The gate: signed QR codes that work offline

Residents invite from their phone and the visitor gets a QR code. At the entrance the guard scans it and the barrier lifts: no phone calls, no paper lists.

How it works

  1. The resident invites

    They pick the day, the time window and how many times the visitor can enter, and send the QR code by WhatsApp or email.

  2. The guard scans

    With a phone or tablet at the gate. The system checks the signature, the time window and the uses instantly, online or offline.

  3. It's on record

    The entry goes into the log and the resident is notified that their visitor has arrived.

What's included

  • Every QR code carries a digital signature with its time window and number of uses: it cannot be forged or reused.
  • If the internet goes down, the gate keeps validating and uploads the entries when the connection is back.
  • Frequent visitors with a permanent pass, and a record of every entry and exit.
