Note: While this service minimizes carding attacks, please be aware that customers are responsible for any transactional fees imposed by PayPal, or their bank, that result from carding attacks. Note: Any accounts that opt out of the carding module and set their account to Whitelist are fully responsible for any fees associated with carding on their account. Batch processing transactions is an example of a business model that might generate high declines and invalid transactions. If your business model generates a high number of valid declines or invalid transactions within a brief period, you have the option to set your account to 'Whitelist'. If the number of declines or invalid transactions exceeds the threshold set by PayPal, the carding module will be triggered and the account is blocked from processing any additional transactions until the block has been lifted/removed. Once the carding prevention module has been released, Payflow will monitor accounts for a high level of declines and invalid information provided. Payflow has implemented a carding feature that is designed to help merchants minimize fraudulent carding attacks and the costs associated with them. The feature will be enabled by default.
