Aspects discussed herein may relate to techniques for authenticating a user using transaction-based authentication questions. Hold transactions conducted using a financial account may be identified and verified. The hold transactions may be transactions that do not post to the financial account, and therefore are not provided on any financial account statement. The transaction-based authentication questions may be generated based on the identified and verified hold transactions. The user may be authenticated based on responses by the user to the transaction-based authentication questions. Malicious actors that gain access to financial account statements are unlikely to answer the transaction-based authentication questions correctly as they are based on financial transaction data that is not provided on the financial account statements.

Aspects described herein may relate to techniques for detecting login activity to a financial account during a knowledge-based authentication process. The login activity may be related to access to an online interface for the financial account. The detection of login activity during the authentication process my indicate that the integrity of the authentication process is compromised as login access may provide an individual with transaction data that may be used to answer transaction-based authentication questions. As a result of detecting login activity, an alternative authentication process may be initiated or an authentication request related to the financial account may be denied.

Systems and methods for alternative payment mechanism payments using ultra-wideband radio technology are disclosed. A method may include a payment terminal computer program executed by a payment terminal selecting a customer electronic device that is conducting the payment transaction with the payment terminal; communicating, via a payment terminal UWB radio to the selected customer electronic device, payment transaction details for the payment transaction comprising a merchant identifier and a transaction amount; receiving, from the selected customer electronic device via the payment terminal UWB radio, an APM payment message for an APM payment provider; communicating the APM payment message to the APM payment provider, wherein the APM payment provider is configured to decision the transaction based on the APM payment message; and receiving, from the APM payment provider, a payment confirmation for the payment transaction.

One embodiment of the present disclosure provides a system and associated processes for sharing cardholder data (CHD) between a merchant that utilizes tokenization and a second merchant that may or may not utilize tokenization. In one embodiment, the merchant, or an employee of the merchant, can use the system and associated processes to reacquire CHD from a tokenization provider system. In one embodiment, the merchant identifies to the tokenization provider system a desire to share CHD, which is associated with a token, with a second merchant. The merchant and/or the tokenization provider system can then invite the second merchant to register with the tokenization provider system. Once registered with the tokenization provider system, the second merchant can access any CHD that the merchant associated with the second merchant.

Various embodiments, relate to a system of lockers including a plurality of tracks and a plurality of walls. At least two of the plurality of walls slidably coupled to at least two of the plurality of tracks. Four of the plurality of walls form four sides of a locker cavity. The system also includes a plurality of doors. Each of the plurality of doors are oriented perpendicular to the plurality of the walls. A first door of the plurality of doors is coupleable to a second door of the plurality of doors so as to form a third door, and at least one of the plurality of doors form one side of the locker cavity. The system also includes a back wall, which forms one side of the locker cavity. The system further includes a lock for securing positions of the plurality of walls and of the plurality of doors.

Systems and processes are disclosed for providing customized user interfaces for facilitating personal payment transactions. In some embodiments, disclosed embodiments may generate a dynamic and customized interface for effecting the personal payment transaction by, for example, providing one or more options for the payer to fund the payment. The disclosed embodiments may provide an interface that includes one or more suggested recipients for identifying the payee associated with the payment transaction. The disclosed embodiments may also provide an interface that includes one or more routing options to route the payment. The disclosed embodiments may also provide an interface that provides one or more communication channel options for parties associated with the personal payment transaction to communicate.

A system includes a server and merchant device. The server receives product information for a product scanned by a mobile device. The server stores the product information for the product in a digital cart. The server receives a transaction request from the mobile device, determines that the product is associated with a validation requirement, and transmits a validation request to the merchant device. The server receives, from the merchant device, an indication that the validation requirement is satisfied, processes a transaction, and transmits, to the merchant device, an indication that the transaction is complete. The merchant device receives the validation request, determines that the validation requirement is satisfied, and transmits the indication that the validation requirement is satisfied to the server. The merchant device receives, from the server, the indication that the transaction is complete and displays the indication that the transaction on the display.

A method of registering a user with a third-party service using an identity verification process, comprising receiving configuration data from the third-party service. The configuration data comprises a user number associated with the user of the third-party service; and application data associated with the third-party service. The configuration data is used to generate a uniform resource identifier, URI, for an application associated with the identity verification process, distributing the URI to a device associated with the user; and receiving a notification from the device indicating that the user has accessed the URI. In response to receiving the notification, at least part of the configuration data is sent to configure the application on the device in order for the user to perform the identity verification process, associated with the third-party service, to register with the third-party service.

An electronic fund transfer system comprises a transaction server, a first mobile electronic device operated by a first user, and a second mobile electronic device operated by a second user. The transaction server stores user profiles, including financial account details and other personal details, for each of the first user and the second user, and further stores therein a list of first users associate with a premise. The second mobile electronic device is operable to obtain from the transaction server the list of first users associated with the premise. The second mobile electronic device is further operable by the second user to select one first user from the list and effect a transfer of funds from the second user to the selected first user. The transfer of funds from the second user to the selected first user is effected without any of the financial account details and other personal details of the first user being provided to the second user.

Techniques are provided for propagating updates to user profile information using a blockchain and for controlling access to user profile information using a blockchain. In one embodiment, a first block is added to a blockchain. The first block includes a first transaction ID that identifies a first transaction entry in the blockchain and a first version of user profile information encrypted using the first encryption key. The first transaction ID and a first decryption key that is able to decrypt information encrypted with the first encryption key is communicated to a plurality of entity computing devices that are to use the user profile information. The user profile information is updated by adding a second block to the blockchain that refers to the first transaction ID and includes a second version of the profile information encrypted using the first encryption key.
