What are you talking about?
The scam going around is that a cheque is sent and the shopper is told to deposit the cheque, keep a certain amount for the fee and return the rest. The scam is that the cheque is a fake and the shopper winds up on the hook for the entire amount of the deposited cheque.
I don't see how depositing a cheque would give anybody access to your account. Could you please clarify?
