They are used for everything from access to facilities to brand promotion. Whatever roll they take for you the point is they are important. Badge holders are here to protect these cards. Instead of messing around with a slot on your card you just slide the ID in and you are good to go.
These holders are a thin clear vinyl that will proudly display your ID on a lanyard, badge reel while protecting it from those inevitable coffee spills. They are designed to hold and ID card that is similar in size to credit/debit cards. The edges are reinforced for extra strength. This means the holder won’t rip when you accidentally close it in a drawer at your desk. And if it does rip, the badge holders are sold in packs of 100 so maybe there is an extra for you.
