I don't know alot but I do know that you have to pay a fee for every transaction, that is why when you are shopping, you will sometines get a better deal if you are paying by cash. The fee may be different for different banks, I would phone and ask. I was told it wasn't worth it for me, I organize a major craft sale and have only been asked a few times if I take Visa or Mastercard, when I say no they pay by cheque anyway.
