SALTO uses RFID and NFC technologies which are both R&W (read write) technologies. In addition, SALTO by default incorporates data-on-card SVN (SALTO Virtual Network) technology into all locks to ensure that access is never compromised.

SALTO’s unique system offers stand-alone, networked and wireless solutions. A data-on-card-card-based system that allows the lock and the card to communicate via SVN. SALTO is a true Read & Write (R&W) solution.

Such a system allows stand-alone locks to upload, store and download the latest access information as guests and staff use their RFID cards throughout the hotel. The cancelled key list is updated, key cards are cancelled and audit trail reports are downloaded via this wire-free environment. In summary, SVN technology gives the hotel additional security and operating benefits compared to standard hotel locking systems.
