Abstract: A computer-implemented method includes detecting a communication session established between a first computing device of a first user and a second computing device of a second user; generating session identification information for the communication session; detecting a triggering condition during the communication session to verify an identity of the first user; causing the second computing device to instruct the first user to interact a smart transaction card with the first computing device such that a one-time data item is transmitted from the smart transaction card to an application executing on the first computing device, the one-time data item dynamically generated by the smart transaction card, where the first user is authenticated via the application based at least in part on the level of authentication and the one-time data item; generating a verification token for the communication session, the authentication result stored in association with the session information.

Abstract: Aspects described herein relate to methods, systems, and apparatuses that track the availability of items from multiple vendors based on website browsing records from multiple users, and provide alerts to users when an out-of-stock item becomes available.

Abstract: Aspects described herein relate to methods, systems, and apparatuses that infer which items were purchased in a transaction based on correlating a transaction record for the purchase, such as credit card receipt, with browsing records received from multiple users of vendor websites that identify individual costs of items.
