QR attendance members can use without installing an app
GymNudge lets an authorised gym owner generate and print a QR attendance poster. A member scans it at the gym, enters the mobile number already on the gym's member list, confirms a masked name, and taps check in. The server verifies the active QR code, gym membership, and same-day duplicate rules before recording attendance for the owner to view.
The problem this solves
Attendance loses value when check-ins are slow, easy to duplicate, or disconnected from the member record used for renewal and retention follow-up.
- A paper register is difficult to turn into last-visit and inactivity context.
- Requiring every member to install another app creates avoidable friction.
- A public QR flow can expose member data if it is designed carelessly.
- Duplicate or expired-member check-ins make attendance unreliable.
How GymNudge helps
On plans where QR attendance is available, the owner generates one active QR code, prints the poster, and places it at reception. Regenerating it deactivates the previous active code.
The public flow returns only the gym name and a masked first-name/last-initial confirmation. It validates the phone against that gym, requires an active membership, limits repeat requests, and blocks a second check-in on the same Indian calendar day.
How it works
Owner generates the poster
An authorised gym user generates, downloads, or prints the active QR code from the attendance screen.
Member scans at the gym
The member opens the public check-in page without downloading an app or signing into the owner dashboard.
Member enters the registered mobile number
The server looks for an active member in that gym and returns only a masked identity for confirmation.
Member confirms check-in
The server revalidates the QR, member, active membership, and duplicate-day rule before writing attendance.
Owner sees attendance context
The recorded visit updates attendance views, last-visit information, and inactivity calculations.
What you can do
Printable gym poster
Generate, print, regenerate, or deactivate the gym's current QR code.
No member app required
Members use a browser form at the gym rather than installing an application.
Masked identity confirmation
Show enough of the name for the member to confirm without returning the full member directory.
Server-side attendance rules
Require active membership and prevent a second check-in on the same IST day.
Who it is for
- Growth and higher-access gyms using QR attendance
- Gyms that want browser-based member check-in
- Owners using attendance for retention context
- Reception areas with a printable poster
Who may need something else
QR attendance is not biometric access control, a turnstile integration, or proof that a person remained for a full workout. The public page is intentionally noindex and is not an SEO landing page for individual gyms.
Frequently asked questions
Who scans the QR code?
The member scans the poster at the gym and enters the mobile number already registered on that gym's member list.
Does the member need to log in?
No owner-dashboard login is required. The public flow verifies the active QR code and registered mobile number server-side.
Can a member check in twice in one day?
No. The server checks for an existing attendance record on the same Indian calendar day and blocks a duplicate.
Can the owner deactivate the code?
Yes. The owner can regenerate or deactivate the active QR code from the attendance setup screen.
