Good Afternoon Mam,

There are lots of ways but this one is easy method. Note that even this isn't 100% accurate because if someone uses a proxy or another trick then it's a lot harder to tell where they're coming from, if at all.

Here is an easy method to get you started though:

1) Get the Geolocation via IP address (This is a cheap way. If you are serious about this then you will need to buy a Geolocation database that has all of this information in it).

2) Calculate the distance based on the latitude and longitude points.

If you are programming smart devices then they will have something in the API for obtaining the locations. For instance, GPS will give you the latitude and longitude points.
