To answer your question, I reached out to Amir Khoshniyati, the general manager and VP of the transponder business at Identiv, a leading provider of NFC and passive UHF RFID systems. Amir says the lifespan of a tag does not correlate to memory. “It has to do with the environment in which it is kept,” he states. “In a stable environment, an NFC tag can last for 20 years or more.” I would add that I have not heard of tags no longer working due to their age. In fact, I believe there are companies still using tags that were deployed more than 20 years ago.
