History of RFID tagging flyable parts on aircraft. I think it's a very interesting story and there are a lot of insights to be gained by looking back over the past ten years. There have been some key market drivers along the way such as AS5678 specification, and clear indications that the sector has embraced the value of high-memory RFID tagging. The programs have not just gone according to plan, they have been accelerated well beyond the original rollout plans.
