The Planner’s Guide to Preventing Bottlenecks at Event Check-In

You’ve locked in speakers, sponsors, agenda, catering, décor, and yet the first thing your attendees will judge is none of that. It’s the line at the door.

In your head, it sounds like:
“Do we have enough stations?”
“Will the scanners read every ticket type?”
“What if the Wi-Fi drops?”
“Why does everyone crowd one line and ignore the others?”

Meanwhile, your attendees are thinking:
“I hope this doesn’t take forever.”
“Which line am I supposed to be in?”
“Why is that line moving faster than mine?”

That tiny window between the entrance and the moment their badge is printed is where you either confirm, “This is going to be a great event,” or trigger frustration before they’ve even stepped into the main hall.

What measures can you take to make it as smooth as possible? This guide breaks it down. From pre-event to during it, and afterwards, we’ve broken everything down for you. Let’s dig in!

Key Takeaways

  • Plan your crowd flow in advance, forecast peak arrival times, and create clearly segmented lines based on ticket type and attendee readiness.
  • Choose tools that match your audience and volume, such as QR scanning, onsite badge printing, kiosks, or RFID, and always test the full setup before the event.
  • Use roaming staff to remind guests to open their tickets, keep scanners active at all times, and move unprepared attendees to a side area so the line does not stop.
  • Train your team on scanning, printing, troubleshooting, and line management, and assign clear roles like line manager, scanner operator, and help desk support.
  • Expect tech issues and prepare backups such as offline mode, hotspot connectivity, spare devices, and manual check-in sheets so the line never stops moving.

Check-In Preparation Before the Event

1. Plan Crowd Flow Layout

Why This Matters

Inefficient crowd flow leads to confusion, misdirected guests, and slowdowns at check-in. If your attendees are unsure where to go or if multiple lines converge in the same space, it creates bottlenecks that impact the entire event’s timing.

How to Approach It

  • Map the Journey: Start by sketching out a detailed layout of your entry area. Break it down into clear zones, like entrance, check-in stations, badge printing, and security screening.
  • Design with Flow in Mind: Position your check-in stations in a way that accommodates the volume of attendees.
    Use one-directional traffic paths to guide people forward, reducing the chance of congestion.
    Place staff or signage at decision points where people might hesitate (e.g., at the door or near check-in counters) to direct them smoothly.

Event floor maps

The Benefit

This clear, intuitive layout minimises confusion, reduces unnecessary crowding, and lets your team focus on efficiently checking in guests rather than managing chaos. Your attendees will feel more confident, and your staff will execute the process with ease, leading to a calmer, faster check-in experience.

2. Leverage Data to Predict and Manage Attendee Flow

Analyze the right data to understand the impact of your event

Why This Matters

Predicting when and how many attendees will arrive allows you to staff check-in stations properly, set up technology, and reduce wait times. Without this data, you’re left reacting to unexpected surges, leading to frustration and delays.

How to Approach It

Use data to predict when and how attendees will arrive. 

To understand how experienced planners approach this, we spoke with Andrew Roby, a well-known corporate event planner who has worked with hundreds of events. He walked us through the key data points that drive his check-in strategy.

  • Start With the Numbers You Already Have
    This comparison between your current registrations and the past event numbers gives you a baseline for how many stations and staff you’ll need.
  • Account for Day-of Registration: If you’re allowing walk-ins or same-day registration, plan for significantly more stations and staff. Day-of registrations add unpredictability to your flow and typically require more hands-on assistance than pre-registered attendees.
  • Consider Your Check-In Window and Event Timing: The less time you give attendees to check in, the more stations you’ll need.
    For example, a tight two-hour window puts more pressure on check-in than a three-to-six-hour window.
    It also matters whether check-in happens before or during your main sessions. If it overlaps with opening sessions or breakouts, everyone arrives at once, and lines build up. But if check-in is scheduled the day before, arrivals spread out and flows stay much smoother.
  • Break Down by Attendee Type: Andrew also mentioned that different attendee segments behave differently. Early birds, VIPs, and group check-ins each have unique arrival patterns and processing needs.
    Analyse how each segment registered and checked in at past events to predict their behaviour and allocate resources accordingly.

