FasaPay has become a commonly used online money transfer service in the Southeast Asian countries of Indonesia and Malaysia in particular. The company behind the service is headquartered in Labuan, Malaysia, and it is accepted by a fair number of forex brokers that are targeting customers in that part of the world.
FasaPay is definitely less used outside of Asia than services like Skrill and Neteller. However, it is still a fact that some of the forex brokers that accept FasaPay as a funding method also operate out of the UK under the oversight of the Financial Conduct Authority (FCA).
