Facebook has launced his new application called Facebook Places. It’s similar to Foursquare, where you can check-in in the places that you visited and share your locations with your family and friends through Facebook in real time from your mobile device.

When you check in, you can also tag friends who are with you, just as you can tag a friend in a status update or photo. You can post an update along with your check-in to tell people more about what you are doing.

With Facebook Places, you are in control of what you share and the people you share with. You choose whether or not to share your location when you check in at a place. You also have the choice to set more restrictive customized settings.

How to Disable Facebook Places :

1. Log in to Facebook. From Account choose Privacy Setting, then click Customize Settings.
2. Scroll down and find Places I check in to. From here, you can set how you want it to be visible in your Facebook account. Choosing Only Me will disable or it will not sharing any location to anyone.
   Include me in “People Here Now” after I check in will let people know you’re at a particular location via the location’s page or in a search for people near you. Uncheck “Enable” if you don’t want this.
   
3. Any friend could potentially check you in anywhere. You don’t actually have to be there. If you don’t want your friends to check you into Places and share your current location, scroll down to Friends can check me in to Places and set to Disable.
   

So far, Facebook Places only available for US users only with the new version of the Facebook iPhone Application or are accessing the touch.facebook.com. And will become available to everyone over the next few days.
