Methods and systems for verifying compatibility of components of an electronic system are disclosed. The method includes irradiating a first and second components presumably associated with the electronic system, with XRF exciting radiation, and in response thereto, detecting one or more XRF response signals indicative of first and second XRF signatures, emitted from the first and second components. Then the first and second XRF signatures are processed to determine whether they are associated with respectively a first and second XRF marking compositions on the first and second components, and the compatibility of the first and second components to the electronic system is determined/verified based on the correspondence between the first and a second XRF signatures. Electronic systems are also disclosed including at least a first and a second electronic components respectively having the first and second XRF marking compositions that enable verification of compatibility of the components.
