Payoneer is an online payment system and peer-to-peer payment system that allows you to transfer money to anyone anywhere in the world, in addition to making purchases. It provides you with a pre-paid Mastercard that you can use anywhere Mastercard is accepted.
Payoneer is really popular for freelancers because Payoneer has a relationship with many freelancing sites. The downside of Payoneer is that it has a variety of different fee levels ($0, $2, or more), depending how you use the service.
