Stardust

dust-like material that can be sprayed onto wood and detected only with a hand-held device. Stardust has the potential to be applied to timber and pulp and paper products as a cheaper alternative to bar-codes, radio-frequency identification (RFID) and other tracking technologies.Stardust is applied via microscope optical markers, thus promised to be precise, hand-held and practical in-field detection devices. There are multiple markers available, they should provide instant authentication.