  • Ask Your Tech Provider: Event technology providers like vFairs offer valuable data on check-in speed based on your event size.
    Whether you’re using iPad scanning or self-check-in kiosks, your technology provider can help you determine exactly how many stations you need.
    Self-service options like kiosks typically process attendees faster than manual check-in, allowing you to serve more people with fewer stations.
  • Use AI to Predict Peak Arrival Times: Advanced planning goes beyond just counting registrations. Use AI tools to analyse when peak check-in times will occur by factoring in external variables like flight arrival patterns, hotel check-in times, and typical travel schedules for your attendee base.
    This level of detail helps you staff peak periods more accurately.
  • Monitor and Adjust in Real Time: If your check-in software offers real-time analytics, monitor attendee flow as they arrive. Dashboards can provide live updates on wait times and line lengths. Use this data to adjust staffing dynamically by adding more staff to a specific station or redirecting attendees to less crowded areas.

The Benefit

When you have all this data with you, you can accurately match staffing, technology, and entry pathways to real demand. This prevents overwhelming surges, reduces wait times, and ensures your check-in system always stays ahead of the crowd.

3. Implement the Right Check-In Software

Why This Matters

The wrong tech is worse than no tech. Slow apps, manual spreadsheets, or untested QR tools can freeze your staff and irritate attendees. Technology should accelerate the process, not add friction.

How to Approach It

First, understand the main types of check-in technology and what they solve.

  • QR code scanning systems: These verify tickets quickly and work with phones and printed copies. Look for fast scanning speed, broad device compatibility, and reliable offline mode.
  • On-site badge printing: Use a badge printing software to print badges instantly at check-in. This avoids pre-printed badge sorting and supports last-minute changes. Thermal printers work best for speed and reliability.
  • Self-serve kiosks: These are perfect for tech-comfortable attendees. They reduce pressure on staff and help distribute the crowd across multiple entry points.
  • Facial recognition check-in: Provides touch-free, high-speed entry. Works best with consent-based audiences and in regions with supportive regulations.
  • Offline and backup syncing: Critical for events where Wi Fi may be unstable. Ensure the system continues scanning even without the internet.

The right check-in tech depends on your audience. Tech-hesitant crowds work best with staff-assisted QR scanning. Tech-savvy attendees prefer self-serve kiosks. For premium experiences, facial recognition delivers a wow factor (just ensure your audience is comfortable with it and local regulations allow it).

We asked Phoebe Cherry, Director of Strive, about the right way to go about check-in tech. Her take is pretty apt:

The Benefit

When you choose the right tech, you get faster lines, instant verification, fewer errors, and the ability to handle peak volumes without breaking down.

4. Use a Data-Driven Method to Estimate Check-In Stations

Why This Matters

The number of check-in stations you need depends on the number of people arriving at once and the time each check-in takes. Guessing often leads to understaffing during peak times.

How to Approach It

Is there a quick formula to know how many check-in stations you should have? Well, to make it easier for you, we asked Salman, director of Product at vFairs. He has been helping planners identify this for years. Here’s his take: 

A simple way to think about it is: stations ≈ (attendees arriving in 30 minutes × average check-in time in seconds) ÷ 1800.

Use this as a starting point, then adjust for your audience’s tech comfort, ticket types, and venue constraints.

You can also use this table to estimate the number of stations you’ll need:

  • Attendees in Peak 30 Minutes
  • 0 to 150
  • 150 to 300
  • 300 to 500
  • 500 to 1,000
  • 1,000 to 3,000
  • 3,000+
  • Suggested Stations
  • 1 to 2
  • 2 to 3
  • 3 to 5
  • 5 to 8
  • 8 to 15
  • 15+
  • If You Also Use Kiosks
  • 1 station or 1 kiosk
  • 1 kiosk plus 2 stations
  • 2 kiosks plus 3 stations
  • 2 to 4 kiosks plus staff
  • 4 to 8 kiosks plus staff
  • 8 to 12 kiosks plus staff

This table is a helpful guide, but it’s not a one-size-fits-all rule. As Valentina Ruffoni, Founder of People in Events, told us in a recent conversation:

Once your event is over, review what worked and what didn’t, so every event becomes smoother than the last.

