authorizing communication of electronic content to the respective mobile device based on the required subset of the plurality of expected attendees being present at the venue.

2. The method of claim 1 , wherein the communication signal comprises a wireless network signal received at a wireless network transceiver associated with a location of the venue.

3. The method of claim 1 , further comprising obtaining, for the respective mobile device, a global positioning system (GPS) location associated with the respective mobile device and determining that the respective mobile device is within the geographical area.

4. The method of claim 1 , further comprising:

determining a number of attendees based on a count of persons present at the venue based on an analysis of an image of the venue or audio captured at the venue;

determining whether a discrepancy exists between the number of attendees and a number of the plurality of mobile devices; and

recording the discrepancy in the attendance log in response to determining that the discrepancy exists.

5. The method of claim 1 , wherein the communication signal comprises a near-field communications (NFC) signal received at an NFC receiver associated with a location of the venue.

6. The method of claim 1 , wherein the communication signal comprises a biometric identification.

7. The method of claim 1 , wherein receiving the communication signal from the respective mobile device comprises receiving a verification signal from an application executed by the respective mobile device.

8. The method of claim 7 , wherein the verification signal comprises a venue identifier.

9. A system comprising:

at least one computing device; and

a plurality of computer instructions executable by the at least one computing device, wherein when executed, cause the at least one computing device to at least:

define a location of a meeting comprising an area within which presence of a respective mobile device from a plurality of mobile devices identifies presence at the meeting;

receive a communication signal from the respective mobile device on a particular wireless network in response to a query, the communication signal comprising an authentication of the respective mobile device based on identification information entered through a user interface on the respective mobile device;

determine that a required subset of a plurality of expected attendees is present at the meeting based on the identification information and the respective mobile device being present at the meeting; and

authorize communication of electronic content to the respective mobile device based on the required subset of the plurality of expected attendees being present at the meeting.

10. The system of claim 9 , wherein a number of attendees at the meeting is identified by obtaining at least one digital image of the location of the meeting and performing an image analysis on the at least one digital image.

11. The system of claim 10 , wherein a result of the image analysis comprises the number of attendees appearing within the at least one digital image.

12. The system of claim 11 , wherein the plurality of computer instructions are further configured to cause the computing device to at least determine whether a discrepancy exists between the number of attendees appearing within the at least one digital image and a number of the plurality of mobile devices.

13. The system of claim 9 , wherein the plurality of computer instructions are further configured to cause the computing device to at least:

create an ad-hoc network associated with the meeting;

determine, based upon the communication signal, whether the respective mobile device is connected to the ad-hoc network; and

transmit the electronic content to the respective mobile device in response to a determination that the at least one of the respective mobile device is connected to the ad-hoc network.

14. The system of claim 9 , wherein the communication signal comprises a wireless network signal at a wireless network transceiver associated with the location of the meeting.

15. The system of claim 9 , wherein the area corresponds to a geo-fence associated with the location of the meeting.

16. A non-transitory computer-readable medium having a plurality of computer instructions executable by at least one computing device wherein, when executed, cause the at least one computing device to:

define a geographical area associated with a meeting, the geographical area comprising an area within which presence of a respective mobile device from a plurality of mobile devices identifies presence at the meeting;

receive a communication signal from the respective mobile device on a particular wireless network in response to a query, the communication signal comprising an authentication of the respective mobile device based on identification information entered through a user interface on the respective mobile device;

determine that a required subset of a plurality of expected attendees is present at the meeting based on the identification information and the respective mobile device being present at the meeting; and

authorize communication of electronic content to the respective mobile device based on the required subset of the plurality of expected attendees being present at the meeting.

17. The non-transitory computer-readable medium of claim 16 , wherein the plurality of computer instructions further cause the at least one computing device to:

receive a plurality of authentications obtained in response to a plurality of requests to authenticate the respective mobile device;

compare a number of the plurality of authentications to a number of the expected attendees; and

authorize communication of the electronic content in response to a determination that the number of the plurality of authentications corresponds to the number of the expected attendees.

18. The non-transitory computer-readable medium of claim 17 , wherein the plurality of authentications comprises at least one of the following: a login, a password, a meeting code, a fingerprint, an identity certificate, a retina scan, a voiceprint, or an image.

19. The non-transitory computer-readable medium of claim 16 , wherein the communication signal is received in response to tapping the respective mobile device against an RFID reader located within the geographical area.

20. The non-transitory computer-readable medium of claim 16 , wherein the plurality of computer instructions further cause the at least one computing device determine that a location of the respective mobile device indicates that an attendee is in possession of multiple mobile devices.
