User interface technology related to a composite file or page (e.g., Webpage) including information from various entities (e.g., physical product providers) may be improved by providing a composite score (determined from one or more constituent parts) for each of the entities in a way that occupies less space than would otherwise been needed if constituent scores of each of the entities were provided. Such example embodiments may also improve user interface technology by reducing the cognitive load on a user reviewing information presented on a composite Webpage. This, in turn, reduces “friction” related to using and interacting with such a composite Webpage. Such example embodiments may also improve user interface technology by presenting information from various different entities in a uniform manner, with a consistent look and feel.

Embodiments of the present disclosure relate to administration of an electronic survey to collect perception ratings for an event. For example, an electronic survey system provides a perception survey question to a respondent client device for an event (e.g., a digital media event or a live user experience). As a user associated with the respondent client device experiences the event, the user indicates a perception rating over time for the event by interacting with a graphical input element corresponding to the perception survey question. The survey system collects perception data points indicating the perception rating of the user and associates information about the user with the perception data points. The survey system can generate response data for the perception survey question based on the perception data points. The survey system can also generate a perception data report using the user profile information.

Embodiments leverage the PCI-DSS validation of a backend transaction processing system to avoid the payment application having to meet the PCI compliance reporting requirements of the PCI-DSS. When the payment application needs to collect Sensitive Data for a transaction, the payment application makes a request to the payment library, which in turn requests from the backend system a secure web page including fields for the user to enter the specific Sensitive Data to be collected and typically also including a public encryption key generated specifically for the secure web page. The payment library causes the secure web page to be rendered, thereby allowing the user to enter the required information. Upon completion of such data entry, the data entered via the secure web page is pushed back through the payment library to the backend system for processing. The backend system can decrypt the encrypted data using the private key associated with the public/private encryption key pair.

Systems and methods are provided for accessing records using derivative locators. An open financial transaction may be initiated by a consumer at a merchant. The merchant may provide information relating to the transaction, which may include information about the consumer's device, to a repository. The merchant may provide transaction information to the acquiring bank, which may provide transaction to the global financial network, which may provide transaction information to an issuing bank. One or more requesting party (e.g., one or more of the acquiring bank, global financial network, or issuing bank) may formulate a derivative locator based on the transaction information received. The derivative locator may function as an index through which records in the repository may be accessed by the requesting party. A time comparison may be made in assisting with accessing the correct record in the repository. The requesting party may determine whether to accept or decline the transaction, optionally with the aid of the information accessed from the repository.

Provided herein are techniques for rescuing a commercial transaction identified as suspect, possibly based on suspicion of fraud or due to the risk associated with the commercial transaction. Various implementations include systems and methods that can rescue a purchase transaction involving a purchasing party (hereafter, a “purchaser”) and a selling party (hereafter, a merchant”). The item or items being purchased in the purchase transaction can include goods, a services, or property interests (e.g., real, intellectual, or otherwise). Particular implementations can facilitate the rescuing of a purchase transaction that has been declined, canceled or suspended (e.g., pending further review) by an involved party (e.g., the selling party) based on that party's concern (e.g., fraud or high risk) with respect to the purchase transaction.

Embodiments described herein disclose methods and systems for authorizing a payment card transaction using dynamic codes. The system can receive a request for authorization of a transaction using the payment card. The request can identify a verification code associated with the payment card and an identifier of the payment card, and the payment card can have an associated dynamic code accessible to a user via a channel. The verification code can be compared with a value of the dynamic code at the time of the transaction. The system can determine whether the user of the payment card accessed the channel within a time period prior to receiving the request for authorization. In response to the verification code matching the dynamic code at the time of the transaction and determining that the user accessed the channel within the time period prior to receiving the request, the system can authorize the transaction.
