Tripwire

Blocks card-testing bots before any card is charged. No extra step for real shoppers.

Card testing bots run stolen card numbers through checkout to find ones that still work, costing you processor fees and fraud-score damage. Tripwire tells bots from shoppers before a card is charged: shoppers earn a signed token by browsing; bots that jump straight to checkout don't have one. Two Shopify Functions remove card payment or block the order for tokenless low-value checkouts, while wallets stay available. It fails open, so uncertain cases are never blocked.

• Invisible storefront challenge mints a signed token while real shoppers browse
• Two Shopify Functions block tokenless low-value checkouts; wallets stay open
• Fails open automatically if tokens stop, so real sales are never blocked
• Admin dashboard shows protection status and prevented attempts
• Usage billing charges only for attempts actually prevented, via App Events API
