## The use case: how Chipper Cash deploys Pinecone

Chipper Cash uses Pinecone as the vector database in a facial verification system that compares each new user's selfie embedding against existing users' selfies to detect duplicate sign-ups in real time. This helps block fraudulent accounts that abuse new-user promotions.

Summary written by usedby from the source page, in English. The figures are those of Pinecone and Chipper Cash, not ours.

> Since launching the facial verification system with Pinecone, Chipper Cash has seen the number of fraudulent sign-ups decrease by 10x.

- **95%**: “New users’ selfies are verified with over 95% accuracy in less than 2 seconds.”
- **200 milliseconds**: “This allows them to retrieve similar selfies of a user in under 200 milliseconds so they can catch and prevent fraudsters without slowing down legitimate new users.”
- **16%**: “During a six month period, Chipper Cash lost 16% of their promo budget to fraudulent sign-ups — whether duplicates or users with fake or stolen government IDs.”

> It took us less than a month to build our new in-house facial verification system. We have a real-time, scalable, and secure system thanks to Pinecone. End-to-end latencies for the entire system dropped from up to 20 minutes previously to less than 2 seconds now, with Pinecone doing the search in under 200ms.
