Techniques described herein enable wireless payment reader to transition between lower-power and higher-power states while still performing cryptographic operations for securing payment data without undue latency caused by the transition between sleep and awake power states. For instance, a wireless payment reader may store information associated with cryptographic operations performed by the wireless payment reader in persistent memory of the wireless payment reader so that this information may be retained when the wireless payment reader enters a low-power, sleep state. Thus, when the wireless payment reader awakens from the low-power state, the wireless payment reader may read the cryptographic information from the local persistent memory rather than needing to request this information from a payment service.

Decreasing cryptographic-operation latency on payment readers

Methods and apparatuses for providing a permissions-aware search and knowledge management system that incorporates user suggested results, document verification, and intelligent user activity tracking across group hierarchies to improve the quality and relevance of search results are described. The permissions-aware search and knowledge management system may enable content stored across a variety of local and cloud-based data stores to be indexed, searched, and displayed to authorized users. The identification and ranking of relevant documents corresponding with a user's search query may take into account user suggested results from the user and others assigned to the same group as the user, whether the underlying content of a search result was verified by a content owner as being up-to-date, the amount of time that has passed since the underlying content was verified by the content owner, and the recent activity of the user and related group members.

Permissions-aware search with intelligent activity tracking and scoring across group hierarchies

Techniques described herein are directed to, among other things, wireless payment readers configured to transition between multiple different power states. In some instances, these power states include one or more relatively low-power states such that an overall battery life of the wireless payment readers are lengthened. Further, in some instances, a point-of-sale (POS) application operating on a POS device that wirelessly couples to an example wireless payment reader may cause the wireless payment reader to transition from one state to another, such as from a first, lower-power state to a second, higher-power state in response to the POS application determining that a payment is to be processed using the wireless payment reader.
