Read full descriptionHide full description
Activate and manage your E Sentry System assets. Users with an NFC compatible device can inspect asset tags to view and submit information, updating its history with the cloud. Activated users can view their assigned routes and designate their current route as needed, showing them which assets require an inspection and cataloging their progress through the route. All check-in information is synched with the cloud service allowing admins to review completed and assigned routes, create new routes, and review inspection history on each asset tag. Historical information is converted into trends and can be exported into an excel compatible document for review and maintenance.
