A method for tracking vibrational information for an item via an RFID tag is provided. The method includes interrogating the RFID tag at various points throughout the supply chain to obtain vibrational entries for the RFID tag. The vibrational entries are then individually compared to a set of thresholds. The sum of the one or more vibrational entries may also be compared to a different set of thresholds. A designation for the item (e.g., non-operational, potentially damaged, normal) is then assigned based on the results of the comparison.
