There are many questions that can be raised pertaining to the practicality of RFID-enabled giveaways, but some events are already using them. For example, has a “Lolls Cashless” scheme which allows festival-goers to pay for food and drink without having to carry around money. Event rite champions a similar RFID system, focusing on the way the tags could be used to manage entry flow.
Other events and conferences could implement the technology in a similar way, but with more emphasis on the data accumulation side of things than the entry and exit tracking. Guests could add their details and preferences to an online database when they buy tickets. When they get to the door, they could pick up a tagged t-shirt, a wristband or a lanyard linked to their account, and filled with their personal details.
Exhibition stands could eventually have RFID readers on them, allowing hosts to tailor their spiel precisely to the interests of their potential attendees.
