ISO/IEC 15693 (NFC-V)

ISO/IEC 15693 (NFC-V) defines the vicinity coupling standard for contactless identification cards operating at 13.56 MHz. Unlike ISO 14443's proximity range (~10 cm), ISO 15693 achieves read distances up to 1.5 meters using larger antennas and different modulation schemes. The standard is widely deployed in library management, industrial tracking, and supply chain applications. NFC Forum adopted it as the basis for Type 5 tags.
