Which of the following is NOT part of the identification process using PDA?

The identification process using PDA (Personal Digital Assistant) typically involves methods to verify the identity of a donor to ensure safety and compliance with regulations. This includes using biometric data, such as a finger scan, which provides a unique identifier linked to the individual, and photo identification, which visually matches the individual to the ID they present. Additionally, the last four digits of the Social Security Number (SSN) can help verify the identity against existing records.

On the other hand, the donor’s occupation is not a standard requirement for the identification process during plasma donation, as it does not serve to directly confirm the identity of the donor in the same way that the other methods do. While knowing a donor's occupation may provide additional context or information, it is not a critical piece of data needed to fulfill the identification requirements during the donation process. Therefore, choice related to the donor’s occupation stands out as not being integral to the identification process using a PDA.
