Avoid queues and check in before you arrive

Sine Pro is free and available for iPhone and Android. It allows visitors, contractors, staff, students, couriers and any other groups to check in to your site when they are nearby.
We use geofencing to set up a virtual perimeter around your facility that enables repeat visitors to check in and out of your site with ease.
When you leave a site, users will be sent a notification reminding them to check out too. The app can also be used by hosts at a site to alert them that their visitor has arrived.

Saves time and helps you go paperless

Just tap the site name displayed on the list of nearby sites to your location. Get alerts when to arrive and depart from site to remind you to check in and check out.
Sine also works to verify attendance with QR codes displayed on site posters, removing the need for an iPad at site. Just scan the QR code when you arrive and depart.


Get verified and access more sites

Add your photo ID, verify your mobile number and email and get access to more sites that require verification.
Sine’s unique verification process brings an extra layer of security to visitor & contractor management processes. Know who’s on site for sure.

Know who’s on site

Receive notifications via email, SMS or to Sine Pro when your visitor arrives.
Choose to accept or reject visitors or contractors which is ideal if you operate a remote site. It’s also perfect for approving permits and checking who’s really on site.
