ResDiary — Restaurant Reservations & CRM

WiFi logins linked to ResDiary.
Every diner profile enriched.

CaptiveWiFi pushes verified guest email addresses and visit data directly into ResDiary diner records. Returning guests are recognised, new guests are created, and tags — first visit, return, regular — are applied automatically.

How it works

Three steps to a complete
ResDiary diner profile.

1
Guest connects to WiFi
Your branded CaptiveWiFi portal captures name, email and marketing consent. No app required. The process takes under 30 seconds from the guest's phone or laptop.
2
CaptiveWiFi matches the ResDiary diner record
The verified email is checked against ResDiary. Existing diner records are updated with the new visit. If no match exists, a new verified profile is created automatically.
3
Tags and visit data written to ResDiary
Visit frequency, recency and guest tags — First Visit, Returning, Regular — are applied directly to the ResDiary diner record. Your team has the full picture next time they walk in.
Why CaptiveWiFi + ResDiary

ResDiary captures covers.
CaptiveWiFi captures people.

Reservations tell you who booked. WiFi tells you who actually came through the door — walk-ins, bar sitters, last-minute tables. Every one of those guests can be captured, verified and pushed into ResDiary without a single manual step.

Grow your ResDiary database automatically
Every WiFi connection adds a verified, opted-in diner to ResDiary. Walk-ins who never booked online become part of your CRM with zero manual entry.
Real visit frequency data in ResDiary
CaptiveWiFi tracks every WiFi visit and pushes frequency and recency data into ResDiary. Know which diners are regulars and which ones haven't been back in months.
First Visit, Return and Regular tags applied
CaptiveWiFi automatically tags guests in ResDiary based on WiFi history. Your front of house team knows exactly who is a regular before saying hello — no guessing required.

FAQ

Common questions about
ResDiary + CaptiveWiFi.

Does CaptiveWiFi work with walk-ins who never made a ResDiary reservation?
Yes — walk-ins who connect to WiFi get captured by CaptiveWiFi and pushed into ResDiary as new diner profiles. You don't need a reservation in place for the sync to happen. This means your ResDiary database grows with every visit, not just every online booking.
How does CaptiveWiFi match a WiFi guest to an existing ResDiary diner?
CaptiveWiFi uses the verified email address captured at the WiFi portal to look up existing ResDiary records. If a match is found, the existing profile is updated with the new visit data and any new tags. If no match is found, a new diner profile is created with the verified details.
What tags does CaptiveWiFi apply to ResDiary diner records?
CaptiveWiFi applies tags based on each guest's WiFi visit history. A first-time WiFi guest is tagged First Visit. Guests who return are tagged Returning. Guests who connect frequently are tagged Regular. Guests who haven't visited for a defined period are tagged Lapsed. All tagging is automatic — no manual input needed.
Is this GDPR compliant?
Yes. CaptiveWiFi only pushes guest data to ResDiary where the guest has explicitly consented at the WiFi portal. Every record includes a full consent log — timestamp, the exact opt-in wording shown and the guest's IP address. Marketing data is only shared for opted-in guests.
