Onity announced it is supplying its DirectKeyTM mobile access solution to Hilton Worldwide, enabling guests to use their smartphone as their room key. The Onity DirectKey system uses cloud-based key credentialing and Bluetooth® technology to allow hotel guests to securely download their assigned key to their smartphone through the hotel’s loyalty app for easy access to their guest room and other access-controlled areas. Onity’s DirectKey credentialing technology provides a secure virtual key for Hilton hotel guests. The system activates an “unlock” button on Hilton HHonors members’ app screen when they are within close range of their door. By pressing the button, guests can gain access to their assigned room.
