These holders are commonly used for ID badges, access cards, student IDs, conference passes, and employee badges. Here are some popular types: 1. Standard Plastic Badge Holders Material: Clear, rigid PVC or polypropylene. Features: Single or double-sided (allowing cards to be visible from both sides). Slot for inserting a card (top-loading or side-loading). Hole punch or slot for attaching to a lanyard. Sizes: Common sizes include: Credit card size (3.375" x 2.125") Vertical badge size (3.5" x 2.25" or 4" x 3") Horizontal badge holders (for landscape orientation). 2.
