Remember to be vigilant this holiday shopping season. Check your statements and transaction history often to ensure all the purchases are valid. Shopping from the comfort of home on Cyber Monday? Make sure you’re on a secure site. The url should start with “https”. The “s” is for “secure”. When it’s time to process the online payment, make sure there’s a security icon on the page; most often it appears as an image of a lock. But rest assured, as a First Source card holder, you are not liable for fraudulent purchases on your First Source credit or debit cards.
