After-Hours Access Without Handing Out Keys: Phone, NFC and One-Time Passes

Owl Vision Solutions set up a low-cost membership access control system for a GTA business that needed to let customers in outside staffed hours: doors unlock remotely from a phone, one-time passes go to guests and cleaners, and members tap in with Bluetooth or NFC.

The situation

The client runs a membership-based venue and wanted members to be able to come in after regular hours without someone there to open the door, and without the cost of a big commercial access system. Handing out keys wasn’t an option: keys get copied, lost, and never come back when a membership ends.

What members and staff can do now

  • Remote unlock: staff can open the door from anywhere, for example when someone forgets their phone.
  • One-time passes: temporary codes for guests or cleaners that stop working after use.
  • Bluetooth and NFC entry: members tap or approach with their smartphone instead of carrying a card.

No complicated infrastructure: a reader at the door, an electric strike on the frame, and an app to manage who gets in and when.

Why this beats keys for small businesses

  • When a member leaves, you delete their access in seconds instead of changing the locks.
  • Every entry is logged, so you know who came in and when.
  • Cleaners and contractors get access only for the time they need it.

It works for gyms, studios, clubs, simulators, co-working spaces and small offices. Call (647) 588-9688 or request a quote.

Frequently asked questions

What is a one-time access code?

A code that works for a single entry or a limited window of time. It is useful for guests, cleaners and contractors, because you never have to hand out a key or share a permanent code.

Can the door be unlocked remotely?

Yes. The owner or staff can unlock the door from a phone app, for example to let in a member who forgot their credentials.
