Unknown Shopper: Understand the Person Behind Every Transaction

Most retailers don’t truly know their customers. Unknown Shopper from Fiserv links transactions across channels, cards and wallets to resolve identities – securely and at scale. The potential results can be significant:

• Achieve up to 65% match rates by securely linking real consumer identities to transactions
• Attain 2x to 3× greater reach and 3x to 4× better accuracy than traditional look‑alikes, validated through backtesting of deterministic and probabilistic methods versus a transaction‑based model 
• Activate smarter media with verified, purchase‑based targeting, and close the loop with real‑time, sales‑tied attribution
