Online gambling companies face the challenge of balancing security with user experience while complying with strict Know Your Customer (KYC) regulations, which can create friction if not managed smoothly. Device intelligence offers a solution by enabling sites to recognize returning users through unique visitor IDs, enhancing the return user experience (RUX) with seamless logins, personalized content, and reduced security hurdles for trusted devices. This technology helps online casinos and sportsbooks differentiate themselves in a rapidly growing market, projected to expand significantly in the coming years, by retaining players through a more engaging and hassle-free experience. Companies like Fingerprint utilize device intelligence to improve user retention while maintaining high security standards, identifying over 4 billion unique devices annually, and ensuring compliance with global data protection regulations.
