About the Halt: Card Testing Blocker
Halt protects your Shopify checkout from card-testing bots that use stolen credit cards to make repeated payment attempts. This fraud prevention app detects suspicious checkout activity by identifying repeat attempts using the same email address, phone number, or shipping address, then blocks them before any card is charged.
Stop automated bot attacks with a bait product trap that catches card testers in action. Block throwaway email addresses commonly used in fraudulent transactions. Every blocked checkout is logged with a clear explanation of why it was stopped, giving you full visibility into threats targeting your store.
Start with watch mode to see exactly what Halt would block before activating full protection. Get instant email alerts when card-testing attacks are detected so you can monitor fraud attempts in real time while legitimate customers complete their purchases without interruption.
