a discount code is not found on a credit card... i am guessing you saw this 'discount code' from a website that you were trying to buy something from... the discount code would be found on a coupon from this store. ex. if you received a coupon from walmart... you could go onto walmart.com, put in your credit card information, and enter the zode from the coupon to receive a discount.
The security code is not only on the back of the card. Example: American Express puts it on the front. The basic concept is simple. This number is only phisical.... meaning that it is not also encoded on the credit card magnetic stripe. The result is, that if you know and can provide this code, you have the physical card in your possesion.

The CVV (Card Verification Value) is a three digit code on the back of the credit card, which is calculated using a certain formula, using the credit card number. It is an added security measure in case an unauthorised person is able to copy down your credit card number, and is also an easy way to determine most 'fake' numbers.
