By using RFID chip it is possible to establish good marketing relationship between customer and business (Shops, restaurants, cafes, clubs etc.). One of the scenarios of this could be the following case:Every high street shops can give RFID chips to its customers, which will be used as an ID. Customers can attach this chip inside their mobile phones (why mobile phone: because according to statistics people always carry their mobile phones with them). When customer (who has RFID chip) will be nearby a shop (in range of 5/15 meters, can be adjusted manually) shop will detect RFID chip, then identifies user, after this checks in database recommended goods for selected customer and sends news and offers to customers mobile phone as SMS (only if user has subscribed this service).By this way user always knows that his/her favourite shop is nearby and it have something new for him/her. This way marketing relationship will be improved between customer and businesses.*Note: one RFID chip can be used by many shops, restaurants, cafes, etc.
