RFID in a Nutshell

RFID in a Nutshell

Many of you have probably heard of RFID and how it can revolutionise an event by enhancing attendees’ experiences whilst making the process more efficient for the organisers. But what is it? How does it work? And where can it add value? Here we answer these questions and more…


What is RFID and how does it work?

RFID stands for Radio Frequency Identification and has been around for many years. In fact, we have all come into contact with it in our daily lives, often without even realising it.

It comprises of a two part system that allows the wireless transfer of information using small micro-chips and an antenna. The micro-chip contains a unique identifier and space to store information. When it is scanned, the information can be accessed and the reader can react accordingly. This may be by recording that micro-chip as seen, storing information held on the micro-chip, displaying a personalised message, or updating the information stored on the micro-chip.

Where is RFID used?

RFID is used in a wide range of situations for a variety of purposes, including:


Entry systems

  • In workplaces where employees place their badge against a reader allowing them entry onto a particular floor or room in a building, or even into the building itself
  • At sporting venues, such as cricket grounds, club members use their membership card on entry allowing the turnstiles to rotate


Public transport systems as a means of paying for trips, for example:transport

  • TfL oyster card in London
  • Adelaide Metrocard in Australia
  • Washington DC SmarTrip Card in the USA


  • Security – ever wondered what makes the alarms go off in shops? That’s right, RFID.
  • Contactless bank cards enable us to make payments up to £30
  • At festivals, for example Download, which went completely cashless in 2015 with a dog tag sized card attached to their usual wristbands

Restaurants for ordering foodrestaurant

  • At Vapiano, customers are issued with a card on entry, they tap in transactions at each counter and hand the card in at the till to pay




  • e-Passports contain a chip storing personal information, including biometric data, which is read at border control




The versatility of the system means it is highly adaptable in an event environment where it can be used for a variety of functions, such as:

Attendance managementattendance

Attendees can sign in for the event, or individual sessions, with those trying to register for the wrong session refused entry



Seating plansseating

Attendees can find out where they are sat quickly



Lead retrievalleads

Exhibitors scan the visitor’s badge registering their visit and allowing the exhibitor to record information about the visit




Attendees can be logged into the tablet they are allocated allowing our paperless solution to be personalised for each attendee




These can be linked to an attendee and accessed on any device




Provides a live delegate list with only people in attendance displayed enabling private messaging between individuals in attendance or even group chats


Custom activitiesactivity

Specific features can appear on certain tablets for table leaders or event hosts



Custom notificationsnotification

Can inform attendees of updates and information personalised for their event experience




Allows different attendees to have different voting rights as well as some polls only allowing certain attendees to vote


This list is by no means exhaustive. Contact us if you would like to find out more about the exciting possibilities available by integrating RFID into your event!
