AI generated    Although embedding RFID chips in paper has been demonstrated , no major currency in the world currently uses it as a standard feature. For example, the Bank of England — issuer of British pound notes — says clearly that their banknotes do not have RFID or any tracking technology embedded.  There are microchips (specifically small RFID-type chips) that could be embedded into paper, including banknotes, but in practice they are rarely used (if at all), and there are serious technical, cost and privacy challenges. Here’s a breakdown of the situation. ✅ What technology exists (or has existed) for embedding chips in paper/currency-like objects A major electronics company, Hitachi, developed a micro-RFID chip (sometimes called a “µ-chip”) small enough to embed in paper, documents or banknotes. Researchers (for instance at North Dakota State University, NDSU) have demonstrated methods — such as a laser-based assembly technique (called “LEAP”) — for embeddin...
