1. A verification system comprising:

  • a memory storing an identifier and an encryption key;

    a wireless broadcast element;

    a timing device configured to generate a time value;

    a processing circuit electronically coupled to the memory, the timing device, and the wireless broadcast element, the processing circuit configured to periodically generate a verification code from a transformation of the identifier, the encryption key, and the time value generated by the timing device, wherein the wireless broadcast element is configured to broadcast the verification code, a plurality of mobile devices receiving the broadcast verification code and sending the verification code to a server; and

    the server, wherein the server is configured to incorporate a time offset between a time value of a server clock and the time value of the timing device to synchronize the server with the wireless broadcast element, wherein the server is configured to compare a received verification code to expected server-generated verification codes corresponding to time values within a designated time window, wherein the server is configured to authenticate one or more of the plurality of mobile devices based on whether the received verification code matches one or more expected server-generated verification codes corresponding to time values within the designated time window.
