Use Case

Paywall Enforcement

Prevent free-tier abuse and content theft

The problem

Users bypass paywalls and metered content limits by clearing cookies, using incognito mode, or switching browsers.

The solution

FingerprintIQ creates a persistent device identity that survives cookie clearing, incognito mode, and browser switching. Track content consumption per device rather than per cookie.

Code example

const result = await fiq.identify();
const articleCount = await getArticleCount(result.visitorId);

if (articleCount >= FREE_ARTICLE_LIMIT) {
  showPaywall();
} else {
  await incrementArticleCount(result.visitorId);
  showArticle();
}
