Your credit card number, or in industry parlance, Primary Account Number (PAN) is embedded in a primitive magnetic stripe on the back and, just for good measure, typically embossed on the front. There is no meaningful security on the card itself. For use in phone/internet transactions, the card also has a three- or four-digit security code printed on it as well, though this number is not absolutely required for transactions, and seems to be requested only at random. When you go to a store, you swipe your card and your plain-text PAN is seen by the merchant, then sent for verification through what you hope is a securely-encrypted connection to the credit card processor.

Apple Pay generates 16 digits numbers that look like CC numbers to the merchant but are one-time use only.
