Have you ever wondered how gambling companies that must adhere to geographical laws keep track of where their business is coming from? They rely on IP tracking, which isn’t very new technology, but as mobile devices continue to grow in popularity among online gamblers, companies will need to figure out the best way to track business from those customers.

Enter Locaid, a company which has just developed a new mobile tracking service that banks and companies can use. Elements of online gambling may be legal in Nevada, but even mobile users are required by law to broadcasting their signals from within the state’s borders. Locaid’s technology ensures that banks, casinos and gambling operators know from where their customers are using their services. If an IP address is revealed to be outside the law, they simply turn it off to that address.

VentureBeat has the full technical rundown of the new Locaid IP Location utility:

Locaid IP Location determines the physical location of web site visitors anywhere in the world using an IP address of the device that initiates an internet session. That address reveals data about the connection originator (such as latitude/longitude, state, zip code, and network information). If it turns up something suspicious, it needs more verification to properly identify the user. Mobile location supplements this verification effort, resulting in multisource location verification. The company makes its technology available to customers through a single applications programming interface for developers.

Locaid is a San Francisco-based company founded in 2009. Seven of the top 10 banks us Locaid, which has data on approximately 350 million devices.
