Analyze the question requirements

The question asks for a physical piece of evidence used to authenticate a user, which typically contains an embedded memory chip.

Evaluate the options

Using the Multi-factor Authentication and Identity Verification knowledge points:

• personal identification number (PIN): This is a knowledge-based factor (something you know), not a physical object.
• retina scanner: This is a biometric reader device used to scan physical characteristics, not a portable piece of evidence carried by a user.
• smart card: This is a physical plastic card (something you have) containing an embedded integrated circuit/memory chip used for secure user authentication.
• facial recognition software: This is a software application used to process biometric data, not a physical object.

The smart card perfectly matches the description of a physical piece of evidence containing an embedded memory chip.

Answer:

• personal identification number
