Aadhaar is a unique identification number issued by the Indian government to its citizens. It consists of a 12-digit number that serves as a proof of identity and address. In an employee master, Aadhaar details refer to an employee’s Aadhaar number and other relevant information related to their Aadhaar card.

In India, employers may require employees to provide their Aadhaar details for various purposes such as payroll processing and tax compliance. When collecting Aadhar details, it is important for employers to comply with applicable laws and regulations governing data privacy, including obtaining necessary consents from employees before collecting or using their personal data.

It is also advisable for employers to take necessary measures to protect the confidentiality of employee data, including storing it securely and limiting access only to authorized personnel who need such information.
