A new ways for tourists to make payments in Iran

As I have mentioned before one of the most important problems that tourists have in Iran is carrying cach, Credit cards are useless here, Due to sanctions you can't pay by credit card, in my previous post I told you about gift cards. That's a good way to have your money in the gift card and you can pay with that.
Today Iran tourism organization announced that they are issuing a kind of gift cards at the airprts, So when a tourist comes to Iran, He can pay cash in Iran Rial, Dollar or any other currencies and get one of those cards for the amount they are worth, and makes payments during the time he stays in Iran, And when he leaves the country he can return the card and get the remained balance in cash.
