# Requesting access

### Requesting access at a door

A user can request access by presenting their smartphone or an SMB key tag at the door’s reader. The smartphone must host the Gallagher SMB app with a valid mobile credential for the site.

iOS smartphones communicate with the reader using Bluetooth®. Android smartphones communicate with the reader using NFC or Bluetooth®. A tag will communicate with the reader using NFC.

Access granted events will appear in the History log of the Site Manager’s app when access has been granted and taken through the door. The user’s name and door name are reported.

{% hint style="info" %}

* Ensure Bluetooth® is enabled on your device. Android devices also need NFC enabled.
* Location permission must be enabled on Android devices, as without this permission the device’s Bluetooth® won’t scan, even if Bluetooth® itself is enabled.
* The area assigned to the door must be disarmed before the door will unlock. Two factor authentication is required to disarm.
* Users are given privilege to enter areas not doors, which means a user given access to a particular area will be able to enter through any of the access-controlled doors leading into that area.
* Only Site Managers and privileged Site Admins can view doors and their locked/unlocked status within the Gallagher SMB app.
* Doors will lock automatically when the area they are associated with is armed.

**To request access:**

1. Open the Gallagher SMB app (the app can be running in the background).
2. Place your smartphone on or near the reader.
3. If successful, the reader’s LED will turn green and the door will temporarily unlock.

If you receive an access denied message, you will either have the wrong permission for the door or the area will be armed. Contact your Site Manager for assistance.
