Card protection refers to measures taken to safeguard credit and debit cards from unauthorized use and fraud. This can include features like chip technology, which makes it harder for criminals to clone cards, and contactless payment options that require minimal physical interaction. Many banks also offer alerts for transactions, allowing cardholders to monitor their accounts in real-time. Additionally, card protection services may provide insurance against fraudulent charges, ensuring that users are not held responsible for unauthorized transactions. Some financial institutions offer virtual cards for online shopping, which can further enhance security by masking the actual card number.
