The art market depends on trust, yet traditional provenance records are fragmented, incomplete, and vulnerable to loss or forgery. NFC tags and digital certificates create a secure, tap-to-verify link between a physical artwork and its ownership history. This guide explains how galleries, オークションハウス, コレクター, 美術館, insurers, and art logistics providers can use NFC authentication to verify authenticity, trace the provenance chain, simplify condition reporting, and protect the long-term value of paintings, sculptures, and collectibles. Learn where to place tags, what to include in a digital certificate, and how to build an ecosystem-wide verification workflow.
