OFFLINE DATA-ON-CARD SYSTEM
The backbone of SALTO Space is the SALTO Virtual Network (SVN) data-on-card technology. SVN uses patented Data-on-Card technology to create a ‘virtual network’ where the users credential (eg. key card, fob or mobile phone) becomes a data carrier as users move through the building. Online access points are still required across key traffic-ways (such as the main entry), which download the full access list to every user’s card in real-time. When a user accesses an offline door, the door queries whether the user can open that door, and at the same time, writes that user’s audit and the battery status of that lock to the card. This allows an organisation to manage costs by fitting the majority of doors with stand-alone locks for situations where ‘almost real time’ will meet their needs.

ONLINE REAL-TIME SYSTEM
For facilities that need ‘real-time’, SALTO can add Bluetooth gateways that update the lock from the SALTO server. This way, the locks update, store and send the latest access information from the user’s credential throughout the building wirelessly and remotely. BLUENet can be used throughout or in select areas (with SVN in the rest).
In the event of a network failure, SALTO Space access control network continues to operate seamlessly via SALTO’s SVN data-on-card core technology. Additionally, any locks with the BLUENET feature-set can become SVN-Flex locks. SVN-Flex turns the lock into a wireless hotspot, enabling the locks to update access instantly in the way a hardwired point would. This way, access updates and validations can be performed at more points across the building. This enables a raft of access control features not previously attainable because of cost and complexity, such as instant credential updates and building-wide lockdowns.
