Check what your licence covers (devices, users, features), contact your supplier for a valid licence or upgrade, and avoid cracks, which risk malware and data loss.
Key takeaways
- Licences limit devices or features.
- Ask the supplier who sold the terminal.
- Avoid cracks.
- Keep the licence file safe.
01What licence limits exist
- Number of devices or terminals.
- Number of employees.
- Feature modules such as cloud or access control.
- Trial period.
02What to do
- Open About or Licence in the software and note the details.
- Contact the supplier who sold the terminal with the serial or order details.
- Ask whether you need an upgrade for more devices.
- Apply the licence they send.
03Why not a crack
Cracked copies can contain malware, break communication, stop updates and expose payroll data. The cost of one breach is far higher than a licence.
04Keep records
Store the licence file and invoice. If the PC dies, you will need them. See backup.
