determining, individually, whether any of the received SMS mobile originated entrance communications are authentic;

determining an originating location of each authenticated SMS mobile originated entrance communication;

correlating each authenticated SMS mobile originated entrance communication with an associated physical facility;

authorizing each user associated with each of the authenticated SMS mobile originated entrance communications to enter the associated physical facility;

receiving an exit message from each user having authorization to enter the associated physical facility, the exit message including a keyword;

validating the keyword in the exit message;

wherein when the exit message is invalid, an automated SMS message is sent advising the respective user to make another attempt; and

wherein the exit message is valid, an acknowledgement SMS exit message is sent to the respective user;

determining a time duration that each user having authorization to enter the associated physical facility spent at the associated facility; and

transmitting a mobile terminated message to each user having authorization to enter the associated physical facility.

12. The computer readable medium of claim 11 comprising instructions for:

logging an entry time of the user to the associated physical facility.

13. The computer readable medium of claim 11 comprising instructions for:

updating a checked in status with data associated with the user at the associated physical facility.

14. The computer readable medium of claim 11 comprising instructions for:

logging an exit time of the user from the associated physical facility.

15. The computer readable medium of claim 11 comprising instructions for:

updating a central jurisdiction console with data associated with the user at the associated physical facility.

16. A system, comprising:

a processor, wherein the processor,

receives plurality of SMS mobile originated entrance communications from a plurality of users, each SMS mobile originated communication associated with a particular user;

determines, individually, whether any of the received SMS mobile originated entrance communications are authentic;

determines an originating location of each authenticated SMS mobile originated entrance communication;

correlates each authenticated SMS mobile originated entrance communication with an associated physical facility;

authorizes each user associated with each of the authenticated SMS mobile originated communications to enter the associated physical facility;

receiving an exit message from each user having authorization to enter the associated physical facility, the exit message including a keyword;

validating the keyword in the exit message;

wherein when the exit message is invalid, an automated SMS message is sent advising the respective user to make another attempt; and

wherein the exit message is valid, an acknowledgement SMS exit message is sent to the respective user;

determining a time duration that each user having authorization to enter the associated physical facility spent at the associated facility;

transmitting a mobile terminated message to each user having authorization to enter the associated physical facility; and

a non-transitory memory communicably coupled to the processor, wherein the memory stores the authorization of the user to enter the associated physical facility.

17. The system of claim 16 wherein the processor,

logs an entry time of the user to the associated physical facility.

18. The system of claim 16 wherein the processor,

updates a checked in status with data associated with the user at the associated physical facility.

19. The system of claim 16 wherein the processor,

logs an exit time of the user from the associated physical location.

20. The system of claim 16 wherein the processor,

updates a central jurisdiction console with data associated with the user at the associated physical location.