The Benefit

You avoid bottlenecks by matching staffing and stations to real demand instead of assumptions.

5. Evaluate Facial Recognition Carefully

Why This Matters

Facial recognition can speed up check-in dramatically, but it is not universally allowed or appropriate.

How to Approach It

Check regulations in your region, review consent requirements, assess comfort levels of your audience, and ensure your tech provider complies with the necessary standards.

The Benefit

When used within the right context, it delivers a quick and touch-free check-in experience. Event planners use it to deliver a cutting-edge experience to attendees that speaks luxury from the get-go.

Why This Might Not Work

Some countries restrict biometric data use. Some audiences do not feel comfortable with it. In these cases, use fast scanning or RFID as alternatives.

6. Train Your Staff and Build Tech Familiarity

Why This Matters

Even the best tech does not help if staff are unsure how to use it. Hesitation at the scanner slows everything.

How to Approach It

Hands-on training is non-negotiable. Andrew Roby walked us through his proven training approach that gets staff confident and ready:

  • Cover the Complete Check-In Process: Start by walking your team through the entire check-in procedure from start to finish. Even if staff have used your event tech before, make sure they’re working with the most updated version. Don’t assume familiarity. Tech updates can change workflows.
  • Go Deep on the Backend: Show your team how the registration system works behind the scenes. They need to understand not just how to scan a badge, but how to navigate the backend when issues arise. Run through actual check-in scenarios so they experience what they’ll encounter during the event.
  • Get Hands-On with Hardware: Give everyone practice time with scanners, printers, and any other equipment they’ll use. Make sure they know how to troubleshoot common hardware issues and understand your backup procedures. Equally important: ensure they know who to contact if something goes wrong.
  • Teach Strategic Line Management: This is where good training separates from great training. Show your team how to handle multiple attendee types without creating additional lines. 

The goal is to help attendees with issues without disrupting the flow for everyone else.

  • Include Scenario-Based Training: Walk through real situations they’ll face:
    • How to quickly redirect unprepared guests
    • How to identify the correct line based on ticket type
    • How to manage guests who arrive with no ticket
    • How to handle peak surges calmly
    • How to switch to backup processes if needed
  • Allow Time for Questions and Practice: Andrew’s team allocates roughly 30 minutes for training, with flexibility for those who need more time to get comfortable. Don’t rush this; confidence comes from practice, not pressure.
  • Debrief After the Event: Once registration wraps up, gather your team and review what worked well and what could improve. This feedback loop makes your next event even smoother.

The Benefit

A confident team keeps the line moving smoothly and can adapt quickly when issues arise.

7. Plan for Tech Failures

Why This Matters

No system is immune to WiFi drops, device glitches, or printer issues. A backup plan avoids panic.

How to Approach It

The best way to handle tech failures is to prevent them before they happen. Here’s the approach Valentina shared with us to deal with such problems: 

  • Communicate with Venue and Tech Providers Early: Valentina emphasised not waiting until event day to think about what could go wrong.
    You should talk to your venue and tech providers well in advance. Walk through potential failure points together, like unreliable WiFi zones, power outlet locations, device compatibility issues, and address them before they become problems. This advanced coordination can prevent most tech failures from happening in the first place.
  • Build Multiple Layers of Backup:  Valentina told us, “We would also have back-ups of everything, and as a last resort, a master list of attendees we can use to check people in if needed.”
    According to her, your backup strategy should include:
    • Spare devices (extra scanners, tablets, printers)
    • Offline scanning modes that work without internet
    • Mobile hotspots for WiFi backup
    • Pre-downloaded attendee lists
    • Manual check-in templates as your final failsafe

The Benefit

Even if something breaks, the line never stops. Attendees barely notice the switch.

8. Share Pre-Event Guidelines with Attendees

Why this Matters

Attendees walk in with different expectations and levels of preparedness. Some have their QR code ready. Others start digging for emails the moment they reach the scanner. This inconsistency slows everyone down.

