Estimote creates small, wireless sensors that use Bluetooth low energy (BLE) to detect the location of nearby smartphones and communicate with them using an API they’ve developed to make it easy for developers to add micro-location features to their mobile apps.

Using the platform, developers and retailers can use the analytics collected from multiple sensors in a store to optimize product placement, provide indoor navigation, engage in proximity marketing, add automatic check-ins or even do contactless payments.
