The present disclosure presents a method for a card based transaction between a mobile terminal and a service provider system having one or several computer servers. The mobile terminal obtains a CSC from credit card/debit card. The mobile terminal obtains a data seed. The mobile terminal applies a minimal perfect hash function to the CSC as well as the data seed to generate a temporary CSC. The mobile terminal initiates a card based transaction with the service provider system utilizing the generated temporary CSC. The service provider system obtains the temporary CSC and applies a same minimal perfect hash function to the temporary CSC until a match is found between the obtained temporary CSC and one CSC stored at the service provider system. In response to a match the service provider system continues the initiated card based transaction with the mobile terminal.

The present disclosure generally relates to the use of loyalty accounts, private label payment accounts, and general payment accounts using a wearable electronic device with an electronic wallet. Various accounts are linked to the electronic device. In some examples, the electronic device is NFC-enabled. The electronic device may be used to provide loyalty account information and payment account information to a payment terminal, such as an NFC-enabled payment terminal.

A method is disclosed for conducting a transaction between a computing device and an access device. A server computer may be utilized to facilitate data exchanges between the computing device and the access device. These data exchanges may utilize high-frequency sound signals. The server computer may encrypt at least some portion of data that is then transmitted to the access device via the computing device. The server computer may verify data received from the access device prior to generating and transmitting an authorization request message for the transaction.

Various embodiments are generally directed to autofilling card data from a contactless card to a form of a computing device. An application may determine that a payment field of a form has received focus. The application may then receive encrypted data from a communications interface of a contactless card associated with an account. The application may then receive, from a server, verification of the encrypted data. The application may then receive, from the server, an encrypted account number associated with the account, and decrypt the encrypted account number to yield the account number. An autofill service of an operating system (OS) executing on the processor circuit, may then autofill the account number to the payment field of the form.

A method and apparatus for processing a transaction between a merchant and a customer of the merchant are described. The method may include generating, at an ingress server, an initial transaction message by generating a deterministic identifier for a card used in the transaction from card data received for the transaction and encrypting the received card data. The method may also include providing the initial transaction message from the ingress server to a payment server. Furthermore, the method may include updating, by the payment server in response to an authorization of the transaction determined based at least in part on the deterministic identifier for the card, the initial transaction message with authorization data, and providing the updated initial transaction message from the payment server to an egress server. The method may also include communicating a final transaction message to an authorization system for processing the transaction between the merchant and the customer based on the card data.

Systems, methods, and computer-readable media for providing accurate images of cards. An application executing on a mobile device may receive authentication credentials for an account, determine a card associated with the account, and determine a card manufacturer identifier (CMID) of the card. The application may receive, from a digital asset management system based on the CMID, a plurality of metadata attributes of the card and one or more images of the card. The application may determine, based on the metadata attributes and attributes of the mobile device, a first orientation of the card to enable near-field communication (NFC) data transfer between the card and the mobile device. The application may select a first image of the card. The application may generate a graphical user interface (GUI) including the first image and an indication specifying to tap the card to the mobile device according to the first orientation.

Embodiments of systems and methods for fraud prevention in an online distribution network are disclosed. In certain embodiments, service providers that provide forms in association with merchant's web sites for submission of transactions may implement pro-active threat detection based on an aggregate view of transactions in that distributed computer network.

This disclosure describes methods, non-transitory computer readable storage media, and systems that utilize one or more virtual cards to autofill payment information at a user client device for a payment transaction. For example, the disclosed system utilizes a reference identifier to determine a virtual card corresponding to the payment card account based on a virtual card account mapping. The disclosed system provides a stored virtual card identification number and virtual card verification data (e.g., an expiration date and a card verification value) to a user client device for autofilling the virtual card identification number and the virtual card verification data at the user client device in connection with a payment transaction. Additionally, the disclosed system processes the payment transaction in response to receiving a virtual card from a merchant system by swapping the virtual card with the payment card account when providing transaction details to a payment network.

A method for optimizing transaction authorization conversion rates includes retrieving payment transaction parameters and authorization results for a plurality of past payment transactions, generating authorization success factors for each of a plurality of payment transaction parameters based on the retrieved payment transaction parameters and authorization results, receiving, at an acquirer processor, a payment transaction from a merchant, modifying one or more parameters of the payment transaction according to the generated authorization success factors, and submitting the modified payment transaction to a financial institution for processing.

Various embodiments are directed to overlaying relevant product information in augmented reality via the use of near-field communication (NFC) and a product selection system. A user may authenticate into an application or user profile. Information about the user in the user profile may be used to determine which products are relevant to the user. Information related to the relevant products may then be displayed to the user in augmented reality, which improves at least the overall shopping and in-store experience.
