In some embodiments, apparatuses and methods are provided herein including: at least one user product with at least one passive sensor; at least one network reader configured to expose the user product to energy and measure reflections of the energy from the at least one passive sensor; and a control circuit operably coupled to the network reader. The control circuit configured to receive an initial signal reading of the at least one passive sensor from the network reader; save the initial signal reading in a user profile in a profile database; receive a reading of one or more reflections of the energy from the at least one passive sensor; and compare the reading of the one or more reflections with one or more profile readings associated with the at least one user product and the at least one passive sensor to determine a degree of wear of the user product.
