Preguntas frecuentes sobre JustIN Mobile

What happens if I change my phone number?

La aplicación no reconocerá el cambio automáticamente y podrás seguir utilizando la llave que está asignada a tu antiguo número.

Cuando el emisor de la llave asigne una llave a tu nuevo número, para poder utilizarla, tendrás que:

• Desinstalar la aplicación
• Descargarla de nuevo
• Inicia sesión con tu nuevo número de teléfono

What if my phone has no reception or is powered off? Will I get the updates?

La respuesta corta a esta pregunta es sí, pero hay que aclarar algunos puntos.

Cada llave enviada tendrá la misma duración que la fecha de caducidad de la actualización. Por ejemplo, si la llave de un usuario caduca en 8 horas, la correspondiente notificación de actualización se entregará en esas 8 horas. Sin embargo, si tu teléfono no tiene conexión a Internet o está apagado durante ese intervalo, el mensaje no se entregará. Incluso una vez que el teléfono se vuelva a encender o se active de nuevo la conexión a Internet.

Will I receive several updates once I switch on my phone?

No. No tiene sentido recibir varias actualizaciones, ya que la más importante es siempre la última. JustIN Mobile siempre recibirá sólo la última notificación de actualización desde la nube.

What happens if I lose or change my phone?

Si tienes una llave JustIN Mobile existente y pierdes o cambias tu teléfono, podrás recuperar tu llave en tu nuevo teléfono.

Sigue los pasos siguientes para recuperar tu llave:

• Descarga la aplicación JustIN Mobile en tu nuevo teléfono
• Inicia sesión con tu número de teléfono existente

Why do I see Apple Pay or "Payment card will not work" messages on iOS?

You may encounter the following Apple Pay-related behavior when using JustIN Mobile on iOS:

"Payment cards and passes in Wallet will not work automatically while "JustIN Mobile" is in use" message:

• The JustIN Mobile app disables Apple Pay while in use to prevent Apple Pay from appearing when you unlock doors
• This ensures a smooth unlocking experience without Apple Pay popups
• This only affects the main app, not widgets

Apple Pay popup with widgets:

• When using iOS widgets, Apple Pay may briefly appear because both features use similar technology
• This is normal and won't affect your unlocking or cause any payments
• The interference typically lasts only a couple of seconds

What's the difference between NFC and Bluetooth unlocking?

JustIN Mobile offers two main unlocking methods:

NFC unlocking (recommended when available):

• Fastest method - no need to open the app (although on iOS NFC tapping on a widget will open the app)
• Hold your phone close to the lock
• Available on all NFC-enabled Android devices
• On iOS: only iPhone XS+ with iOS 17.4+ in the European Economic Area (EEA)

Bluetooth unlocking (works on all devices):

• Requires opening the JustIN Mobile app first
• Tap the green unlock button and position your phone near the lock
• Works on all iOS and Android devices with Bluetooth

Why can't I use NFC unlocking on my iPhone?

NFC unlocking on iPhone has specific requirements:

• iPhone XS or newer model
• iOS 17.4 or later
• You must be located in the European Economic Area (EEA)
• JustIN Mobile app version 3.0 or later

If you don't meet these requirements, use Bluetooth unlocking instead, which works on all iPhones.

My key doesn't work sometimes - what should I try?

Try these troubleshooting steps in order:

1. For Bluetooth unlocking:

   • Make sure Bluetooth is enabled on your phone
   • Close and reopen the JustIN Mobile app
   • Position your phone closer to the lock

2. For NFC unlocking:

   • Ensure NFC is enabled in your device settings
   • Keep your phone screen unlocked (Android users check Screen unlocking setting)
   • Hold your phone directly against the lock reader

3. General troubleshooting:

   • Check for app updates in your app store
   • Restart your phone
   • Pull down to refresh your key list in the app

If problems persist, contact your key issuer.

Can I use JustIN Mobile without an internet connection?

Yes, once you've downloaded your keys, you can unlock doors without an internet connection. However:

• You need internet to initially receive keys and updates
• If your key expires while offline, you won't receive the renewal until you're back online

Why do I see "This number has no key assigned" even though I should have access?

This can happen when:

1. Wrong phone number: The number you entered doesn't match what your key issuer has on file
2. Timing issues: Your access hasn't started yet (check your check-in time)
3. Key not issued yet: Your key issuer hasn't created your key in their system
4. Booking problems: There may be an issue with your reservation or access request

What to do:

• Double-check your phone number
• Contact your key issuer (hotel, employer, building manager)
• Verify your booking or access dates

Can I share my digital key with someone else?

No, digital keys are tied to specific phone numbers and cannot be shared or transferred to other people. Each person who needs access must have their own key assigned by the key issuer.

If someone else needs access, they should contact the key issuer directly to request their own key.

How long do digital keys last?

Key duration depends on your key issuer:

• Hotels: Matches your stay dates
• Offices: Often match employment period or project duration
• Temporary access: May be for set hours or days

Keys automatically expire at the set time. You'll need to request a new key from your issuer if you need extended access.