How to Approach It

Send a simple pre-event email that shows exactly where to go, what to have ready, and how the scanning process works. Include visual cues or a short video if possible.

The Benefit

Prepared attendees move quickly through the line. Unprepared attendees know what to expect and are less likely to freeze at the front.

Key Actions to Take During the Event

Once you have planned your flow and chosen the right technology, the next step is setting up the physical environment where everything comes together. 

On-site setup determines how easily guests understand where to go, how quickly lines move, and how confidently your staff operates. A good setup removes hesitation, which is the biggest reason lines slow down.

1. Signage and Instructions

Why This Matters

People move faster when they know exactly where they belong. Without clear instructions, they stop, ask questions, or join the wrong line, all of which slow down everyone behind them.

How to Approach It

Place visible signs at the entrance and throughout the waiting area. Use simple labels like “Printed Tickets,” “Phone Tickets,” “Walk Ins,” “VIP,” or “Self Check In.” Add arrows or floor markers so people keep moving in the right direction.

The Benefit

Guests instantly understand where to stand, which reduces confusion and keeps the flow smooth and predictable.

2. Infrastructure and Stations

Why This Matters

Even with great technology, a poorly arranged check-in area creates congestion. The physical layout decides whether people move freely or get stuck in crossing paths.

How to Approach It

Set up scanning stations with enough space between them. Position badge printers in a way that prevents people from crowding. Place kiosks slightly away from staff-operated lines so both can operate independently. Ensure each station has power, stable devices, and a clear path for guests to exit.

The Benefit

Your check-in area feels organised, connected, and efficient, allowing both staff and attendees to move without friction.

3. Segment Attendees by Ticket Type

Why This Matters

Different guests arrive with different levels of readiness. Mixing them in one line slows down the entire group.

How to Approach It

Create separate lines for printed tickets, mobile tickets, and people who lost or cannot find their ticket. Each line moves at a different speed, so separation prevents fast-moving guests from getting stuck behind slower processes.

The Benefit

Guests who are ready move quickly, and guests who need help receive it without holding others back.

4. Active Line Management and Distribution

Cadence event

Why This Matters

Attendees naturally flock to the first line they see, and certain ticket categories can swell unexpectedly. Without intervention, this creates uneven distribution and unnecessary bottlenecks, leaving some staff overwhelmed while others stand idle.

How to Approach It

Assign a dedicated “traffic controller” at the entry point to guide guests evenly across all stations. This staff member should not only direct initial flow but also monitor the lines (visually or via check-in analytics). If one line stagnates or grows too long, they must make quick decisions to redirect guests to emptier stations or open backup lanes.

The Benefit

Every station stays active, every scanner stays busy, and the entire check-in process moves faster overall.

5. Remind Attendees About Their Tickets

reminding attendees about their tickets

Why This Matters

Many people join the line without their QR code or printed ticket ready. They often remember only when they reach the front, which creates sudden stops.

How to Approach It

Have roaming staff or volunteers remind guests to open their ticket, increase screen brightness, or pull out their printed pass while they wait. This tiny action saves significant time at the scanner.

The Benefit

More people arrive at the scanner fully prepared, which increases overall speed and reduces micro delays.

6. Keep the Scanning Line in Constant Motion

Why This Matters

Momentum is everything during live check-in. Once the line slows or stops, frustration builds quickly.

How to Approach It

Ensure scanners stay active at all times. If one station faces a delay, staff should redirect those behind the stalled guest to the next available scanner. Staff should also immediately move unprepared guests to the side area so they do not block the flow.

The Benefit

A constantly moving line reduces perceived wait time and creates a positive first impression for attendees.

7. Assist and Pull Aside Stalled Guests

Why This Matters

One confused or unprepared attendee can slow down dozens of people behind them. The key is addressing issues without sacrificing flow.

How to Approach It

Train staff to politely move stalled guests to the side, assist them, and return them to the line once ready. Use a designated help desk or support area for walk-ins, lost tickets, or mobile access problems.

