There's always risk involved in sharing personal information. Loyalty rewards are just useful in checking the customers' buying patterns. To the customers, i think it's more of a threat rather than a reward because these companies holding the customers' personal information can possibly create a secret "back door" to sell or divulge these information to 3rd parties, example for ethnic profiling, or other reasons we do not know.
