Why is CR80 the standard ID card size?
CR80 matches the footprint of a credit card, so the cards fit standard wallets, badge holders, slot punches, lanyard clips, and card readers without modification. That universal compatibility is why almost all printed ID cards, access badges, and gift cards use it.
