QR access control for community pools
How to replace the lifeguard's paper list with one QR per household: capacity limits, guests with a cap, and scanning that works without coverage.
Every summer the same scene repeats at thousands of residential communities: the lifeguard with a printed list of residents, the queue at the gate while a surname is hunted down, and the eternal argument with whoever comes "on behalf of apartment 3B". The community pool is one of the few venues where access control ends up done by somebody hired for a different job.
The real problem isn't the paper: it's what paper cannot do
A printed list does not know how many people are inside right now, cannot tell a resident in arrears from one in good standing, cannot cap guests per household, and leaves no trace of anything. When the residents' association votes "maximum two guests per household and an 80-person capacity", paper has no way to enforce it.
How it works with QR
One code per household or per person. The property manager loads the list of households (a spreadsheet will do, or their own software through the API) and every resident receives their QR by email: on the phone, printed, or as an Apple Wallet pass. A resident who loses the email gets it re-sent in one click.
At the gate, any ordinary phone. The lifeguard or concierge scans with the scanning app. Green enters, red doesn't: no surname hunting, no arguments. If the community prefers full autonomy, the scanner can be an old tablet on a stand.
Capacity and "how many are inside". With entry and exit scans, the community knows live occupancy and can stop entries when the approved capacity is reached.
Guests, with a cap. Guest codes per household, with a limit. The end of "I'm with the family in 3B": either there is a code, or there is no swim.
Arrears and cancellations. If the association so decides, deactivating a household's QR is a switch in the dashboard — and reactivating it, another. No lists to reprint.
The detail that decides: coverage
Many community pools sit in basements, inner courtyards or residential developments where 4G barely reaches. This is where most systems fall over. The QRACCESS app also works offline: it validates against the downloaded list and syncs when coverage returns. The gate queue does not depend on the antenna — we wrote up how offline check-in works in detail.
What the community needs to start
The list of households (the property manager's spreadsheet). One Android/iOS phone or tablet to scan with, however old. Ten minutes to create the group and send the codes.
No turnstile, no building work, no dedicated hardware — although if the community already has a turnstile, it can be connected too.
What it costs
QRACCESS is paid per attendee, not per month: a 120-household community buys one pack and it lasts the whole season (and the next, while active balance remains). No winter fees with the pool closed. The concrete numbers are on the pricing page, and trying it is free with the first codes.
Managing several communities? Access control for venues covers the general case, and through contact we will set up the trial with one of your developments.
