A RFID method for storing products in a defined location is provided to minimize undesired combinations of stored products resulting from improper placement of the products in the storage location. RFID smart tags are associated with any products to be stored within the storage location, the smart tags containing information to identify the product they are associated with. A product profile is compiled and stored for any products to be stored within the storage location, the profile may include information on products, materials, and substances that should not be stored together or in close proximity to the profiled product. A smart tag scanner is disposed at a position relative to the storage location such that the scanner is within range of any smart tag associated with a stored product at any position within the storage location, the smart tag scanner configured to retrieve the product identification information from the smart tags. For the products identified by the scanner, the respective product profiles are use to determine if any of the identified products are improperly stored relative to any other identified product.
