Dual display guidelines

The following points summarize the standards of good practice for dual display advocated by the European Monetary Union.

  • The fixed conversion rates must be used when calculating the counter values in dual display.
  • Rounding to the nearest euro cent must be adhered to as a minimum standard of accuracy for monetary amounts that have been converted from a national currency into the euro.
  • It should be possible to distinguish between the primary currency and the counter value, which is displayed for information purposes only.
  • Prices should not have an excessive number of digits. Dual display of prices on individual products can be limited to the final price that consumers have to pay. Dual display on receipts from retail outlets and on other financial statements can be limited to the total amount.
  • Merchants should indicate clearly whether they are prepared to accept payment in the euro during the transitional period.
