French to English Other Finance (general)

This is found in a text about a savings account (compte sur livret) and refers to the "compte support" to which the client makes the initial payment that is then transferred to the savings account and which receives the interest paid on the savings account. I have found this information: Le compte support « compte de prélèvement » est le compte sur lequel est prélevée la somme à bloquer. Il recoit aussi le remboursement du capital et les paiement d'intérêts."

Thanks!
