In some implementations, a transaction card may receive transaction data from a transaction terminal based on initiation of a transaction with the transaction terminal; generate a tokenized primary account number, for use with the transaction, based on the transaction data and an actual primary account number of the transaction card; and transmit the tokenized primary account number to the transaction terminal for processing the transaction.

Methods and systems of managing payment cards are disclosed. A financial institution computing system includes a token database storing a plurality of tokens and token information, a network interface circuit enabling the financial institution computing system to exchange information over a network; and a token management circuit. The token management circuit enables a graphical user interface on a customer device over the network that can be used to generate new token requests, re-provision token requests, and management requests. The management requests enable and disable tokens, such that transactions against a payment card account using an enabled token are completed, and transactions against the payment card account using a disabled token are denied.

A method of providing access to securely held data is provided. A user interacts with the service provider to obtain access to a service by using a device to provide a digital identifier to the service provider, without the digital identifier being made known to the user. At a later date the user wishes to retrieve securely stored data relating to their use of the service. However, because the user does not know the digital identifier, they are unable to identify themselves to the service provider using the digital identifier. The present disclosure provides a secure method for exchanging private identifiers, which allows the user to identify themselves to the service provider in order to gain access to securely stored data relating to the user's previous use of the service. The user can do this using the device on which the digital identifier is stored, or another device.

The invention provides a method and corresponding system for controlling the generation of a blockchain transaction, and/or the recipient of a transaction output. It can also be used to control and record the ownership of an asset represented on the blockchain without the need for a separate registry of ownership. The ownership and transfers thereof can be handled and recorded without the need for knowledge of the parties involved or their identities. According to one embodiment, the method comprises the steps of identifying at least one transaction (Tx) on a blockchain which comprises: an unspent transaction output (UTXO) relating to a tokenised asset associated with an asset controller; and an input which spends an output from a previous transaction that is locked by a redeem script hash. For each identified transaction (Tx), an incomplete blockchain transaction is generated comprising: a first output comprising a copy of the redeem script hash; and a second output which is modifiable such that only the asset controller is able to specify a recipient for the second output. The incomplete blockchain transaction is communicated to the controller of the asset. The incomplete blockchain transaction is incomplete in that it is missing a required cryptographic signature. Thus, payment of income relating to the asset can be re-directed by the controller to a destination of their choice.

In order to improve efficiency of an operation of a cash handling system and reduce the labor required for the operation, a POS register receives an input of a cash-out amount, and an input of a charge amount. The POS register reads a debit card ID from a debit card, and transmits a settlement request including the debit card ID and a settlement amount to a management server. Upon receiving the settlement request, the management server withdraws the settlement amount from an account, and transmits a settlement permission to the POS register. Upon receiving the settlement permission from the management server, the POS register performs charge of electronic money, and transmits a dispensing instruction for the cash-out amount to a change machine. The change machine receives the dispensing instruction and dispenses cash.

A system includes a smart table. The smart table is configured to use radio-frequency identification (RFID)-enabled chips and includes a table management device and at least one RFID sensor. A dealer scratchpad defines a scratchpad area on the smart table, and the smart table defines a plurality of player positions. The smart table is configured to detect a presence of a player at a first player position of the plurality of player positions, and receive, from the table management device, a request to cash the player out of the wagering game. The processor is configured to determine, using the at least one RFID sensor, a chip cash-out value within the scratchpad area, and receive, from a player computing device of the player, a selection of a digital wallet account accessed from the player computing device. The processor also facilitates a deposit transaction to the digital wallet account.

Systems and methods herein describe a digital wallet system. The digital wallet system identifies a first request to initiate a first transaction, receives first sensitive data corresponding to the first transaction, initiates a digital wallet based on the first sensitive data, the initiating comprising generating a first wallet item designated for completing the first transaction, stores the first wallet item in association with the generated digital wallet, and stores the digital wallet.

Example embodiments relate to performing activation techniques for contactless cards. For example, embodiments may include performing a near-field communication (NFC) exchange with a contactless card, processing a message comprising data to activate the contactless card, communicating the data to a server to activate the contactless card; and receiving a response from the server, the response to indicate whether the contactless card is successfully activated or not successfully activated.

Disclosed are methods and systems for associating payment card credentials with a companion application. In an embodiment, a consumer's mobile device processor receives an instruction to launch a companion application, displays a companion application user interface, and receives selection of an option to obtain payment card credentials from at least one wallet application. The process also includes displaying a list of payment card accounts associated with the selected wallet application for association with the companion application, receiving a selection of at least one payment card account, transmitting payment account credentials of the selected payment account to a wallet server computer, receiving a companion token representing a digitization of the selected payment card account from the wallet server computer, and associating the companion token with the companion application.

Disclosed is a method, a device, and/or a system of rapid and secure off-ledger cryptocurrency transactions through cryptographic binding of a private key to a possession token. In one embodiment, a method for rapid and secure ledger-less transfer of a quantity of cryptocurrency includes generating a public-private key pair, securely storing the private key and utilizing the public key as a public address. The method verifies a ledger transaction on a distributed ledger network associated the quantity of cryptocurrency with the public address. The method generates a possession token having a state indicated by a state indicator. The state evolves upon transfer between two computing devices. The method cryptographically associates the ledger token and the possession token through incorporation of the public address into data generating the state indicator. The possession token is transferred to a computing device over the network while retaining the private key in secure custody.
