Basically I sold my debit card to a stranger being paid $300 for it, they told me that they can't open a bank account so they are going to use it just a regular debit card. I assumed that they can't do any harm to me as it is a debit card and it has only what they deposit in it. I have the online banking details and can check on the statement everyday, so far they used it at supermarkets. So, what else can they do beside depositing/withdrawing money from the card? Can they sign a contract of some sort or lend money on the card? They also have the online banking details. I was being told at the bank that they can't go overdraft on it. I really didn't wanted to do it, but I am in a really tight situation right now, so the money went only for food actually...
