Abstract: Systems and methods for verifying the presence of an attendee in an education session include providing, by a computer hardware processor, information for a codified sound to a leader of the education session, where the leader is located in a substantially enclosed space in which the education session is held. The codified sound represents a leader code. The codified sound is emitted from a first device associated with the leader. A sound signal is received by a second device associated with the attendee. An attendee code is determined from the sound signal received by the second device. The system, such as using the computer hardware processor or the second device, determines whether the attendee code matches the leader code.

Abstract: Methods include receiving location data of a location associated with a meeting, and receiving check-in information from a member's device associated with a member in an audience. The meeting has a leader. A geo-fence is set, based on the location associated with the meeting. The member's device is determined whether it is within the geo-fence using at least one of (a) using a location sensor disposed within the member's device; and (b) identifying a locatable device that has a known location and that is connected to or nearby the member's device. Feedback from a plurality of devices associated with a group of members of the audience is collected, each one of the plurality of devices having its location determined as to whether it is within the geo-fence using at least one of (a) or (b) in conjunction with the collecting of feedback. The feedback is sent to the leader's device.
