Final answer:
Physical appearance, hair color, facial hair, and other factors can change over time, making them unreliable indicators of an ID's authenticity.
Step-by-step explanation:
The features on an ID that are most likely to have changed since it was issued, making them potentially unreliable indicators of the id’s authenticity when comparing the photo to the guest, include:
Physical appearance: People's appearances can change over time due to factors such as aging, weight gain or loss, hairstyle changes, etc. This can make it difficult to accurately match the photo on the ID to the guest.
- Hair color: Hair color can be easily changed with dyes or hair treatments, making it an unreliable indicator of identity.
- Facial hair: If the photo on the ID shows the person with facial hair, but they are currently clean-shaven or vice versa, it can create confusion and uncertainty.
- Other factors: Other factors that can contribute to changes in appearance and potentially affect identification include changes in fashion choices, makeup, and accessories.
