The Foursquare Package addon allows you to show information from Foursquare on your website. In addition, it uses vCard microformatting for the address and contact information.

It has many configuration options, including:

• Background and Text Colors to match your theme
• Which sections to show (Mayor, Photos, Tips)
• Which order to show the sections

It requires a Foursquare Client ID and Secret, which you can get at https://foursquare.com/oauth/register
