The only logic for a prostitute not taking cards appears to be the non declare of the income, be this in relation to HMRC, Benefits, housing etc.
Utter drivel, The pitfalls of obtaining and maintaining a merchant account are plenty but perhaps the most prominent is the liability aspect
from the merchants (wg) bank who are totally responsible for ALL the transactions the merchant transacts so to speak, thus the liability
is on their shoulders, the likes of VISA & Mastercard have enough hoops to jump through for the issuing banks without the merchant
giving them even more of a minefield to trawl through.
Liability wise and as a working example, should a wg be paid by credit card and then the punter when home decides it wasn't what he
wanted or to issue a chargeback and proceeds to do so....this would in effect cancel the transaction but given the act took place it
may then be offered that the girl consented because she was being paid, but as no payment was made this 'could' give rise to her
claiming she was raped and so on. Of course it's hypothetical but there lies one of a multitude of reasons why a girl but primarily the
banks that won't allow credit cards into the transaction.
To say nothing of most punters wanting to retain their identity and so pay with cash, why would they want a credit card coming home
