Should Employee ID Cards Include Date of Birth or Emergency Contact Info? Seeking Advice

Dear Seniors, we are in the process of revising our ID cards for all employees. The current ID card includes Employee Name, Employee Code, Department, Blood Group, and Date of Birth. In my opinion, Date of Birth is an employee's personal information that should not be displayed on the ID card. Instead of Date of Birth, I suggested to management to include the employee's emergency contact number (a number of any immediate family member).

Please help me understand the purpose of including Date of Birth on the ID card and whether including an emergency number is the right step.

Only information that is relevant and accessible to establish the identity of the employee is good enough to be mentioned on the ID card. The date of birth is not needed to be included. In fact, many employees may not want to share this information in the public domain.
