xamoom supports all techniques to identify the user’s context – the geo position or the proximity to an object.
None of those techniques is perfect – all of them have their specific strengths and weaknesses.

|Description||Small Bluetooth transmitters with a battery broadcast constantly information. There are two different beacon types: iBeacons broadcast three IDs. If they fit to an installed app, it can react accordingly. Eddystones broadcast URLs to which the mobile Chrome browser can notify the user.||A tiny chip holds a URL stored. With the coil around the phone can give energy to the chip. Subsequently, the chip then reveals its information. The URL is opened in the mobile browser.||A two-dimensional code that contains a URL. With QR scanner apps the phone decodes the URL and opens it in the browser.||Revolving around a point on the map, a circle is drawn (a “geofence”). In this imaginary circle, an app display the certain fitting information. In mobile browser a special URL (e.g xm.gl) must be opened.|

With xamoom any combination is possible:
- Smart labels (NFC and QR)
- Smart labels with GPS geofence
- only QR code, printed in a brochure or on a product package
- iBeacon with GPS Geofence
- and much more
In addition, our flexible architecture allows us to react fast. Future technologies can be introduced quickly. Examples would be optical image recognition, handwriting recognition or LiFi (data through LED light).
