Digital sign-in sheets: definition, obligations, and how they differ from check-in

One word, several realities

"We need a sign-in sheet." That sentence comes up in the planning of many professional events, but it covers very different needs depending on who says it. A training manager, a conference organizer, and the secretary of an association don't have the same underlying obligation — and therefore don't need the same tool.

Before picking a solution, it helps to clarify what "sign-in sheet" actually means, and what, in your specific case, is a good practice versus a legal requirement.

Sign-in sheet, check-in, attendance tracking: not the same thing

A signed sign-in sheet, strictly speaking, means a person signs a document to certify their presence. That signature — handwritten on paper or a legally equivalent electronic signature — gives the document evidentiary value: it can be used as proof in front of a third party (an auditor, an administration, a court).

Check-in or attendance tracking means recording the fact that someone arrived somewhere at a given time. A badge scan, a validated QR code, a box ticked on a list: these are timestamped records, useful for running the event day-to-day, but they don't carry the same legal weight as a signature — unless the system specifically includes a certified electronic signature.

The confusion often comes from everyday language, where "sign-in sheet" is used loosely to describe the whole process, including simple check-in — including in the title of this article, where the term is used in that broad, commonly understood sense.

When is a signature actually required?

Three contexts concentrate most of the regulatory sign-in requirements in France (and similarly in several other countries):

Continuing professional training. Training providers certified under quality frameworks (e.g. Qualiopi in France) must be able to prove that a training session actually took place, notably through proof of attendee presence. Depending on the framework and funder, this proof may need to be a signed sign-in sheet, including via a dedicated electronic signature system.

General assemblies. For co-ownerships, associations and companies, a signed attendance sheet at a general assembly is used to verify quorum and establish the validity of resolutions if challenged.

Certain public contracts or audits. When funding is conditional on proof that an event took place (a public meeting, a subsidized workshop), the funder may require a signed document.

Outside of these cases, most professional events — conferences, trade shows, seminars, corporate parties, product launches — have no legal obligation to have attendees sign anything. A timestamped, exportable check-in is more than enough to cover the real need: knowing who came, at what time, and being able to justify it internally.

What digital check-in delivers, without a signature

For the vast majority of organizers, what matters is not the legal value of a document but the operational reliability of the data:

• A reliable timestamp for each attendee's arrival (and sometimes departure), impossible to alter after the fact — unlike a paper list filled in at the end of the day
• An exportable report available right after the event, with no re-typing
• Real-time statistics: attendance rate, peak arrival times, comparisons across editions
• A searchable history for any question that comes up afterwards ("were they there at 2pm or only at 4pm?")

These cover most tracking, reporting and internal justification needs — without requiring a signature.

Comparison table

	Signed paper sign-in sheet	Timestamped digital check-in
Legal evidentiary value	Yes, if properly archived	No (unless a dedicated electronic signature is used)
Suited for	Certified training, general assemblies, audits	Conferences, trade shows, seminars, corporate parties
Speed at the door	Slow (one signature per person)	Fast (search or QR code)
Export and statistics	Manual, requires re-typing	Automatic, instant
Simultaneous multi-entrance use	Hard (a single physical sheet)	Native (shared real-time access)

How to decide for your event

Three questions are usually enough to know what you need:

1. Does a text, a quality framework, or a funder explicitly require a signature? If so, you need a proper sign-in system with a signature (archived paper or certified electronic signature) — a simple check-in tool is not enough.
2. Do you only need to know who came and at what time, for your own organization? A timestamped digital check-in fully covers that need, faster and more reliably than a paper sheet.
3. Do you need both? Some organizers combine the two: a signed sheet for the sessions subject to an obligation (e.g. a training morning within a larger event), and digital check-in for the rest of the program.

Gatesly is built for timestamped attendance tracking — list import, a QR code per attendee, real-time check-in and exportable reports — for conferences, trade shows and professional events with no signature requirement. See pricing plans →
