Everyone has at least one photo ID card. In an age when identity theft is increasingly common, it's important to have a secure method of manufacturing photo IDs-- whether they be drivers licenses, student IDs or passports. And while government ID cards are the most common type of ID, photo IDs emerge in other arenas as well. Employers often issue ID cards to staff to distinguish between those with different levels of security clearance for access purposes. It's also possible to use employee ID badges as time cards.
