Demystifying QR Codes, RFID, and NFC

How to Use QR, RFID, and NFC to Capture Data and Improve Your Events
Today’s event tech enables you to capture data and use it a number of awesome new ways. You can make networking easier, provide useful event info for attendees, create more value for your sponsors and gain more insight into what’s working at your event.
Useful attendee data can take a few different shapes: first party data (obtained through event registration) is one example, as well as traffic or event location patterns. When it comes to collecting and utilizing this information to your advantage, there are a few options, each with their own benefits.
Here, we’ll break down the options – and show you how to make the most of each one.
Quick Response or QR codes can be used for networking, gamification and tracking. To create one, a barcode is printed on an attendees badge or used at a sponsor booth. This is the tech replacement of a business card exchange – you simply use your event app to scan the code and you’re connected to that person. From there, you can see their profile, make notes on that contact, set up a meeting and communicate through messaging. Once scanned, a connection is filed into a “my connections” list for future access. QR codes are a simple, cost effective entry into networking.
This option makes it easy to establish attendee-to-attendee as well as attendee-to-sponsor connections. Connecting to a sponsor is especially helpful when it comes to gathering or sharing a company’s info, profile, assets, quizzes and polls. Furthermore, making connections and participating in quizzes can be included in gamification: points can be awarded for each connection or response made through the code.
Because QR codes can be scanned anywhere, they can also be used for registration and tracking. For example: when someone checks into a session, they can be sent a quick welcome push notification. You can also request that attendees scan out when exiting a session to track time spent. Capturing this data and then generating an exit survey can be useful in measuring the success of your sessions.
RFID (Radio Frequency Identification) technology is used for tracking, information gathering, accessing sessions at large events and cashless payments.
RFID technology uses small computer chips and antennas to store data, creating a unique identifier. The technology is contained in “tags” which are small enough to fit on event badges and bracelets, creating an RFID badge system. Tags are assigned to each attendee prior to the meeting, and then fixed to attendee badges. During the event, RFID scanners (which are about the size of a thumb drive) pair with a tablet or phone to collect data.
RFID is most commonly used to check attendees into sessions. It’s especially beneficial when it comes to groups – to control access to events, log continuing education or mandatory training credits and speed up merchandise exchanges.
For large scale events and festivals, RFID technology can be useful in making security lines run more smoothly. At a scanning station, attendees can simply swipe their bracelet or badge for admission. Or, for example, beverage tickets can be provided to guests and stored in their tags. Attendees can also link their credit cards with their RFID tag to allow for cashless payments.
Similar to QR Codes, an RFID app makes registration and welcome messages (via push notifications) easy, and can also track an attendee’s time spent at any particular session. After a guest has registered and/or scanned out of a session, you can generate surveys and analyze traffic patterns. This level of detail can help you gather valuable insight on popular features, bottlenecks, security issues and venue layouts. Learn more about RFID technology and its benefits here.
NFC (Near Field Communication) allows peer-to-peer communication between devices. When two devices are close to one another (or when touched together), data can be exchanged – no internet connection needed.
NFC is derived from RFID technology; it’s essentially two chips that talk to one another. Have you ever used Apple Pay where you hold your phone up to a card reader to make a purchase? That’s it in a nutshell.
Apple Pay had once been the only application granted access to the iPhone NFC chips. While this access has always been available in Android phones, it is not utilized as it would not include those attendees with alternative devices.
The use of NFC could change the networking process. Using NFC vs. QR codes, RFID technology and beacons, simply tapping or bumping a phone can exchange information, with no internet, badges or bands required.
