Door Communication: Gira Keyless In The Gira Keyless In keypad opens the door for authorized persons when they enter a personal numeric code. Lightly touching the code keypad is sufficient. The Gira Keyless In transponder is based on a long-range transponder. Since the transponder key transmits a signal automatically as soon as it detects the reader, it does not actually have to be held in front of the field but can simply remain in your pocket. The Gira Keyless In fingerprint sensor controls access using the biometric properties of the fingerprint.
