A credit card or similar identification card is constructed in the form now commonly accepted with the added step of making one segment easily separable from the card to be carried separately usually in the pocket or on a key chain and reinserted upon presentation. The segment carries a portion of the owner's name and a portion of the serial number of the card, and the segment is not completely separated from the card as originally submitted to the owner. This feature facilitates production and handling of the card and the owner can use the card without detaching the segment if he is not concerned with achieving the extra protection resulting from carrying the parts separately.
