Asking for a friend: Decoding card security

With TD Fraud Alerts, if we detect a possible suspicious transaction on your or your Additional Cardholder's credit card, and we have your current mobile phone number on file, we'll send you a text message. If you recognize the transaction then all you need to do is reply Y to the text. But if you don't recognize the transaction, then reply N and we'll respond with instructions to call us and we'll investigate that transaction.

Feel more confident if you temporarily misplace your credit card by locking your card using the TD app. Locking your card means you can't use it to make any new purchases or pay using your digital wallet. When locked, pre-authorized payments will still go through, credit card payments will still be accepted, and you can make transfers.
