How it works?
Our readerless mobile credentials use the users mobile as the active NFC reader to unlock a door. Users can unlock using smartphone NFC technology, a smart watch complication, and iPhone or Android Widgets.
Touch, tap, unlock
- The user taps their smartphone onto the wireless Smart Access Tile next to the door or uses the iPhone or Android widget to unlock the door remotely.
- A user authentication check is carried out.
- Access is granted displayed by a green tick on
the phone screen.
Intelligent and secure cloud infrastructure
- The user’s smartphone connects to Sentry
Interactive’s cloud service. - Sentry Interactive’s cloud service
communicates via SSL/SSH to the building’s
door access controller. - The Sentry Interactive cloud is secured through
AWS.
Seamless cloud connection
- The building’s access controller acknowledges
the access request from the Sentry Interactive
cloud. - A signal is sent to release the electric/magnetic
door lock and unlock the door.
Secure, logged door entry
- The door unlocks in under a second and the user enters the building
- A log-file stores unlock data including date,
time and the door that was unlocked.

Frequently asked questions
When a user taps their smartphone against the Smart Access Tile next to a door, the phone acts as an active NFC reader. It authenticates the user and connects to Sentry Interactive’s cloud service, which communicates with the building’s door access controller via SSL/SSH. The controller then makes the final decision and sends a signal to release the door lock, all in under a second.
