Hi, i am in the process of designing a prototype for an app / project that i am working on.
One part of the app relies heavily on the user's location. They will need to check into various hotels via the app, however they must only be allowed check in if they are physically in the building.
I think this will be impossible to do for two reasons:
01 - you can't get pin point accuracy with location services
02 - a hotel might not have good reception and therefore the user might not be able to pick up their exact location
Based on the above, what is the closest / smallest radius that the app should set. For example, if you are within 20 metres of hotel, you can checkin?
Any other advice on this would be greatly appreciated.
