The door is part of the software.

Most gym systems log who walked in. Gym Stack 360 decides whether the barrier moves — with a credential that expires before it can be shared, a lane you can fire from your office, and a wizard that walks your electrician through the install and won't let you sign off until six tests pass.

The credential

A code that expires before it can be shared.

Card sharing is the oldest leak in the industry, and a static QR code on a screenshot is worse than a card — it copies perfectly and travels by message. Every code Gym Stack 360 issues is signed, lives for thirty seconds and works exactly once. Screenshot it and the lane refuses it. Hand your phone back over the barrier and the second scan is refused too.

  • Thirty-second life, single use — a passed-back phone or a forwarded screenshot buys nobody a workout
  • Signed with a key that is yours alone — a reader lifted off the wall gives an attacker nothing they can forge with
  • Revoke a member instantly — the next code refuses to issue and the app tells them to see the front desk
  • Codes arrive in batches — the phone isn't waiting on a network round-trip at the barrier with a queue behind it

The lane

Every barrier you own, on one screen.

Each lane is a row in your settings: which location it belongs to, which way it turns, how long it stays open, and whether it is the accessible route. A relay behind it does the actual work, and you can fire it from your desk without walking to the door.

  • Test pulse from the dashboard — prove a lane works without a member standing in front of it
  • Per-lane health built from the last 24 hours of failed fires, so a dying lane announces itself
  • Entry, exit or both per lane, with the pulse length tuned to your turnstile
  • “Why was Marie refused at 6:04?” is one click — every decision and its reason is in the activity log

The wizard

Six steps from “we have a turnstile” to a lane that works.

Access control normally means a site survey, an integrator and a quote with a comma in it. This is a wizard in your settings that asks five questions, works out what your site needs, and produces the paperwork your electrician actually wants.

1

Site

Five questions: do you have a turnstile, what make is it, how is the site staffed, what network reaches the lane, and is there a wheelchair-passable route.

2

Tier

It derives what your site needs and shows its reasoning. You never pick — and if the honest answer is “you don't need this”, it says that instead of selling you something.

3

Install pack

A branded A4 PDF for your electrician: parts list, wiring sheet, the fire-circuit boundary in bold, and a photo request for the terminal block.

4

Lane

Name it, pick the location and direction, flag it if it is the accessible route, set the pulse length for your barrier.

5

Tablet

Type a pairing code once on the kiosk. It keeps its own token from then on — no login, no password on the front desk, nothing to leak when a staff member leaves.

6

Commission

Six recorded tests, written down as they are answered. One failure blocks sign-off. Nobody gets to tick “it seemed fine”.

The install pack

Paperwork your electrician will actually open.

You download the pack and forward it from your own address — the one your electrician already invoices. A PDF arriving cold from a software company they have never heard of is a phishing-shaped object that gets filtered or ignored, so we don't send one. There is a paste-ready note to go with it, naming the two things most likely to go wrong on the day.

  • Parts list with the exact relay — about €14 of hardware per barrier, not a five-figure integration
  • The dry-contact spec every turnstile understands, per direction
  • The fire-circuit boundary in bold — we are never in your emergency release path, and the sheet says so
  • A photo request for the terminal block — so the next lane you add is easier than this one

Straight answers

What we won't sell you.

Access control is the one part of a gym system that fails in front of a queue. Here is exactly where ours stops, in writing, before you buy it.

It needs your internet up

A scan is checked by our servers and the relay is fired over the network. If the line at that site is down, the barrier does not move and your staff wave people through. That is why the wizard asks how the site is staffed before it lets you buy anything.

Unstaffed sites get told no

If your gym runs unattended hours, the wizard refuses the standard setup and explains why, then offers to put you on the list for the always-on tier that verifies at the lane itself. We haven't shipped that yet. There is no “continue anyway” button, because a site that needs it would be the first to be let down.

We are never in the fire path

Nothing we install sits in your emergency release. It is in the install pack in bold, it is one of the six tests, and the installer signs their name against it. Your fire strategy stays your fire strategy.

A tripod lane can't be the only way in

The wizard asks whether you have a wheelchair-passable route, warns you if you don't, and makes you prove that the very same member code opens the wide lane. Nobody should have to ask staff for a key to get into a gym they pay for.

Everything included

Access Control capabilities, in full.

Rotating QR credential

Signed, single-use and expiring — a screenshot is worthless and a passed-back phone opens nothing.

PIN as the fallback

Flat battery or phone in the locker? A rotating front-desk PIN gets them in without a queue forming.

Relay per lane

A valid scan pulses the barrier. Pulse length, direction and location are set per lane, per turnstile.

Commissioning wizard

Six recorded tests and a named sign-off. One failure blocks completion — no lane goes live on a maybe.

Install pack PDF

Branded, download-only, written for an electrician who has never heard of us. Forward it from your own inbox.

Kiosk that stays up

Pairs once, then keeps its own token. Survives reboots and staff turnover with nobody logging in.

Lane health & test pulse

Fire any barrier from your desk, and see the last 24 hours of failed fires before a member does.

Access windows at the door

Off-peak plans are enforced by the barrier, not by a conversation at the front desk.

Every decision logged

Granted, refused and why — per lane, per member, per minute. Disputes end in one search.
