Retailers will also have to consider temporary storage space for cash-boxes and additional transport requirements. The Riksbank is likewise working to make the period with double currencies as short as possible. There are, however, other aspects to consider. Incorporating euro in the system will take time. Just the work of distributing the new banknotes will be time-consuming. We shall be looking into what is feasible in practice. Time will also be needed to adapt the automatic teller systems (Bankomat and Minuten) to the new currency. Another matter to be investigated is whether the distribution of euro to banks, post offices and possibly retailers can start before the date on which the new currency becomes legal tender. Moreover, some consumer interests, for instance, have said than many consumers would prefer a relatively long changeover period in which to get used to the new currency. The question of the period with double currencies therefore calls for further discussion in order to arrive at a solution that everyone can accept. Retailers have also put forward the view that it should be possible to provide change only in euro from day one. We believe this may be difficult both in practice and on the grounds of the accepted BIS Review 41/1997  -5-  changeover principle of "no compulsion - no prohibitions". It has been said that people in general are to be free to decide whether to use euro from the start on 1st January 1999 or to wait until the changeover is completed in 2002.
