The Czechoslovak koruna (crown) was a soft currency, that is, not exchangeable for other currencies outside the country. In 1948 shops were established under the name Darex to sell goods to foreigners for foreign (hard) currency only (based on the earlier Torgsin shops in the Soviet Union). Later, these became open to ordinary citizens, but not for crowns. In 1950, to speed up transactions and limit fraud, foreign currency was first converted into Darex vouchers in values of crowns.
