About Blockio Card Testing Blocker

Card testing is when bots run stolen card numbers through your checkout, leaving a burst of small declined payments and gateway fees for orders you never received. Blockio scores each checkout attempt on device, bot, velocity and direct-checkout signals, then applies it inside Shopify's checkout — so express checkouts like Shop Pay are covered. Choose Monitor, Balanced or Aggressive. Country, IP, VPN and proxy blocking are included. If Blockio is unreachable, checkout carries on.
