4. Your card was not charged twice, we promise!! We've had a frequent request to review transactions lately. This occurs when your card is "pre-authorized" with items on your tab and the point-of-sales system checks the bank account for adequate funds. Later when the tab is closed, the card is re-authorized for the full amount. Only the final amount is deducted from your account once the transaction clears and goes from "pending" to "final."
