Protection Feature If an invalid DICT Key is submitted, it will automatically be added to a blacklist for a duration of one hour.
Cache Mechanism To avoid potential blocks from the BACEN DICT Control, the system caches bank account data for 3 months after the initial lookup.
Penny Test A penny test (a 1 cent transaction) will always be performed when the bank information is captured directly from the DICT to verify that the account is valid and can receive payments. This verification is not needed when using cached bank information. Please note that the penny test will be charged as a regular transaction.
