Abstract
A method for using electronic product identification devices to track product sales and enable sales transactions to be registered in an electronic registration (ER) system without causing privacy or security concerns for the purchasers. RF-ID devices are placed on products being sold and include detailed information about the products. When the products are purchased, the detailed information is loaded into an ER database and all but a limited amount of information is removed from the RF-ID device. The limited information is sufficient to enable the detailed information to be located in the ER database by authorized individuals in connection with a return transaction or the like.
