South Korean tech giant Naver and fintech firm Toss are embroiled in a two-pronged dispute, industry sources revealed on Wednesday. Naver is seeking a police investigation into Toss's reward search campaigns, while Toss is preparing to file an antitrust complaint regarding access to Naver's merchant platform. The initial disagreement over whether Toss distorted Naver's search results has now spread to the offline payment market, centering on access to data and services between consumers and local merchants.
