A new mobile key app called JustIn launched by Salto will enable hotels guests to receive their keys online.

The intuitive JustIN mobile key app, developed by Salto, communicates securely via the cloud and enables a hotel guest to receive his room key online. For the guest, the process is as simple as arriving at the hotel and deciding to receive the room key directly to his smartphone (iOS and Android devices) without going to hotel reception for the traditional check-in process.

Salto mobile key works across the Salto product range including XS4 and AElement electronic locks collections. To use Salto's mobile key solution, no special software is required and it combines Ultralight C, Desfire EV1, Mifare Plus, Bluetooth, and NFC technologies into one secure package. A Salto mobile key cannot be duplicated, unlike mechanical keys or some RFID technologies, and its encrypted data transfer uses SSL AES 128 bit encryption opening procedures.

For the hotel, using Salto mobile key is very simple. An operator just needs to open Salto's ProAccess Space software for hotel access management and go to the check-in menu. From the main screen, choose a room and date, enter the new guest's mobile phone number and press ‘edit key’ to send the guest key his room.

From the operator's side software shows, a confirmation message on the screen confirming that a new key has been sent to the selected guest's smartphone, and that the guest has received the key. The guest then opens the Salto JustIN key app on his phone and taps the start button displayed on the app. The app then prompts the guest to present his phone to the room lock whereby the lock and mobile key instantly verify access with each other, and the lock opens permitting the guest to enter his room.
