Vertical Slot Punched Cards are blank so you can print them however you wish to. The slot allows the card to be attached to a lanyard, ID clip or badge reel. For added protection the cards can be placed in a plastic badge holder that is made for slot punched cards. Having a slot punch on the card itself actually means that when the card is placed in a badge holder, it is secured at an extra point for added security. These cards are made of the highest quality plastic and are a standard card size so they can be used for many different purposes.
