I'm trying to get some information for a application we would like to develop for our business. We run a chain of stores (approximately 20) and would like to give our customers reward points when they check-in to our store location. We would also like to display that information our company site eg. "Client X has checked in Location Y". I was wondering if anyone can point me to any API(s) or solutions that may be able to achieve something along these lines? I was looking at the foursquare API, is this a viable option? or is there any other recommendations?
Thank you
As Fahri pointed you can use 4sq API, but nowadays all socials integrate geolocation. You can share your position also using Facebook and Twitter. I will suggest to use the last two, because they has integrated authentication, and API since iOS6, probably they are also more used than 4SQ.
