      • Why can't my buyer try paying by card again at checkout?

      When the same buyer has their card refused several times in a short period, the checkout blocks new card payment attempts for up to 30 minutes and shows a too-many-attempts message. The block is temporary and ends on its own.

      This protects your product against card testing: fraudsters use checkouts to find out which stolen cards still work, and every attempt creates refusals, chargebacks and risk for your account.

      What counts as a refused attempt

      • Only card refusals from the payment provider count, such as insufficient funds or an unauthorised transaction.
      • Form errors, such as a missing address or invalid instalments, do not count.
      • Attempts are counted by the buyer's connection, browser and email. Changing only one of them does not lift the block.

      What the buyer can do

      1. Pay with Pix or boleto, which stay available during the block, if your offer accepts these methods.
      2. Or wait up to 30 minutes and try again with a card the bank approves.
      3. If the card keeps being refused, contact the issuing bank. The refusal comes from the bank, not from the checkout.
