Enhanced mobile device beacon system

A database processing method executed on a server to retrieve and store data in one or more databases which detects attributes of a user based on information obtained from or about a user device, the database processing method comprising:

• storing user information of a plurality of users in a first database;
• storing campaign information of a plurality of campaigns in a second database;
• communicating with a beacon device, wherein the beacon device
• retrieves a first unique identifier transmitted wirelessly from the user device, wherein the user device is within a threshold distance of the beacon device;
• receiving the user information and the first identifier from the beacon device, wherein the user information populating a user profile associated with the user in the first database;
• estimating a first campaign of interest for the user based at least partly on the user information and target criteria of the first campaign, wherein the first campaign and the target criteria of the first campaign are stored in the second database;
• and
• providing the user with the first campaign.

A beacon device which detects attributes of a user device based on information obtained from or about the user device, the beacon device is configured to:

• retrieve a first unique identifier transmitted wirelessly from the user device, wherein the user device being within a threshold distance of the beacon device;
• measure the signal strength of the wireless transmission of the first unique identifier, wherein the measurement is made from one antenna connected to the beacon device;
• encrypt first unique identifier;
• and
• transmit the collected encrypted first unique identifier and signal strength to a server.
