Congress accreditation in Argentina without queues at the door

By SOMOS DER · October 30, 2026 · 7 min read

A queue at a congress is not solved by adding people at the door. It is solved by planning for the peak. Most attendees arrive in the hour before the opening session, so open check-in well before the program starts, separate the desk that scans from the desk that prints badges, give each attendee category its own registration link and keep one desk free for exceptions. This guide covers how to do that for a conference or medical congress in Argentina when you are organizing from abroad.

Argentina hosts many international congresses

If you are bringing a congress to Argentina, you are not alone. An official note from the national tourism office reported that, in the ICCA ranking for 2018, Argentina rose to 18th place among 200 countries with a record of 232 international congresses, and that Buenos Aires hosted 133 of them, first in the Americas for the tenth year in a row and 11th worldwide. Many of those meetings are run by scientific societies, and they share the same problem at the door: several audiences in one building on the same morning.

The problem is not volume, it is concentration

Take a congress of 800 people. It does not have an 800 person problem. It has a problem of, say, 600 people arriving between 8:30 and 9:15 because the first talk starts at 9:30 and nobody wants to miss it. If you size the door for the total, it looks fine on the spreadsheet and fails on the sidewalk.

So the first number to estimate is not how many will come, but how many arrive in the worst half hour. Desks, operators and printers all follow from that. The UK Health and Safety Executive's guidance on crowd management controls makes the same point for larger crowds: encourage "phased arrivals and departures", and where arrivals may exceed safe capacity, have "arrangements for monitoring and estimating the numbers of people arriving".

Open check-in before the program starts

The cheapest fix, and the least used: open the accreditation desk well before the first session and say so in every pre-event email. Each person who checks in at 8:00 is one less person in the 9:00 queue. A welcome coffee, breakfast or the sponsor area opening early gives people a reason to come.

On a multi-day congress, the hard peak is day one. From day two most people already have their badge and entry is lighter. You can reduce operators, but keep the exceptions desk: there is always someone who joins late or lost the badge.

One registration link per category, not a dropdown

A congress mixes general attendees, speakers, sponsors, exhibitors, press and staff. The clean way to handle them is a separate registration link per category instead of one form where people choose what they are.

In PASE, each attendee type has its own opaque link, and whoever registers through it lands in that category without seeing or choosing it. Nobody self-declares as VIP. Each person receives the QR code and the badge in PDF by email. The registration page and the QR email are available in Spanish and English: they follow the browser language, and adding ?lang=en to the link forces English, which is what you want for international speakers. There is no Portuguese version.

Ask only for what you need. Argentina's personal data law, Law 25,326, requires data to be "ciertos, adecuados, pertinentes y no excesivos" (accurate, adequate, relevant and not excessive) for the purpose they were collected for, treats health information as sensitive data, and states that no person can be obliged to provide sensitive data. At a medical congress, keep dietary or accessibility needs as optional fields that say what they are used for.

Split the desk that scans from the desk that prints

This is the most common mistake. Scanning a QR code is instant; printing a badge is not. If the same operator does both, the printer sets the pace of the whole queue.

Split the flow: one desk validates the entry, another hands over the badge. In PASE, when a scan comes back valid, a button appears to print that attendee's label, so the printing desk works in parallel without searching for anyone again. Speaker and sponsor badges can be printed in advance so they skip the general line.

Keep a desk free for exceptions

There are always exceptions: the person who did not register, the one who registered with another email, the speaker whose flight landed an hour ago and whose phone is dead. If the main line handles them, a two minute exception turns into twenty people standing still.

The PASE scanner has search by name to mark an entry without a QR code, and from the dashboard you can register someone on the spot and issue their code. Do that at a separate, signposted desk beside the queue, staffed by someone who speaks English if your audience is international.

Session rooms, sponsors and the live report

Not every room needs a scanner. Control the ones where the permission changes or where you need to know who attended: workshops with limited seats, sessions that count for credits, the speaker ready room or a sponsor symposium for a defined audience. In PASE that is the permission matrix: each attendee type is marked with the zones it can enter, and each room's scanner answers valid or not authorized on the spot. Rooms are set to re-entry, so a doctor who steps out for a call can come back in. Every controlled room is a check-in point: Base includes 1, Pro up to 4 and Enterprise unlimited, so a main entrance, two workshops and the speaker room already use four.

Sponsors who set up stands at 7:00 cannot depend on general check-in opening at 8:00. Give them their own time and entry point. PASE does not issue certificates; it records each entry with the time and check-in point, which is the base the committee uses for its own attendance certificates. Decide before the congress what counts as having attended, because it cannot be rebuilt afterwards.

During the event, the PASE live report updates by itself: how many are in, how many are missing, entries by hour and how many each gate processed. That lets you move operators while it still helps. If you load the venue capacity, PASE sends an email alert at 80% and 100%, and with a peak threshold it warns you when more people than expected enter within a 10 minute window.

Size the accreditation for the worst half hour, not for the total number of registrations. That is where the queue forms.

Frequently asked questions

How many check-in desks does a congress need?

It depends on the peak, not on the total. Estimate how many people arrive in the busiest half hour and split them across desks, with badge printing at a separate desk. If speakers, press or sponsors get different treatment, add a desk of their own.

Can I control access to session rooms and workshops, not just the main entrance?

Yes. In PASE each check-in point is set up separately: it can consume the pass (main entrance, once) or only validate it (rooms people walk in and out of). A permission matrix decides which attendee type can enter which zone.

What happens if two desks scan the same code at the same time?

Only one entry goes through. The entry is recorded atomically in the database, so the second scan is logged as a duplicate, together with the time that person had already entered.

Does PASE issue certificates of attendance?

No. PASE records who entered, at which check-in point and at what time, and delivers the attendance report and the closing report. The organizing committee uses that report to prepare and sign its own certificates.
