Estimote provides wireless beacons and a platform that allows apps to trigger contextual actions based on a user's proximity to beacons. Beacons communicate with nearby phones to identify locations and trigger personalized notifications or payments. Estimote's SDK allows developers to integrate beacon technology into apps. Use cases include directing customers in stores, dynamic pricing based on weather, greeting VIPs at airports, and contactless payments at restaurants. Nearly 20,000 developers are using the platform across industries like retail, healthcare, transportation, and hospitality.
