The Russian payment system Mir is to be introduced in Iran.
This was announced by Iran's Deputy Foreign Minister Mehdi Safari, the Russian state news agency Ria Novosti reported on Wednesday.
Due to international sanctions, Iran and Russia are largely excluded from international payment transactions.
Business people often have to bring large sums of cash with them to invest in Iran.
After the attack on Ukraine, the West imposed sanctions on Russia in the financial sector, among other things.
Many financial institutions have been excluded from the banking communications network Swift.
The world's largest credit card operators Visa and Mastercard suspended their business in Russia.
Iran is also affected after the country was hit by sanctions in the dispute over its nuclear program.
Just over a week ago, Iran's supreme leader Ayatollah Ali Khamenei stressed during a visit by Kremlin chief Vladimir Putin that Tehran and Moscow had to work together on Western sanctions.
Khamenei also called for the dollar to be weakened as an international currency.
