Access Control vs Membership SoftwareOne opens the door. The other decides who's allowed through it.

Why isn't access control enough on its own?

Access-control systems manage credentials, not relationships. They can tell you a code opened door 1 at 6:04am; they can't know that the person holding it cancelled last month or that their card failed on Tuesday. Somebody has to tell them, and if that somebody is a person with a spreadsheet, it doesn't happen reliably.

Why isn't membership software enough on its own?

Because it can't open a door. It knows exactly who's current and who booked what, and none of that reaches the lock unless something carries the message.

What does connecting them actually change?

Access becomes a live function of payment and booking status rather than a manual list. A lapsed membership revokes itself, a refunded booking kills its code, and a new member's credential exists the moment they sign up — with no one maintaining anything.

• Automatic revocation. Cancellation or a failed payment ends access without a person acting.
• Per-session codes. Pay-per-visit customers get a code scoped to the window they paid for.
• One entry log. Entries reconcile against members and bookings instead of anonymous PINs.
• One bill. Facilities commonly pay separately for an access subscription and a member system.

Do I have to replace my access hardware to connect them?

Usually not. Most cloud-managed commercial controllers expose an API that can create and expire credentials, which is all the connection requires — the keypad on your wall stays where it is.

Cinch issues the code. Delivering it to your specific door controller is integration work we scope and confirm before you sign — not a checkbox we pretend is already ticked. Most cloud access controllers (infinias / 3xLOGIC, and others in that class) publish an API for doors, people, and PIN credentials, which is all a per-session code needs. If yours doesn't, we'll tell you that on the first call rather than after the contract.
