We are working on new features that take this concept further, with badges that only the cashier sees.
Merchants using Fan Clubs have requested the ability to give special perks and services to customers based on social criteria, not just how often they visit.
The first set of badges show whether or not a customer is an Influencer, Promoter or Frequent Shopper. Merchants can choose to adapt their services and promotions based on these criteria. The challenge is to find simple and fast ways to adapt the purchase experience without much effort. Kind of like the Silver, Gold and Platinum card experience used by airlines, but adapted to the needs of local businesses.
