Data pad
From Tardis Wiki, the free Doctor Who reference
Dorium Maldovar carried a data pad from which he could access records of unpaid bar bills at the Maldovarium. When the Eleventh Doctor crashed into the Maldovarium, Dorium used it to identify his bill, which amounted to 12 credits.
Dorium took his data pad with him in his hovercar when he and the Doctor travelled towards the Beacon. It was cracked when the hovercar overturned. (AUDIO: The Light Keepers)
