A fitness club with 900 members and a front desk staffed from seven to nine. Outside those hours the door is locked, even though a share of members would rather train precisely then. The owner wants longer opening hours without rostering another member of staff — and certainly not without knowing who is inside. That is almost always the real question behind “gym access control”: not which reader goes on the wall, but how much desk time it costs and how much control you get back.

Opening the door is the easy part. Every reader, gate and turnstile on the market does that reliably. The problem sits a layer deeper: keeping the list of who may enter aligned with the list of who is actually paying.
Every club knows the pattern. Someone cancels, but their fob keeps working until somebody remembers to deactivate it. A member pauses with an injury and access simply carries on. A direct debit fails and nobody notices until the month-end close. None of these is a fault — each is a case of two systems that know nothing about each other drifting apart: your membership administration and your access system.
That is the yardstick to hold the options below against. Not “does the door open”, but “how often does a human have to step in to keep the list correct”.
In practice almost every fitness club controls access in one of five ways, or some combination of them.
1. Fob or card. The member holds a card or tag to the reader. Works without a phone and without internet, and members know it. Downside: fobs get lost, break and get lent out. Every replacement costs both a fob and a conversation at the desk.
2. QR code on the phone. The member receives a personal code on joining and scans it on arrival. There is nothing to hand out and nothing to replace: lost means a new code in a single message. Downside: the member needs their phone at the entrance.
3. Licence plate recognition (ANPR). A camera reads the plate in the car park and opens the barrier. Fully hands-free, and it handles parking and access in one movement. Downside: it only works for members who arrive by car — at a city-centre club that is a minority.
4. PIN code. The member types a code. No hardware needed on the member’s side. Downside: codes get passed around, and most systems cannot revoke one member without changing the code for everybody.
5. Front desk. A staff member checks each person in by hand. Personal contact and direct control — and precisely for that reason the most expensive option, because it costs staff during every hour the club is open, quiet ones included.
The purchase price of a fob is rarely the point. Work it through for your own club. Take 900 members and assume one in seven loses or replaces their fob each year. That is roughly 130 replacements. If each one takes five minutes of desk time — look up, issue, pair, block the old one — you are spending close to eleven hours a year on a task nobody considers a service.
Those numbers are a worked example, not an industry figure; fill in your own. The point is that the cost of fobs sits almost entirely in desk time rather than in the fob, and that this time lands exactly when reception is already busy.
On top of that comes the lending problem. A fob is tied to a piece of plastic, not to a person. Whoever lends one out gives a second person access on a single membership, and the reader cannot tell.
Whichever of the five you choose, the difference between a system that costs time and one that gives it back comes down to a single question: is access linked live to your membership administration?
Without that link you maintain two lists by hand and structurally run behind the facts. With it, the following happens by itself:
Revtek connects to systems such as Virtuagym, Perfectgym, SportBit Manager, eGym, Technogym Mywellness, Fitmanager and Mindbody — and in principle to any membership system with an API. You keep managing members where you do today; access follows.
The question “can we open 24/7” rarely fails on technology. It fails on the question of who is inside when no staff are present, and whether you can demonstrate that afterwards.
That is solvable by recording every entry at member level: name, time, access point. After an incident you can see who was in the building. A code tied to one membership that expires on use solves the lending problem a fob creates. And an alert on exceptions — a door held open too long, a repeated refused entry — means you only hear about what deviates.
In practice that is the difference between “we daren’t open unstaffed” and a club running from six to midnight on half a day of cover.
Access logs are personal data: they show where an identified person was at a given moment. That means you need a lawful basis, a retention period and a data processing agreement.
Practically: record why you keep the logs (access security and member safety), set a retention period that matches rather than keeping everything indefinitely, and make sure your supplier signs a processing agreement. If you use WhatsApp to communicate with members, do it through the official Meta Business API rather than a staff member’s personal phone — the latter is not processing you can account for.
A few rules of thumb that hold in most clubs:
What works in none of those scenarios is an access system that knows nothing about who is paying. That is not access control — it is a door with an extra step.
