Paper based invoices are still commonly used in Norway where users manually copy large amounts of digits in order to set up transactions. Such digit copying tasks are cognitively and visually demanding, errors are easily introduced and the process is often perceived as laborious. This study proposes an alternative scheme based on dictionary coding that reduces the cognitive load on the user by a factor of five. The strategy has improved error detection characteristics and the scheme is easy to implement.
