Which of the following information is NOT typically found on a Professional Identification Card?

The correct choice identifies information that is not generally included on a Professional Identification Card. A Professional Identification Card typically serves to authenticate the credentials of individuals in various fields, including healthcare and laboratory services.

The registration number is essential as it uniquely identifies the professional within the regulatory framework. Dates of issuance and expiry provide necessary information regarding the card's validity, ensuring that the holder is practicing within the timeframe of their certification. The complete name of the professional is also crucial for identification purposes, allowing for clear recognition of the individual’s qualifications.

In contrast, the signature of the Professional Regulatory Board (PRB) Chairman is not a standard feature of these cards. While it may serve as a form of validation for some official documents or certificates, it is less relevant for an identification card, where the primary purpose lies in presenting personal and credential-related information rather than endorsing it with a signature. This is why the information regarding the PRB Chairman's signature is considered the exception among the listed choices.
