4. Can a prospective employer record my ID card number or collect a copy of my ID card when I attend a job interview?
In order to check whether you have applied for or held a position in the company before, the prospective employer can collect your ID card number. However, a copy of your ID card should not be collected unless and until you become an employee of that company.
