Open the employee record and confirm the Area. See [departments and areas](https://qyvea.co.ke/zkbio-time-net-departments-and-areas). ## Check sync options 1. Open Device > Sync Data. 2. Tick Sync Employee Information (and fingerprints if needed). 3. Pick the right Area and device. 4. Click Sync Data. ## Read the log The progress window lists steps such as Connecting to Terminal, Get employees from device and Upload employees. A failure line tells you where it stopped. See [connection failed](https://qyvea.co.ke/zkbio-time-net-connect-to-terminal-failed). **Figure 1.** The sync log should show no failure lines. ## Overwrite setting The 'Overwrite previous information after download' option decides which side wins. Turn it on only if the device holds the correct, newer data. ## Check on the terminal On the K40 Pro open Menu > User Mgt and look for the new IDs. ## A typical scenario New hires were not appearing on a K40 Pro. They had been created without the area. Adding the area and syncing made them appear instantly. *Illustrative example based on common cases, not a named customer.* ## Common mistakes - Missing area. - Wrong sync options. - Wrong device selected. - Offline terminal. - Ignoring the log. ## Quick checklist 1. Check area 2. Check options 3. Check device 4. Sync 5. Read log 6. Check terminal list ## Frequently asked questions Does the employee need a fingerprint to upload? No, but they need one to punch by finger. Why does the count differ? Disabled or resigned employees may not upload. Can I upload one person only? Sync by selecting that person if your version allows. Are photos uploaded? Only on models that support photos. This guide is part of our [ZKTeco K40 and ZKBio Time.Net series](https://qyvea.co.ke/zkteco-k40-zkbio-time-net-guides-kenya).
