SALTO JustIN Mobile access technology simplifies the users and dynamic key management process of users in a building. Receiving a key generated electronically on their smartphone, previously identified and authorized by the system, they can unlock the assigned doors from the JustIN Mobile app by selecting the appropriate key.

Technologically cutting-edge, SALTO Mobile means the end of lost key hassles, expenses and waste. Plus, the technology isn’t limited to one building or hotel room -- it can also be used by the staff and users on multiple sites for any kind of access types like main entrance doors, elevators, car park barriers, meeting rooms, etc.

Combined with user-convenient features such as user friendly design or multi key possibilities to use the same app in different buildings, locations and for different applications, JustIN Mobile access control technology simplifies card issuing, fob and traditional pin code management that can be lost, forgotten or broken by offering flexibility for diverse applications. People do not forget their phones as they forget their keys and, if lost, they are replaced rapidly. This turns to be a major benefit for administrators, clients, and users.

Cool concept, but ...

I like the idea of using your phone as a room key.

One problem that I had with the app is that on the day of the checkout my key disappeared from the app. The checkout time was 11am, I returned back to my room from breakfast at 10am only to find out that the key has disappeared from the app, and I got locked out from my room. I had to go back to the reception desk to make a new physics key.

Another thought: would NFC be a better option instead of Bluetooth?

Great app!

Great app - the widget feature makes this quite convenient with few taps necessary to get to the key.

Two feature requests: 1) The ability to add a key to Apple a Wallet. 2)The ability to issue a key to a phone number that has not yet downloaded the app, so that when they do download the app and register, the key is there waiting for them.

Edit: Salto has addressed request #2. This is great! Now I’m just waiting for the ability to add a key to Apple wallet, and I’ll be over the moon!

Decent app, considering the limitations from Apple. I do wonder, is it possible to create a digital key in the “wallet” that would work both on the phone and the Apple Watch? This would be similar to how Apple is doing Express Transit or the newly announced digital car key.

This would allow for even quicker access and would not have the issue where when I hold the phone up the the NFC device it opens the wallet anyways. Maybe an integration like Walgreens has where the app knows which “card” to scan first for their rewards program.

I really would love Apple Watch support.
