SK Telecom, along with Deutsche Telekom, introduced a mobile identification app using blockchain at 'MWC2019'. Visitors to the exhibition hall can get a virtual ID using blockchain and use it to enter the booths of both companies and experience collecting tokens and exchanging them for prizes through content experience. Combining this journey with analog design elements (Stamp, Paper, Trip, Wallet), it became an opportunity to relieve reluctance to new services and provide a friendly experience.
