An identity document is any document that may be used to prove a person’s identity. If issued in a small, standard credit card size form, it is usually called an identity card, or passport card. The most common use of an ID card is to verify that the person holding it is indeed who she claims to be. You can then use it to match any additional information she gives you such as the address on an application form. Shawn effect is always with you for custom ID Card design.
