Two visitors on Sept. 22 look at non-fungible tokens (NFT) of postage stamps at this year's Korea Philatelic Exhibition held at Korea Postage Stamp Museum in Seoul's Jung-gu District. The nation's first NFTs of stamps offer unique value to digital images through blockchain technology, which makes it impossible to forge or modify an NFT and allows online viewing of it.
