is she foreign? Some EE girls use paysafe and similar to repatriate cash to their homes. Could be its easier for her to receive vouchers rather than have to go to the shop herself - especially as you'll pay the fee, not her.
Also if she's seeing punters without her pimps knowledge, vouchers are easier to hide
Interesting thought Scutty.
Set up a small business somewhere abroad and accept PaySafe.
Pay your own business with vouchers accepted from a UK customer.
Not much of an audit trail for the Police or Revenue to follow and no large sums of cash to hide or explain.
Is there anything on the Paysafe site about using vouchers internationally?
