Handling Walk-Ins Without Breaking the Pre-Registered Flow
6 min read
A pre-registered delegate clears a lane in about ten seconds. A walk-in takes between ninety seconds and three minutes: name, company, phone, email, category, payment, verification, badge. That is a ten to twenty times difference in service time. Put both in the same queue and every pre-registered delegate inherits the walk-in's cost. The design problem is not how to register walk-ins. It is how to keep them entirely out of the fast path.
Isolate the slow transaction
Queueing behaviour is unforgiving here. In a shared queue, the average wait is dominated by the slowest transaction type, not by the most common one. If one in eight people at your entrance is a walk-in taking two minutes, the pre-registered majority behind them absorbs that delay in full.
So the first rule is physical separation, enforced by signage and a person, not by hope:
- Separate lanes with their own devices, their own printers and their own staff
- Separate physical positioning, ideally set back from the main entrance so a walk-in queue does not visually block the fast lanes
- Separate capacity planning, because walk-in volume is the number you know least about in advance
The second rule is to move the data entry off your staff and onto the visitor. A tablet-based self-entry form, in Hindi and English, with the visitor typing their own details, cuts desk time meaningfully and removes transcription errors. Your staff then verify and print rather than type. The person who knows the spelling of their own name should be the one entering it.
The third rule is to assume walk-ins are already in your database. At most Indian B2B events, a large share of walk-ins registered online, never completed, and turned up anyway.
Why separation matters
What the walk-in lane runs on
Self-entry on tablets
The visitor fills their own details in Hindi or English on a tablet while still in the queue, so desk time is verification and printing only.
Live deduplication on phone number
As soon as the mobile number is entered, the system checks the existing list and surfaces any partial or abandoned registration, so the visitor is claimed rather than duplicated.
UPI payment with instant reconciliation
Spot registration fees are collected by UPI QR with automatic matching to the registration record. GST invoices are generated and sent on WhatsApp.
Category rules enforced at entry
If your event restricts walk-ins to certain categories or caps their numbers, the rule is applied by the system, not by a volunteer making a judgement call.
Setting up the walk-in path
Estimate walk-in share from past events
Free-entry expos in India commonly see 15 to 35 percent walk-ins. Paid conferences see far fewer. Getting this within a reasonable band determines your lane count.
Cut the form to what you actually use
Every field costs roughly 8 to 15 seconds of queue. If nobody has ever run a report on the field, remove it. Designation and industry usually earn their place; postal address usually does not.
Decide the payment and invoice flow before the day
Cash handling at an entrance is slow and creates a reconciliation problem at night. UPI-first with a card fallback is faster and reconciles itself.
Give the lane a hard capacity signal
When the walk-in queue passes a set depth, an extra tablet and a second printer come online. The trigger is a number on the dashboard, not someone's impression.
Where this goes sideways
Duplicates are the durable problem. Someone registers online with one mobile number, arrives without their QR, gets registered again at the walk-in desk with a second number, and now exists twice. Your unique visitor count is wrong, your exhibitor lead data is polluted and the delegate gets two sets of follow-up messages. Phone-number-first matching catches most of this. It does not catch the person who genuinely uses two numbers, and no system will. We surface likely duplicates in a nightly merge report rather than guessing at the desk.
The second problem is that walk-in demand is not smooth. A local news mention, a free-entry announcement or a nearby event finishing can send an unexpected surge to a lane sized for a trickle. This is why the walk-in area needs physical space to expand into. Software scales in seconds; a two-metre-wide desk against a wall does not.
The third is consent. A visitor entering details on a tablet is giving you personal data, often under time pressure. The DPDP notice has to be on that screen, readable, in a language they use, with a genuine choice about whether their details are shared with exhibitors. A pre-ticked box on a tablet at a busy entrance is not consent, and it will not read well if anyone examines it later.
Questions we get asked
How many walk-in lanes do we need?
Take your estimated walk-ins for the peak hour and divide by roughly 25 to 30 completions per lane per hour with self-entry tablets. For 300 walk-ins in the peak hour, that is around 10 to 12 tablet positions feeding 2 to 3 shared printers. Fewer positions with self-entry beats more positions where staff do the typing.
Can we stop walk-ins entirely?
You can decline entry, but people will still arrive. Even a strictly pre-registered event needs a desk for the delegate whose registration failed, the sponsor's guest who was added by phone, and the speaker's colleague. Plan a small exception lane rather than pretending zero walk-ins is achievable.
Does the walk-in system work offline?
Yes for capture and printing. New registrations are written locally and synced when the network returns. Online payment is the exception, since UPI needs connectivity. For that case we record the transaction as pending and reconcile it once the network is back.
