Give this script to your alt, ensuring their balance is L$0 (or setting the balance in the variable below then allow debit permissions when the object requests them.

You can then manage your alt's balance using the object, without the alt having to be logged in. To deposit lindens, pay the object. To withdraw lindens, touch the object for a menu.
