✦ Smart locks

Get in without keys, whatever lock you have

WACheckin connects with your smart lock, generates a unique code for each booking and sends it to the guest at check-in. No handing over keys, no lockboxes and no waiting for anyone at the door.

From check-in to the door, without lifting a finger

When the guest completes their online check-in, WACheckin takes care of access from start to finish.

It generates the code on its own

Once the booking and check-in are confirmed, it creates a unique code for that stay on your lock. Each guest gets their own.

It sends it to the guest

The agent sends them the code and entry instructions on WhatsApp, in their language and just before they arrive.

It expires after check-out

Access is deactivated on its own when the stay ends. No lost keys and no codes left active.

✦ Frictionless access

Forget about keys, lockboxes and waiting around

No meet-ups to hand over keys, no lockboxes with the same code for everyone, no last-minute dashes. The guest gets in on their own, and you stay in control.

  • A different code for each booking, not a fixed one for everyone.
  • Remote access: open or revoke from your phone, wherever you are.
  • Check-in at any time, without depending on your schedule.
  • Everything tied to the booking: access starts and ends with the stay.
