What is digital event accreditation, and how it works at an event door in Argentina

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

Digital event accreditation is a system that registers attendees online, emails each one a unique QR code and validates access at the door by scanning that code in real time. It replaces the paper list: it identifies the person, stops the same pass from being used twice and leaves attendance data behind. In Argentina, acreditación is the everyday word for this whole process, from registration to the door.

If you are producing an event in Argentina from abroad, you will find that the local supplier, the venue and the client all talk about la acreditación as a separate line item. It usually means guest lists and invitations, not ticket sales: corporate events, congresses, trade shows, launches, press nights and parties with a closed list. This guide explains what the digital version does, step by step, and what it does not do.

How it works, step by step

1. Online registration. The attendee signs up on a registration page before the event.
2. QR code by email. They receive a unique code, with their badge in PDF.
3. Validation at the door. Staff scan the QR code with a phone camera or a scanner, and the system answers instantly whether the entry is valid, duplicate or not authorized.
4. Live data. As people come in, you can see how many have entered, by type, by door and by hour.

Each step has details that matter in practice, so it is worth going through them one at a time.

Registration: one link per attendee type

In PASE each attendee type has its own registration link: guests, press, speakers, staff, exhibitors, whatever your event needs. The person lands in the type of the link they used, so nobody picks their own category. That matters later, at the door, because the type decides where each person can go. The form also catches the typical email typos (gmial.com, hotmail.con) before it is sent, which prevents most of the "I never got anything" complaints.

The QR code and the badge

Every person gets their own code. If they lose the email, the "Recover my pass" page sends it again to the address they registered with. If the event has a start date loaded, PASE resends the QR code automatically 24 to 48 hours before, so the pass is at the top of the inbox when it is needed. The registration page and the email are available in Spanish and English, which helps when part of the audience travels in.

The door: three possible answers

The operator scans and the screen shows one of three results:

• VALID: the person is on the list and can enter at this point.
• DUPLICATE: that code has already been used. If two scanners at different doors read the same code at the same moment, one lets the person in and the other shows DUPLICATE.
• NOT AUTHORIZED: the person exists, but their type does not include this area. This is how a general guest is kept out of the VIP room without a separate list.

If someone arrives without their phone, the operator can search by name. Re-entry is configured per attendee type, or per check-in point in validate mode. Without re-entry, the code is consumed at each check-in point on first use.

Live data and the report afterwards

During the event you see real attendance growing, by type, by door and by hour. At the end there is a closing report to share with your client. Both are generated in Spanish, so if your client reads only English, plan for someone on your team to present the numbers.

What it replaces

Digital accreditation replaces the classic combination of a printed list, a pen and a visual check. The difference is not cosmetic: the paper list does not stop the same invitation from being used twice, does not record what time each person came in and, with volume, creates queues. The QR code solves all three. If you are deciding whether your event really needs it, see QR codes vs wristbands vs paper lists.

Concrete benefits

• Shorter queues: registration is already done, the door only scans.
• No double entry: each code is checked against all doors at once.
• Access control by area: each access type (general, VIP, press, staff) enters where it should.
• Data to make decisions: entry peaks, real attendance and post-event reports.
• No cost per unit: generating a QR code does not cost what printing a wristband does.

What you need

Less than it seems: a registration page, a system that issues and emails the QR code, and at the door a phone with a camera or a QR scanner with an internet connection. That last point is not optional: the check-in point needs internet. If the connection drops, PASE shows that it is offline and lets the operator retry, so it is worth testing the venue's signal or bringing a backup connection (more in what to do if the internet goes down at the door). If you want to choose hardware, see handheld scanner or phone camera.

If the event calls for it, you can add printed badges on site with a thermal printer, in several sizes, and operators at the venue.

What digital accreditation does not do

It is worth being clear, because in Argentina several services get bundled under the same word:

• It does not sell tickets. Paid ticketing is a different product. In our case, ticket sales are handled by ENTRÁ, from the same team.
• It does not do biometrics. No facial recognition: the door checks the code and, when in doubt, the operator can ask for ID.
• It does not assign seats or tables. That is handled with the floor plan and the reception team.
• It does not issue certificates of attendance for congresses or courses.

Two Argentine details to keep in mind

Personal data. Argentina has a data protection law, Law 25,326, which requires asking only for the data you need and telling people what it will be used for. A digital registration makes that easier than a spreadsheet emailed around, but you still have to decide what to ask. See what to ask in an event registration form and attendee data and Law 25,326.

Arrival habits. At many local events people arrive late and all together, which is exactly when a paper list collapses. A digital door does not make the rush disappear, but it turns each entry into a scan instead of a search.

Digital accreditation is not "putting a QR code on it". It moves registration to before the event so the door only has to validate.
