I have heard about new technology in place whare there are Name Badges that interact and store data. These might be used at a trade show, seminar, conference, symposium, etc. where instead of regular paper name badges, attendees wear an electronic name badge that had their profile loaded on to it. As attendees come in contact with others, the other person's profile info is basically scanned and loaded automatically onto the other's name badge. Then a record of all whom that person met along with each person's profile can be accessed later to track who attended, what types of people were there, contact info, other profile data, etc. Although I have heard of this technology, and briefly may have even seen some ads, I need help identifying and contacting companies that have these technologically advanced name badges. Can anyone help me out? Thank you.
