Your Scotiabank credit card has many layers of security, starting with your signature.
Your card also features a personal identification number (PIN), which is a private code that you select. Your PIN is required for all ATM transactions, with some cards requiring a PIN for all transactions. Do not share your PIN with anyone. Depending on the type of credit card you apply for it may feature an extra code on the back of the card, which allows certain transactions to be performed only with the actual card in hand.
