If the user will not check out the checkin will be lost in the history of checkins.
We should be persisting the checkin and somehow check if it's still active or not.

1. Scan Trigger

save an entry only for supported providers, logo, time of the scan and the date
save an entry only for not supported providers: url, and the logo (favicon), if not there don't show, time, scan and the date time
2. Checkin Trigger
update the 'scan' entry with the actual venue, checkin time etc.
not supported providers: do nothing
3. Checkout Trigger
just add the checkout time
4. The trigger that is not triggered
if the service does a automatic checkout (eg. recover after 4hours or the owner does a checkout) then the record should be saved and update after 24 hours (show: ausgecheckt durch service)
