Hi @Petrus,
OJS currently only includes the manual and PayPal payment methods, but these are written as plugins, so adding more would not represent a lot of work for a developer. The PayPal plugin in particular uses the Omnipay library, which provides support for a lot of different payment tools. If one there is a good option for operations in Iran, then copying and adapting the Paypal plugin would not take much effort.
