Four Square allows you to register your business/premises on their social network.
Customers can leave reviews. There’s an accelerating trend for people to use ‘crowd sourcing’ and so this is gaining popularity.
Four Square enables you to check-in to a location. Points and badges are awarded for every check-in and you can compete on leader boards with your friends. Some businesses have smartly made use of the offers feature. This lets businesses set up offers for Four Square users who check in, i.e. 10% off the cost of a meal.
