TNCID is a shared persistent identifier that improves user recognition compared to both third-party and first-party cookies. This enhanced identification capability enables publishers and advertisers to consistently recognize their audiences, leading to improved monetization and more precise targeting.  The Newco User ID sub-module adds powerful TNCID user identification technology to your Prebid.js bidstream. 
For more details, visit our <a href="https://www.thenewco.tech">website</a> and contact us to request your publisher-id and the on-page tag.

## Prebid Configuration

First, make sure to add the TNCID submodule to your Prebid.js package with: 

```bash
gulp build --modules=tncIdSystem,userId
```

You can configure this submodule in your `userSync.userIds[]` configuration:

pbjs.setConfig({
    userSync: {
        userIds: [{
            name: 'tncId',
            params: {
              url: 'TNC-fallback-script-url' // Fallback url, not required if onpage tag is present (ask TNC for it)
            },
            storage: {
              type: "cookie",
              name: "tncid",
              expires: 365 // in days
            }
        }],
