I'm not 100% but I believe that they have a partnership with the retailers in their network and they get a referral fee from them for each receipt scanned. I would also imagine that the actual data of what you the consumer is actually purchasing can be valuable also. For instance if Kellogg learned that 870,000 people are buying a certain type of cereal that the competition sells and they don't, id imagine that would be important to know! Hopefully that answers your question! God bless
