An information processing system for consumers at a store may include a plurality of radio frequency (RF) identification devices, where each RF identification device is to be temporarily associated with a respective consumer during movement about the store. At least one RF receiver device may be arranged about the store for receiving communications from the RF identification devices, and at least one consumer identity reader may be arranged about the store for reading respective identities of the consumers. An information processor may cooperate with the RF receiver device(s) and the consumer identity reader(s) for generating consumer position data of the consumers during movement about the store based upon communications from the respective REF identification devices to the at least one RF receiver device, associating the consumer position data with respective identities of the consumers, and initiating consumer-specific advertisements based upon the consumer position data and respective identities of the consumers.
