Events and exhibitions offer plenty to explore: seminars, networking and an array of companies whose salespeople want to meet you. With time short, anything that speeds up the door or the session scan gives you minutes back for what you came to do.
At a well-run show, you tap or scan as you enter a session, ask for information or take a survey. Your education credits add up accurately and your inquiry gets a real answer. When it does not work that way, it usually helps to know what is going on behind the badge, and who to ask.
Badges and passes are getting more flexible. A changed session schedule can often update your access right away, with no need to wait for a new badge. The articles below explain how your credential works, what it records about you and how to get more from it.
Name, company, an ID number and sometimes more. What a badge stores, who can read it and what you can ask for.
A code in your phone's wallet can replace the queue at the badge desk. What works today, what still goes wrong and what to carry.
