What is Buffer?
Buffer enables your cardholders to make payments from their main account, even when it is empty, if they have funds available in a second account.
For instance, a customer with separate current and savings accounts can complete purchases on their usual card at times when their current account is empty.
Buffer assesses both accounts, runs an almost instant approval process and completes the transaction with funds from the second account. The customer will barely notice a difference at point of sale – fully frictionless payments.
