Notify your bank as soon as possible to limit your losses. If your debit card was stolen and used fraudulently, you can usually get reimbursement for those transactions.
Your loss will be limited to $50 for an ATM card if you notify your bank within 2 business days after the card is lost or stolen. Your loss could be up to $500 if you fail to notify your bank within 2 business days. If you don’t notify your bank within 60 days of receiving your statement, you could also face unlimited losses on transfers after the 60 day period.
