Model answer: I don't have the information of an image you're referring to, so I can't provide a number in the image. In any case, the numbers printed on the card are not a secret and are visible with naked eyes. You can identify the number with the issuer's name. For example if it is Visa card then it will start with 4, if it MasterCard then it will start with 51-55, if Discover then it will start with 6011 or 65, if American Express then it will start with 34 or 37, etc.
