Touchless systems actually store the encrypted format of biometric data. They are not keeping the actual images as they are. This means that even if someone were to gain access to the data you have collected from these systems, they wouldn’t be able to retrieve any personal information from it.
The encryption process locks down sensitive data, practically making it impossible for anyone to breach it.
Another common misunderstanding is that using biometric systems shows that employers don’t trust their employees. Some people might think that keeping such close tabs on attendance means employers are doubting their workers.
