# Scan app devices
One of the services Eventication can deliver is scan devices. Find out more detailled information about these devices [here](https://docs.eventication.com/event/misc/4g-scan-devices).
## List
This page displays a list of the rented devices. If you have currently rented devices the top of the page will show a map followed by the list. This page will auto refresh depending on the heartbeats the devices send to Eventication every 30 seconds.
This will update:
* The battery status percentage
* If the device is charging 
or not 
* If the Eventication app is at the foreground or not
* The current logged in moderator, or the last logged in moderator
## Map
This page is just an enlarged version of the map in the previous section.
## Usage
Here you can find an overview of the usage of the device. For scan app devices you will see a table that has the different devices in the rows and the different event days in the columns. Per day per device you get a number of actions a device has done (given a meal, checked somebody into a zone, checked into a parking, ...).
At the bottom and at the right side of the page you can find cumulative information about a single device or a single day. In the right bottom corner you can find the total number of actions.

Please note that the usage numbers are calculated once per hour.
