NSP’s Mobile Access, using Bluetooth Low Energy (BLE) allows doors to be opened with a smartphone, potentially removing the need for a card or fob. NSP’s Mobile Access securely issues, revokes the access rights you grant your users, and the access can be delegated across NSP range of RFID control readers throughout your accommodation facility or commercial premises in the same way a traditional Access Control System would be managed. The NSP App will collect data from each Electronic Lockset that logs each ‘event’ from each door, which is transmitted from the User’s phone to the server – safely and securely updating the controlling PC in real time. The NSP Mobile Access System is controlled by each user / Resident via the NSP Mobile App (Application) which is user friendly, intuitive, and can be incorporated in to an existing App if where required.
