# Tracing systems in Emergency Exposure Management

A tracing system configured for a contact tracing data source enables you to identify
potentially exposed employees by running a diagnostic request.
The diagnostic request for an affected employee queries the contact tracing data to
identify people who might have interacted with the affected employee. You can select
multiple tracing systems in a diagnostic request to use multiple data sources to broaden the
coverage used to find potential exposure.

A tracing system can be a group of other tracing systems with a similar type of input data
source. For example, say you have Wi-Fi access data integration with multiple systems such
as Cisco DNA Spaces and Mist Systems. You could have a tracing system called Wi-Fi access
log and make it the parent tracing system of other tracing systems using the Wi-Fi input
data sources.

You can customize the tracing systems for data sources available in Emergency Exposure Management or set up a new tracing system. For more
information, see [Set up a tracing system for an exposure data source](https://www.servicenow.com/docs/5VdFtY0ftrachneXPzqzZw "Set up a tracing system for your exposure data source to identify potentially exposed employees by running the diagnostic requests for an affected employee.").

For some tracing systems to be available in Emergency Exposure Management,
you must install other Safe Workplace suite and Emergency Response Operations applications.

## Tracing systems installed with Emergency Exposure Management {#tracing-systems-exposure-mgnt__section_qsg_lt2_bnb}

These tracing systems are active by default.{#tracing-systems-exposure-mgnt__table_sgm_ndx_cmb__entry__2}

| Tracing system | Query |
|-|-|
| Location | Employees co-located with the affected employee, for example, on the same floor or building. |
| Outlook meetings Microsoft Office 365 | Employees who accepted the same meetings as the affected employee during the specified time period. |
[Table 1. Emergency Exposure Management tracing systems]

{#tracing-systems-exposure-mgnt__table_sgm_ndx_cmb}

## Tracing system installed with Workplace Core {#tracing-systems-exposure-mgnt__section_cfc_b52_bnb}

This tracing system is not active by default. To use this tracing system for identifying
potentially exposed employees, activate it and also configure the corresponding data source
in Workplace Core.  
For more information, see [Install Workplace Safety
Management](https://www.servicenow.com/docs/pEid~a95k2oNzcmsw65ddg "You can install the Workplace Core application if you have the admin role. This application includes optional demo data.").{#tracing-systems-exposure-mgnt__table_sgm_nyx_chb__entry__2}

| Tracing system | Query |
|-|-|
| Workplace reservations | Employees who had reservations for the same shifts as the affected employee during the specified time period. |
[Table 2. Workplace Core tracing system]

{#tracing-systems-exposure-mgnt__table_sgm_nyx_chb}

## Tracing systems installed with Contact Tracing {#tracing-systems-exposure-mgnt__section_p3t_nt2_bnb}

These tracing systems are not active by default. To use these tracing systems for
identifying potentially exposed employees, activate them and also configure the
corresponding data sources in Contact Tracing.  
For more information, see [Setting up Contact Tracing](https://www.servicenow.com/docs/Eq8NiOD_R~mhLpZc7kEZlQ "Configure system properties, scheduled jobs, script includes, Wi-Fi access log integration, and outreach notifications to aggregate contact tracing information for various data sources.").{#tracing-systems-exposure-mgnt__table_q3t_nt2_bnb__entry__2}

| Tracing system | Query |
|-|-|
| Badge reader | Queries the Badge Access Register \[sn_imt_tracing_badge_access_register\] table to fetch employees who swiped their badge on the same badge reader devices as the affected employee during the specified time period. |
| Employee daily log | Queries the Daily Contact Logs \[sn_imt_tracing_daily_contact_log\] table to fetch employees with whom the affected employee interacted during the specified time period. |
| Visitor log | Queries the Visitor Request For Entry \[sn_imt_monitoring_visitor_request_for_entry\] table to fetch visitors who interacted with the affected employee during the specified time period. Visitors who visited the workplace on invitation from the affected employee and have been screened through and let in are queried. Ensure that you have installed Employee Health Screening to use this tracing system. |
| Wi-Fi access log | Queries the Wi-Fi Access Register \[sn_imt_tracing_wifi_access_register\] table to fetch employees who used the same Wi-Fi access points as the affected employee during the specified dates. Wi-Fi access log data used to identify potentially impacted employees depends on Wi-Fi location preferences and available integrations. The tracing system has the following child tracing systems based on the data source: * Mist Systems * Cisco DNA Spaces {#tracing-systems-exposure-mgnt__ul_z2x_hdl_cnb} For more information, see [Retrieving Wi-Fi access log data](https://www.servicenow.com/docs/gEIu57XJ0hTfRdkJ1KaFvw). Note: The period for which you can get the data via a real-time API depends on the data retention policy of your Wi-Fi service provider. |
| Handheld/Wearables | Queries the Wearable Access Register \[sn_imt_tracing_wearable_access_register\] table to fetch employees equipped with handheld or wearable devices who were in the close proximity with the affected employee during the specified time period. The Handheld/Wearables tracing system has the Zebra MotionWorks Proximity tracing system added as a child tracing system. |
| Kinexon SafeZone | Uses an integration with the KINEXON SafeZone API to identify potentially exposed users with KINEXON wearable devices who were in close proximity with the affected KINEXON user during the specified dates. For more information, see [Configure KINEXON integration](https://www.servicenow.com/docs/8ttxybmIqe8A6BGcBU_BIQ "Configure Contact Tracing and enable the KINEXON SafeZone tracing system to use data from KINEXON wearable devices in diagnostic requests. This data enables the identification of potentially exposed contacts based on the interactions and proximity of users with KINEXON wearable devices."). |

## Tracing system installed with Field Service Management {#tracing-systems-exposure-mgnt__section_knw_nt2_bnb}

This tracing system is not active by default. To use this tracing system for identifying
potentially exposed employees, activate it and also configure the corresponding data source
in Field Service Management.  
For more information, see [Emergency Exposure Management for
field service agents](https://www.servicenow.com/docs/access?context=monitoring-analytics-fsm&version=xanadu&pubname=xanadu-field-service-management&section=exposure-management-for-agents&ft:locale=en-US).{#tracing-systems-exposure-mgnt__table_lnw_nt2_bnb__entry__2}

| Tracing system | Query |
|-|-|
| Field service | Customers attended by an affected field agent during the specified time period. Also queries other field agents who interacted with the affected agent or visited the same customer as the affected agent during the specified time period. |
