Providing a positive return user experience (RUX) is essential for enhancing customer satisfaction and increasing both conversion rates and customer lifetime value. A seamless RUX ensures that returning users, whether identified or anonymous, encounter minimal friction in processes like logins and checkouts, and experience personalization based on their previous interactions with the brand. This approach not only fosters loyalty by making customers feel valued and respected but also has the potential to significantly boost revenue, as personalized experiences can lead to a 40% increase in earnings. Device intelligence plays a crucial role in accurately identifying returning visitors, surpassing the reliability of cookies or IP addresses, and thus supports a robust RUX strategy by ensuring security and reducing the risk of fraud. Companies like Fingerprint leverage device intelligence to improve user identification, reduce multi-factor authentication, and enhance customer satisfaction, ultimately leading to better brand perception and reduced operational costs.
