TOPGUEST lets users earn reward points for using geo check-in software at participating partners. The site is compatible with all the major geolocation apps (Foursquare, Gowalla, Google Latitude, Loopt, Twitter, and Yelp). While geolocation services are among the hottest startups around, what they’re useful for is still being worked out. By monitoring your whereabouts for checkins at its partner hotels, TOPGUEST ties geolocation-based checkins to loyalty and reward schemes.

While Tasti D-Lite has already experimented with using Foursquare as part of its loyalty program, TOPGUEST is looking to take things to the next level by creating a centralized loyalty system that converts checkins on any gelocation service into points or rewards with any participating partner.

Another notable aspect of TOPGUEST is the ease with witch users are able to sign up.
