QR at the door, RFID on the card, records in your account.
People scan a single-use QR code on their phone or tap an RFID card, and the entry and exit records land in the system at once. Because each code works only once, a screenshot cannot get anyone in.
Does this sound familiar?
Cards change hands
Someone lends a card to a colleague and an entry is logged in their name without anyone noticing.
Attendance is written up afterwards
Sign-in books and sheets are unreliable and correcting them takes time.
Unusual entries go unnoticed
Nobody notices that a door was opened at midnight, not even the next day.
How Kurumca solves it
Single-use QR codes
The code is signed by the server and works once, so screenshots and copies are useless.
RFID card and PIN
For people who cannot use QR there are RFID cards and PIN entry too.
Raspberry Pi and ESP32 terminals
Terminals at the door stay in live sync with the main system and you watch their status from the panel.
Alerts for unusual entries
Unusual attempts are scored and flagged, and everything is written to the log.
