You are welcome to check out a new version of our mashup Places from Facebook.
Lets you search for known places, show them on the map, copy locations to mobile, check-in anywhere as well as prepare customized mobile web pages for check-in
You can directly pass the following parameters to the basic URL:
lat - latitude
lng - longitude
q - query for search
For example, Facebook in London
With customized check-ins service places owners can create own pages for check-ins. Created mobile page could be presented for users via some link on any web site (like 'Check-in here') or via QR-code (for real visitors). Customized check-in page lets creators provide own content for all steps in the check-in procedure (what should be posted on customer’s wall, what should be provided as a response etc.). You can see how to create customized check-in page here.
P.S. and here you can see Google Places
