Organizers of many kinds of events provide attendees with Event Badges that typically display the person’s name, and sometimes additional information on his or her rights or privileges.  The main objective of event badges is to facilitate inter-action between attendees that do not know each other.  By seeing their name, and sometimes the organization they are associated with, other attendees can more easily approach them and instigate a conversation.  That is why event badges tend to be large-format, which just means they are 3 or 4 times larger than the typical credit-card sized ID card.  By having a larger surface area, there is more room to print the name and other information so it is easily and quickly read from a distance.  There is also more area to print colorful graphics unique to the event or the venue. 

A very important objective of event badges is to identify attendees who are authorized to enter the event.  Especially for high-cost events, or events which are in high demand, it is necessary to prevent unauthorized people from entering.  The event badge is a low-cost, efficient method of quickly determining whether someone is permitted to enter.  Even more, badges can be coded, with different colors or other printed codes, to determine within a large event whether an attendee can enter an exclusive area.  For example, at a concert badges indicate who is allowed to go backstage, and at corporate events badges show who has been granted access to VIP areas.
