Evidence Vault

Evidence Captured
Before the Dispute

3D Secure, AVS, CVC, device fingerprint, and IP address — captured on every payment, timestamped with RFC 3161, ready when you need it.

The Problem with Chargebacks

Without Evidence Vault

  • Dispute filed → scramble to find evidence
  • 3DS/AVS/CVC data not stored or already expired
  • No device fingerprint or IP — weak fraud defense
  • No proof of when evidence was collected
  • Bank sides with cardholder by default

With Evidence Vault

  • Evidence captured automatically at payment time
  • 6 data points on every transaction
  • Device fingerprint ties purchase to customer
  • RFC 3161 timestamp proves collection time
  • Evidence auto-attached to dispute responses

6 Evidence Points on Every Payment

🔐

3D Secure

Authentication result and version. Proves cardholder verified the purchase.

📍

AVS

Address verification status. Confirms billing address matches card.

CVC

Card verification code check. Proves card was physically present.

🖥

Device Fingerprint

Browser, OS, screen resolution, timezone. Ties purchase to specific device.

🌐

IP Address

Customer's IP at time of payment. Shows geographic consistency.

RFC 3161 Timestamp

Legally admissible proof of when evidence was collected. Certified by independent TSA.

How It Works

1

Install

Install Evidence Vault from the Stripe App Marketplace. Enable in Settings. Add collect.js to your checkout for device + IP capture.

2

Capture

On every successful payment, 6 evidence points are captured and timestamped with RFC 3161 — automatically, in under a second.

3

Defend

When a dispute hits, vault evidence is auto-attached to your response. Pre-timestamped evidence that existed before the dispute — hard for banks to ignore.

Better Together: Vault + Reflex

Evidence Vault captures proof before the dispute. Reflex defends it after. Together, they give you the strongest chargeback defense available — and Reflex users get a 33% discount on Vault.
