitates processing of payment for the online purchase transaction based on the payment card information associated with the payment card.

A method for guaranteeing a blockchain transaction includes: storing account profiles, each related to a transaction account including a current balance and identification data; receiving a blockchain transaction request including a sending identifier, receiving identifier, and blockchain currency amount; transferring an alternative currency amount based on the blockchain currency amount from a first account profile including the sending identifier to a second account profile including the receiving and sending identifiers; restricting access to the current balance in the second account profile from the first account; receiving a confirmation of a blockchain transaction within a predetermined period of time; and transferring, from the second account profile, the alternative currency amount to the first account profile if the confirmation is received within the predetermined period of time, or to a third account profile including the receiving identifier if the confirmation is not received within the predetermined period of time.
