Methods for location of persons using beaconing sequences

A method implemented in a server for providing a beaconing sequence for display on an identifiable first mobile device and an identifiable second mobile device in a geographic area so a first user of the first mobile device and a second user of the second mobile device can locate each other, comprising:

• receiving a request from the second mobile device;
• reading the request;
• reading the location of the first and second mobile devices;
• reading a beacon history table in response to the request read;
• in response to the reading, determining if there are recent beacon sequences used in the geographic area;
• calculating a beacon sequence from reading a preference of the first user;
• adding the beacon sequence to the beacon history table;
• and
• sending the beacon sequence for display on the first mobile device and the second mobile device, wherein the displayed beacon sequence is conspicuous and can be seen by the first user and the second user in the geographic area so that the first user of the first mobile device and the second user of the second mobile device can locate each other.
