Apple Patents Screen Fingerprint Tech? Facts
Yes, Apple has been granted multiple patents for under-display fingerprint technology, but as of early 2025, no iPhone model includes it. The patents cover optical and ultrasonic methods for reading fingerprints through a screen, yet Apple continues to rely on Face ID for biometric authentication on its flagship devices.
Background: Why the Patent News Matters
Patents are legal protections for inventions, not commitments to ship a product. Apple files hundreds of patents each year, and many never appear in a commercial device. The recent screen fingerprint patents are notable because they show Apple is actively exploring the technology, even if it has not announced a release date. Industry analysts have speculated about Touch ID returning to the iPhone since 2020, when the COVID-19 pandemic made face recognition impractical with masks. However, Apple has not confirmed any plans, and the patents themselves do not guarantee a future product.
How Under-Display Fingerprint Sensors Work
Two main technologies exist for reading fingerprints through a screen:
- Optical sensors use a bright light to illuminate your finger and a camera-like sensor to capture the fingerprint image. They are common in mid-range Android phones.
- Ultrasonic sensors use high-frequency sound waves to map the ridges and valleys of your fingerprint in 3D. They work better with wet or oily fingers and are more secure.
Apple’s patents describe both types, with specific designs for integrating the sensor into the OLED display stack. The sensor would sit under the screen and capture your fingerprint when you press on the glass. This is different from the older Touch ID home button, which was a physical button with a capacitive sensor.
Apple’s Patent History: What’s Actually in the Filings
Apple has filed several patents related to under-display fingerprint sensing. For example, a 2023 patent application described a system using shortwave infrared light to read fingerprints through the screen, which could work even with a bright display. Another patent from 2021 detailed an ultrasonic sensor embedded in the display. These filings show Apple is researching ways to make the technology more accurate and secure than current Android implementations. However, patents are often filed for defensive purposes or to protect future options, so their existence alone is not proof of a shipping product.
Why Apple Might Prefer Face ID
Apple has invested heavily in Face ID, which uses a TrueDepth camera to map your face in 3D. It is generally more secure than fingerprint sensors, with a false match rate of about 1 in 1,000,000 compared to 1 in 50,000 for Touch ID. Face ID also works without any physical contact, making it convenient when your hands are wet or gloved. Apple has repeatedly stated that Face ID is more secure and user-friendly, and it has integrated the technology into the iPhone, iPad, and even the Mac. Switching back to fingerprint would require significant hardware changes and might confuse users who are accustomed to Face ID.
Common Misconceptions About Apple’s Patents
One common misconception is that a patent means Apple is about to release a phone with the technology. In reality, patents are filed years in advance, and many are never used. Another misconception is that Apple has never patented fingerprint technology; in fact, the company has held patents for capacitive fingerprint sensors since the early 2000s, long before Touch ID existed. Also, some people believe that under-display fingerprint sensors are inherently less secure, but that depends on the implementation. Apple’s patents describe advanced features like liveness detection and anti-spoofing, which could make its version more secure than current Android sensors.
Potential Benefits of Under-Screen Fingerprint on iPhone
If Apple were to release an iPhone with under-screen fingerprint, it would offer several advantages:
- Works with masks, gloves, and in low light.
- Allows biometric authentication when the phone is lying flat on a table.
- Could enable multiple fingerprints for different users or actions.
- May be faster than Face ID in some situations.
However, Apple would need to ensure the sensor works reliably with screen protectors and does not increase the cost or thickness of the device. The company might also combine fingerprint with Face ID for a dual-biometric approach, similar to some Android phones.
How to Check If Your iPhone Has Under-Display Fingerprint
As of now, no iPhone has under-display fingerprint. If you want to check a specific model, go to Settings > Face ID & Passcode (or Touch ID & Passcode on older models). If you see “Touch ID & Passcode,� your iPhone has a fingerprint sensor, but it is in the home button (iPhone 8 and earlier) or the side button (iPad Air and iPad mini). If you see “Face ID & Passcode,� your iPhone uses facial recognition. No iPhone has both. To verify whether a future model includes under-display fingerprint, wait for Apple’s official announcement; unofficial rumors are not reliable.
Alternatives to Under-Display Fingerprint
If you want fingerprint unlock on an iPhone today, you have limited options. The iPhone SE (2nd and 3rd generation) has Touch ID in the home button. You can also use an Apple Watch to unlock your iPhone when wearing a mask, but that is not a fingerprint sensor. For Android users, under-display fingerprint is common, but the security varies by manufacturer. Some users prefer a separate fingerprint sensor on the back or side, which is often faster and more reliable than under-display versions. Ultimately, the choice depends on your priorities: convenience, security, or cost.
Frequently Asked Questions
Will the iPhone 16 have under-display fingerprint?
As of early 2025, there is no official confirmation. Rumors have suggested Apple might introduce under-display fingerprint in future models, but the company has not announced any such plan. Apple typically keeps its product roadmap secret, so any prediction is speculative.
Is under-display fingerprint less secure than Face ID?
In general, yes. Face ID has a lower false match rate than most fingerprint sensors. However, Apple’s patents describe advanced security features that could narrow the gap. The actual security depends on the specific implementation, not the technology itself.
Can I add a fingerprint sensor to my iPhone?
No, you cannot add a fingerprint sensor to an iPhone that does not have one. The hardware is not present, and there is no way to retrofit it. You can use a Bluetooth fingerprint reader for some apps, but it will not unlock the phone.
Why did Apple remove Touch ID?
Apple replaced Touch ID with Face ID starting with the iPhone X in 2017. The company cited improved security and a more seamless user experience. Face ID also allowed for a nearly bezel-less display, as it eliminated the need for a home button.
Does Apple’s patent mean the technology will definitely appear?
No. Many patents are never commercialized. Apple files patents to protect its intellectual property and explore options. A patent is not a product roadmap.
