A Temporary Debit Authorization Hold. For debit card purchases, some merchants request a temporary hold on your account for a specific sum of money when the merchant may not know the actual dollar amount of the transaction at the time of authorization (i.e., gas stations, restaurants). The amount of the temporary hold may be more than the actual dollar amount of the settled transaction (purchase). When this does take place, our systems cannot determine that the amount of the hold exceeds the transaction if that takes place. This temporary hold and the actual amount charged will be adjusted to the actual amount at settlement but could take up to three calendar days or longer in some cases before that final adjustment is final and settled. Until that final adjustment happens, the amount of funds in your account available for other transactions to clear will be reduced by the amount of the hold. If another transaction is presented to us for payment in an amount greater than the funds left after the temporary hold, you will be charged an insufficient funds fee according to our Occasional Overdraft Privilege Service Policy. You will be charged the fee even if you would have had sufficient funds in the account if the amount of the hold equaled the purchase amount.
