Proximity-enable your mobile app by installing the PTM Proximity Engine SDK.
The engine uses Bluetooth to discover devices within up to 250 feet and to collect their ProxToMe ID numbers.
The engine sends detected ID numbers to the server and verifies they belong to the ProxToMe database. If yes, it establishes a communication across the wide area network otherwise rejects them.
Once connected, devices can send and receive data across the wide area network. Actions and events then depend on the service built on top of the engine.
