Looks like you have to "perform over 3 transactions per month, which lowers the maintenance fee to just $1" otherwise maybe the fee is higher?
Hard to know for sure since aside from the fact that you can't open an account or sign up for a card directly from Payoneer, there's this nice twist on the FAQ page too:
"...you may be obligated to pay certain service, maintenance or transaction fees. ... Costs are listed and explained when you sign in..."
So just go sign up (someplace else) and then we'll tell you what it'll cost you to use the service afterwards.
