Abstract
CheckInShop is an app that employs sensors to capture the user preferences in physical stores and provide either micro-location marketing or product recommendations. By utilizing iBeacon technology and with the exploitation of a mobile app, we keep track of customer's preferences in physical stores. Then, based on the time that a product is viewed by a customer and his micro-location inside the store, we send to him either product offers or recommendations of similar products to the ones he is looking at. These recommendations are accurate because they are provided at the right time and in the right place. A video that demonstrates our system can be found in the following link: https://www.youtube.com/watch?v=Z99IMCHowAA
