Abstract: A user scans a payment card while setting up an account on a merchant's website, or while completing a check out to purchase an item or service for the first time. The subject system stores signals from the card scan (e.g., device ID, verified card, location, last time scanned and used, etc.). The next time a transaction is requested for the card at another merchant, the subject system can reference the last data it has on the card. If the transaction is being requested from the same device or a reasonably close physical location within a reasonable timeframe, the subject system can be highly confident that this is a legitimate transaction, without requiring the customer to scan their payment card again.

Abstract: Methods and apparatus related to identifying a video for completing a task and determining a plurality of video segments of the identified video based on one or more attributes of the task. A task and a plurality of how-to videos related to the task may be identified. A how-to video may be selected and a plurality of video segments of the selected how-to video may be determined. One or more video segments may be associated with one or more task attributes that relate to performing the task. The selected video may be provided to a user and segmented, indexed, and/or annotated based on the associated video segments. In some implementations a given object utilized in performing the task may be identified and one or more video segments corresponding to the given object may be identified and/or provided to the user.

Abstract: Methods and apparatus related to providing steps for completing a task based on analysis of multiple sources. A how-to query related to performing a task and a plurality of sources related to the how-to query may be identified. A set of steps related to performing the task may be determined based on analysis of the plurality of sources that are related to the how-to query, optionally including determining a confidence measure for the plurality of sources. The set of steps may be associated with the how-to query in a database. The set of steps may be provided to a user in response to the how-to query submitted by the user. In some implementations the analysis of the plurality of sources that are related to the how-to query may include comparing components of different sets of steps and identifying the common elements to determine a set of steps.

Abstract: The subject matter of this specification can be implemented in, among other things, a method that includes providing a mid state, a fullscreen state, and a miniplayer state of a touchscreen user interface for presentation on a touchscreen device. The mid state presents a first video from a queue of videos and portions of a previous video or a next video from the queue of the videos. The fullscreen state expands the first video to fit the touchscreen user interface without presentation of the portions of the previous video or the next video. The miniplayer state shrinks the first video to fit a list of videos for a user account within the touchscreen user interface.
