Why choose QR codes for event check-in? 

In 2019, the worldwide market for the events industry held an impressive valuation of USD 1.1 trillion. According to industry forecasts, this figure will surge, reaching an estimated USD 2.1 trillion by 2032. This surge represents opportunities for event organizers and underpins the growing importance of efficient methods like QR code check-ins in managing events. 

QR codes, or Quick Response codes, serve as a tech-savvy alternative to support and streamline an effective event check-in process, paving the way for seamless registration and elevated attendee experience.  

Almost any event can benefit from QR code check-ins due to their inherent convenience and efficiency, but they are especially advantageous for large-scale gatherings such as conferences, music festivals, trade shows, and sporting events where handling huge crowds can be a logistical challenge. 

Smaller-scale events like workshops, seminars, and networking meetups can also leverage QR code check-ins for a smoother, more professional registration process. Here are some example situations that make QR code check-ins a game-changer: 

  • Large conferences: With potentially thousands of attendees, manual registration can cause long lines and delays. 
  • Music festivals: Attendees often misplace or lose their paper tickets amidst the excitement and crowds. 
  • Trade shows: These events often involve multiple entries and exits. 
  • Workshops and seminars: These events usually involve a smaller audience, but the need for professionalism is high. 
  • Networking meetups: Attendees at these events are often busy networking and connecting with peers. 


Expo Logic, an industry leader in the top technologies for event registration, provides an efficient and user-friendly platform for implementing QR code check-ins. Our solutions are not just a logistical tool but a strategic asset for event success. 


The role of QR codes in event check-in 

Before we dive into the benefits of using QR codes for event check-in, let’s first understand how QR codes work. QR codes are two-dimensional barcodes you scan using a smartphone or an event ticket scanner that represent information, such as URLs or ticket numbers, in a visual, machine-readable format. When QR codes are scanned, the scanner decodes this information and takes the corresponding action. 

When a participant scans a QR code during event check-in, the code can trigger a few different actions, including the following: 

  • Ticket verification: The most common action is verifying the user’s ticket. The QR code contains the ticket number or unique identifier, which, once scanned, verifies the attendee’s registration and grants them access to the event. 
  • Contact details collection: QR codes can also quickly collect or confirm attendees’ contact details, which can be particularly useful for networking events where exchanging contact information is often a primary goal. 
  • Session registration: For events with multiple sessions, QR codes can register attendees for specific workshops or talks. After scanning the QR code, attendees are registered for their chosen session and receive immediate confirmation. 
  • Lead capture: QR codes can capture leads for trade shows or business events. Attendees scan the QR code to download exhibitor information or sign up for newsletters, automatically providing their contact details. 
  • Content access: QR codes can lead to event material or exclusive content, such as anything from the event schedule, presentation slides, or a special host video message. 

Implementing QR codes in event check-in processes eliminates the need for manual check-in, reducing long lines and wait times. Additionally, QR codes can provide organizers with real-time information about attendees’ arrivals, which can be useful for tracking attendance and managing crowd flow. 


Benefits of using QR codes for event check-in 

The advantages of employing QR codes for event check-ins are manifold, which evidence why they are an increasingly popular tool in event coordination. 

Streamlined and contactless check-in process 

With QR codes, the check-in process becomes a swift, self-directed activity. Attendees simply present their personal QR code — typically available on their mobile device — for scanning, removing the need for handling physical tickets or interacting with staff for manual check-ins and promoting a contactless experience. QR codes expedite entry and significantly reduce potential transmission risks associated with physical contact — an essential consideration in today’s health-conscious society. 

Enhanced data accuracy and attendee tracking 

With a QR check-in, data collection accuracy drastically improves. Since you automate the scanning process, you eliminate common event registration mistakes, like human errors often associated with manual registration, such as misspellings or incorrect data entry. You can accurately and instantly capture each attendee’s information the moment you scan their QR code ticket.  

Moreover, QR codes not only record the exact time of an attendee’s arrival, but they can also track the attendee’s movement within the event. Organizers can know in real-time which sessions are popular or which booths have the most traffic and can adjust the event’s logistics accordingly. 

Improved attendee experience and reduced wait times 

When an attendee only needs to scan to register, they avoid long queues or delays at the entry point, greatly enhancing their experience. This self-service check-in process is not only convenient but also adds an element of control and autonomy to the attendee’s experience.  

As mentioned above, the real-time data QR codes provide allows event organizers to manage crowd flow more effectively. If certain event areas become overcrowded, organizers can redirect attendees to less congested areas, enhancing the overall comfort and experience of the attendees. 


QR codes vs. traditional check-in methods 

Before QR codes, traditional event check-in methods involved printed tickets or physical registration lists — and while these methods were effective, they had their limitations. Let’s compare the use of QR codes for event check-in to traditional methods. 

The advantages and disadvantages of traditional check-in methods 

Traditional check-in methods have proven their worth over time. Physical tickets or onsite registration are straightforward and require no additional technical know-how from attendees, also providing a tangible token of event attendance, which attendees can keep as a memento or use for record-keeping purposes. 

However, traditional methods also come with a fair share of drawbacks — the process can be slow and labor-intensive, leading to long queues and wait times, impacting the overall attendee experience.  

There are also logistical challenges in the event of lost or misplaced tickets. Moreover, traditional methods cannot provide real-time data or insights about attendees, rendering crowd management and event optimization difficult. 

Finally, using physical tickets or lists contributes to higher printing costs and poses environmental concerns. With the growing emphasis on sustainability, event organizers must look for more eco-friendly alternatives. 

The advantages and disadvantages of QR codes for events 

A QR code check-in system introduces a whole new level of efficiency and convenience to the event check-in process. The two-dimensional barcodes are quickly scanned using a smartphone or a specialized device, facilitating an almost instantaneous check-in process. This speed dramatically reduces queues and wait times, improving the attendee experience significantly. 

Moreover, QR codes can provide real-time data about arrivals, departures, and overall attendance, which is invaluable for crowd management and event optimization. Being digital, they also reduce printing costs and are a more environmentally friendly approach. 

However, QR codes are not without their disadvantages, requiring attendees to have a smartphone or a device capable of reading the code, which may be a barrier for some. Additionally, there’s a reliance on technology and internet connectivity with QR codes — a technical glitch or network outage could disrupt the check-in process. 

Lastly, while QR codes may offer convenience and efficiency, they lack the tangibility of a physical ticket, which can sometimes detract from the overall event experience for some attendees. 

QR codes are generally secure for event entry, however. Event organizers can encrypt the information encoded within a QR code, making it difficult for unauthorized individuals to decipher. Furthermore, each code can expire after a certain period or after being scanned once, reducing the risk of duplicates or fraudulent entries. 

As with any technology, working with a reputable provider and implementing appropriate safeguards to protect against potential threats is crucial. Organizers and attendees should only scan codes from trusted sources to prevent potential issues.
