When Apple introduced the iPhone X, it marked a significant shift in biometric security by replacing the Touch ID fingerprint reader with Face ID, a 3D facial recognition system. While this innovation was groundbreaking, it also raised questions about practicality. As an example,during the pandemic,when masks became ubiquitous,Face ID struggled to function effectively,forcing Apple to tweak the system to scan only the area around the eyes. Now, with the launch of the Vision Pro glasses, another limitation has surfaced: Face ID doesn’t work when the glasses are worn.
Face ID remains the primary biometric security method for iPhones. But why hasn’t apple considered reintroducing Touch ID as an alternative? A fingerprint reader could be embedded in the side button or under the display, a feature already common in Android devices.
While the Vision pro glasses are not yet mainstream, their user base is expected to grow, especially as Apple plans to release more affordable models in the future. However, the company’s oversight regarding Face ID compatibility with the glasses is puzzling. Apple could possibly adjust Face ID to scan only the visible areas of the face, but this would be far more complex than the mask-related adjustments. Alternatively, a hybrid mode could be introduced, allowing users to unlock their iPhones by simply looking at them while wearing unlocked Vision Pro glasses—provided both devices are linked to the same Apple ID.
Is It Time for Touch ID to Make a Comeback?
Perhaps it’s time for Apple to reconsider its approach and reintroduce Touch ID to iPhones. There’s no technical barrier preventing this; integrating a fingerprint reader into the power button would be straightforward, as Apple has already done with iPads.Additionally, under-display fingerprint sensors, available in both optical and ultrasonic forms, have been widely adopted by Android manufacturers like Samsung, Xiaomi, and Google. These proven technologies could easily be incorporated into iPhones.
Touch ID would offer a more natural and versatile authentication method in many scenarios. Such as, contactless payments or swift access to apps could be more seamless with a fingerprint scan than with facial recognition. Each method—Face ID and Touch ID—has its strengths and weaknesses, and offering both would empower users to choose the option that best suits their needs.
By deploying both biometric technologies, Apple could address the limitations of Face ID while maintaining its commitment to innovation. The only minor adjustment required would be ensuring that phone cases accommodate the power button, leaving it accessible for fingerprint scanning.
Would you welcome the return of Touch ID to iPhones? If so, would you prefer an under-display fingerprint sensor or one integrated into the power button, like on iPads?

how did Apple’s approach to Face ID updates during the pandemic compare to other biometric systems, such as fingerprint or iris recognition?
Interview with Dr. Emily Carter, Biometric Security Expert, on the Evolution of Face ID and Biometrics in a Masked World
Archyde News Editor: Good afternoon, Dr. Carter. Thank you for joining us today. As a leading expert in biometric security, you’ve been at the forefront of analyzing how technologies like Apple’s Face ID have evolved, especially during the pandemic. Let’s start with the introduction of Face ID in the iPhone X. What made this technology so groundbreaking at the time?
dr. Emily Carter: Thank you for having me. The introduction of Face ID in 2017 was a significant leap forward in biometric security. Unlike traditional facial recognition systems,Face ID utilized a 3D depth-sensing system powered by infrared cameras and dot projectors. This allowed it to create a highly accurate map of the user’s face, making it far more secure than 2D systems. It was also designed to adapt to changes in appearance, such as growing a beard or wearing glasses. Though, its reliance on full facial recognition posed challenges in real-world scenarios, particularly during the pandemic.
Archyde News editor: Speaking of the pandemic, masks became a necessity, and Face ID struggled to function effectively. How did this impact the perception of biometric security?
Dr. Carter: The pandemic exposed a critical limitation of Face ID: its inability to recognize users when a significant portion of their face was obscured. This lead to frustration among users who had to repeatedly enter passcodes, undermining the convenience that biometric systems are designed to provide. It also highlighted the importance of designing systems that can adapt to real-world conditions. Apple responded by introducing updates that allowed Face ID to recognize users with masks, but this required users to enable option authentication methods, such as Apple Watch verification.
Archyde News Editor: That’s captivating. How did Apple’s approach compare to other biometric systems during the pandemic?
Dr. Carter: Other biometric systems, such as fingerprint and iris recognition, were less affected by masks. For example, fingerprint scanners on Android devices continued to function seamlessly. However, these systems have their own limitations. Fingerprint recognition can struggle with wet or dirty fingers, and iris recognition requires precise alignment. The pandemic underscored the need for multimodal biometric systems that combine multiple traits—like face, fingerprints, and iris—to ensure reliability across diverse scenarios.
Archyde News Editor: You mentioned multimodal biometric systems. Do you see this as the future of biometric security?
Dr. Carter: Absolutely. Multimodal systems offer a more robust and flexible approach to authentication. By combining multiple biometric traits, they can compensate for the weaknesses of individual methods.as an example, if a user’s face is partially obscured, the system could fall back on fingerprint or iris recognition. This approach aligns with recommendations from organizations like ICAO and IATA, which advocate for the use of multiple biometric traits in identity verification systems.
Archyde News Editor: Looking ahead, what innovations do you anticipate in the field of biometric security?
Dr. Carter: We’re already seeing advancements in areas like periocular recognition, which focuses on the region around the eyes. This technology proved useful during the pandemic when masks covered the lower face. Additionally, AI-driven systems are becoming more adept at handling partial obstructions and variations in appearance. I also expect to see greater integration of biometric systems with wearable devices, offering users more seamless and secure authentication options.
Archyde News Editor: Thank you, Dr. Carter, for sharing your insights.It’s clear that the field of biometric security is evolving rapidly, and the lessons learned during the pandemic will undoubtedly shape its future.
Dr. carter: Thank you. It’s an exciting time for biometrics, and I look forward to seeing how these technologies continue to improve and adapt to our changing world.
This interview highlights the challenges and innovations in biometric security, particularly in the context of Apple’s Face ID and the pandemic. Dr. Carter’s expertise provides valuable insights into the future of this rapidly evolving field.
