What is Guest Data Capture?
Guest Data Capture is the CaptiFi feature that turns a WiFi login into a customer record. When a guest connects, the branded splash page asks for their name, email and marketing consent, and the guest database grows with every connection, with no forms for staff to fill in and no cookies or third-party tracking. It is for any venue with visitors it cannot currently contact. Included on every plan, from Essentials up.
Before, and with CaptiFi
Before
Most venues have hundreds of visitors per day but capture zero contact details. You're sitting on a goldmine of potential repeat customers, but they walk out of the door anonymously.
With CaptiFi
CaptiFi captures guest email addresses, names, and marketing consent at the moment of WiFi login. Your database grows automatically with every connection, with no staff training needed.

Build a verified first-party email list without cookies or third-party tracking
Capture guest details at the moment of WiFi login, with zero manual effort
GDPR-compliant consent collection built into every login flow
Average 40-60% email capture rate across all venue types

Every guest has a story
Open any guest and you see their visit history and how they have engaged with your messages. Regulars, lapsed guests and first-timers become obvious, which is exactly what win-back and loyalty campaigns need.
- Visit history per guest
- Engagement at a glance
Every field is a choice, and consent is never assumed
| Field | Default | What it is for |
|---|---|---|
| Name and email | On | The standard sign-in. Email is what campaigns, review requests and integrations key on. |
| Marketing consent | On, asked separately from getting online | Stored per guest with an audit trail. Only guests who accept are emailed; where the SMS opt-in box is on, texts go to guests who tick it. |
| Phone number | Optional | A ready-made field with a country-code picker, for SMS marketing under the same consent. |
| Date of birth | Optional, minimum age 13 to 25 | Powers birthday messages and age-gated venues. Guests under the minimum cannot submit the form. |
| Your own question | Optional | How did you hear about us, table number, anything. Answers become a column on the guest list. |
| Visit history | Automatic | Every return is recorded against the profile without a form, because the device is recognised. |
How to capture guest data through WiFi with CaptiFi
Four steps from an unboxed device to a list that grows on its own.
-
1
Connect your access points
Plug in the CaptiFi starter device, or point your existing UniFi, Omada, Aruba, Meraki, Cisco, Ruckus, MikroTik or Fortinet FortiAP network at CaptiFi following the setup guide for your hardware.
-
2
Choose what to ask for
In the splash builder, switch on the fields you want: name and email as standard, a phone number for SMS, a date of birth with a minimum age, or your own question. Leave marketing consent on: guests are asked separately from getting online, on the standard sign-in page as a question after they tap Connect, with Accept and Reject buttons, and those who decline still get online.
-
3
Publish the splash page
Save the design and it goes live on the venue WiFi. Guests joining the network see your page, fill in the form and connect. Returning devices are recognised and let straight through.
-
4
Watch the list grow
Every sign-in adds a guest to your database with their consent recorded. Filter, segment and export as CSV on any plan, or push to your email platform from Growth.
What is guest WiFi data capture?
Guest WiFi data capture is the practice of asking a visitor for their details on the WiFi login page, the captive portal, in exchange for access. Done properly it produces a first-party marketing list: every contact came from someone who physically visited, gave their details themselves, and answered a separate question about marketing. CaptiFi runs the login page, stores each guest with their consent, recognises them when they come back, and hands the list to your campaigns, review requests and integrations.
Why first-party data matters more than it used to
The contacts a venue owns outright are the ones it can reach next month without paying a platform for the introduction. A WiFi list is first party by definition: the guest was in the building, the consent is recorded, and nobody else can switch it off.
How is this different from a QR code or a paper form?
The guest already wants the WiFi, so the form is on the path they were going to take anyway. A QR code on a table asks for a detour, a paper form asks a member of staff to type it up later, and neither records a return visit. The WiFi login does all three without anyone on the floor doing anything.
CaptiFi is a guest WiFi marketing and captive portal platform for restaurants, bars, pubs, cafes, hotels, gyms, salons, retail and short-term rentals, built by CaptiFi Ltd in the UK and sold in GBP, USD, EUR, CAD, AUD and NZD to venues worldwide.

CaptiFi completely changed my business. Before, every guest was a one-time booking. Now I have a direct line to thousands of people who've stayed in the plane. I can offer them return deals, send updates about new features, and keep them engaged. My repeat booking rate went from almost zero to 35%. It's been incredible.
