Booking.com processes payments across more than 220 countries. Andreas Zodhiates, their Head of Payment Fraud, described a challenge that maps directly to Shopify's merchant protection problem: cookie-based identity is the signal every fraud ring already knows how to defeat. The detection layer has to move down to the device.

After integrating Fingerprint, Booking.com could trace a fraud ring that had created 40 accounts over six months back to a single cluster of hardware. Each account looked distinct in the transaction layer. The device signal made them identical.

The second half of that description matters as much as the first. When the device is known and trusted, checkout friction is unnecessary for that visitor. Fingerprint's 99.5% accuracy means the platform finally has a durable signal to distinguish real customers from bad actors, and can concentrate friction only where the risk is real.

For Shopify merchants, cart stuffing is the clearest version of this problem. A bot that stuffs a cart under 50 different sessions is invisible to any system reading session IDs or IP addresses. The device signal sees one actor. That single signal is what unlocks cart release policies that don't also punish your real customers.

If you want to see what this looks like against a real traffic sample, we can walk through the integration and the signal in a 30-minute session.
