Businesses in the ID cards category produce and supply identification cards for organisations, venues and events. Typical products include photo ID cards for employees, students, contractors, visitors and members, as well as event passes and temporary badges. Cards may be printed on plastic or other suitable materials and supplied with lanyards, badge holders, clips or protective sleeves. Services can include preparing card artwork from customer-provided details, printing names, photographs, job roles, membership numbers, barcodes or QR codes, and producing replacement cards. Some suppliers also provide card printers, consumables and systems for making cards in-house. Where required, cards may be encoded for use with compatible access control, time and attendance or membership systems. These are generally organisational credentials rather than official identity documents issued by government authorities.
