Device Fingerprinting

What is Device Fingerprinting?

Device fingerprinting is a technique used to identify a specific computer or mobile device based on its unique configuration and software settings. It collects data points such as browser type, operating system, screen resolution, and installed fonts to create a distinct identifier.

Why It Matters

• It helps detect fraudulent activity by identifying when multiple accounts are being accessed from the same suspicious device.

• Unlike cookies, device fingerprints are difficult for users to delete or bypass, providing a more persistent tracking method for security.

• It allows merchants to recognize returning customers and apply less friction to their checkout process.