The Benefit

You maintain a fast-moving line while still giving personal attention to guests who need help.

Key Actions to Take After the Event Ends

Once your event wraps up, your check-in strategy is not finished. The post-event stage is where you uncover what worked, what slowed things down, and what should be improved for next time. 

Modern event technology gives you powerful analytics to understand attendee behaviour, peak times, and overall entry efficiency. Reviewing this data turns every event into a learning opportunity.

1. Track Key Event Check-In Metrics

Why This Matters

Data takes the guesswork out of check-in. Instead of relying on assumptions, you’ll clearly see what worked, what didn’t, and how efficiently your entry setup handled real attendee flow.

How to Approach It

Here are all the key metrics you should be reviewing:
Check in speed: How fast were guests processed at different times and stations?
Peak entry times: When arrival surges happened, and whether your setup handled the volume.
Attendee satisfaction: Gather feedback through surveys to understand how guests felt about the entry experience.

The Benefit

You build a clear performance picture instead of relying on memory or assumptions.

2. Combine Data with Attendee Feedback

Metrics tell you how your check-in performed, but they don’t always show how it felt for attendees. A line may move quickly, but if it looks long, it still creates frustration, and that emotional impression can shape how people remember the entire event.

The takeaway is simple: data is critical, but it becomes powerful only when paired with real attendee feedback. Balancing numbers with observation helps you understand the full story, not just how fast you checked people in, but how your arrival experience made them feel.

3. Use Data to Improve Future Check-In Performance

Why This Matters

Insight only matters if it turns into action. Data and feedback show exactly what needs upgrading, adjusting, or rethinking.

How to Approach It

Here’s how you can leverage data and attendee feedback to make informed decisions:

Continuous monitoring: Track data in real time during the event so you can open more lines or shift staff instantly.
Integrate systems: Connect ticketing, check-in, registration, and analytics so you get a complete view of attendee movement.
Compare across events: If your event repeats, use year-over-year or show-over-show comparisons to refine forecasting.

The Benefit

Each event becomes easier to plan, more predictable, and more efficient than the last.

4. Apply What You Learned to Future Events

Why This Matters

Every event gives you clues about what your next check-in should look like. Use that insight to make better decisions and design a smoother entry flow.

How to Approach It

  • Optimise staffing: Increase support during peak times or add more scanning stations.
  • Upgrade technology: Expand the use of tools that proved fastest, such as badge printing, kiosks, or RFID.
  • Listen to attendees: Use their comments to improve clarity, signage, or line structure.

The Benefit

Your entry process gets stronger every year, creating a consistently smooth and reliable check-in experience.

Bring It All Together With a Smart, Tech-Driven Check-In Strategy

A smooth check-in experience does not happen by chance. It is the result of clear planning, the right technology, smart onsite setup, and confident live execution. When each part works together, your entrance becomes fast, predictable, and stress-free for both guests and staff.

FAQs

How many event check-in stations do I actually need?

Base this on peak arrival volume, not total attendance. A good guideline is one staffed station for every 100 to 150 guests arriving within the same 30-minute window.

What is the fastest event check-in method available?

QR-code based check-in systems are the fastest. For most events, a combination of QR scanning and onsite badge printing offers the best balance of speed, flexibility, and ease of setup.

Should I pre-print badges or print them onsite for event check-in?

For smaller events, pre-printing can work. For medium or large events, onsite printing is significantly faster because it eliminates badge sorting and supports instant updates and walk-ins.

What should I do if my audience is not tech-savvy during event check-in?

Use more staff-assisted stations and keep kiosks optional. Provide simple signage, easy instructions, and support for printed tickets. A dedicated help area for walk-ins or lost tickets prevents slowdowns at the main line.

How do I prevent attendees from crowding into one line during event check-in?

Assign a line manager at the entrance to distribute people evenly. Most guests join the first line they see, so human guidance is essential for balanced traffic.

What happens if the Wi Fi drops during event check-in?

Choose a check-in system with an offline mode so scanning continues even without internet. Keep backup hotspots available and ensure one device stays synced for data recovery.
