Shopify's own way: Fraud Control
- In your Shopify admin, open Apps, Fraud Control, then Rules, Create rule.
- Add the customer's email, an address detail such as the ZIP code, or the IP address. Save.
- A matching checkout fails with an error. Checkout rules need Shopify Payments.
It stops the exact value you typed. Keep it for the email you know, and RefundSentry for a new account on the same card.
