ISO/IEC 14443-3B (NFC-B)

ISO/IEC 14443-3B (NFC-B) defines the initialization and anti-collision mechanism for Type B contactless communication. Type B uses 10% ASK modulation with NRZ-L coding, providing better noise immunity than Type A in some environments. Type B is primarily used in electronic identity documents, ePassports, and some European banking cards. It is less common in consumer NFC tags but essential for government credential applications.
