SNS

SNS (Social Networking Service) refers to platforms where users connect and share information online, such as X (formerly Twitter), Instagram, LINE, Facebook, and TikTok. QR codes are used with SNS to bridge offline and online, for purposes such as profile access, follower growth, and campaign participation.

One SNS-QR combination encodes an account's profile URL. Business cards, store posters, and event venues display QR codes that lead to follow or friend requests. LINE has a native QR-based friend-add feature. Instagram offers QR code profile sharing.

For marketing, QR codes direct users to SNS campaign pages where following and reposting complete an entry. Dynamic QR codes allow redirecting to a regular profile page after the campaign ends, preventing wasted printed codes. Scan counts can be tracked for each flyer or poster.
