Apple’s new iPhone X does away with the Home button, which has been a fixture since the original iPhone and has long served as the Touch ID sensor. To replace Touch ID, Apple developed a new facial recognition technology called Face ID. With Face ID, the iPhone X scans your face to authenticate you instead of using your fingerprint. It is truly amazing technology, but we’ve been getting questions that we’d like to answer here. If you have others, get in touch!
How does Face ID work?
Magic. Well, close. As science fiction author Arthur C. Clarke said, “Any sufficiently advanced technology is indistinguishable from magic.” Face ID is cutting-edge technology that uses Apple’s TrueDepth camera system to project over 30,000 invisible dots onto your face. Then it illuminates your face with infrared light and takes an infrared image. Finally, it translates that image into facial recognition data that’s encrypted and stored within the iPhone’s Secure Enclave (the data never leaves your iPhone).
Face ID updates its mathematical representation of your face over time to keep up with how your appearance changes.
How secure is Face ID?
Extremely. Apple claims that Touch ID’s false positive rate—the number of people who would have to try logging in to your iPhone before someone would succeed randomly—is 1 in 50,000. In contrast, Apple says that Face ID’s false positive rate is 1 in 1,000,000. It can’t be fooled by a picture or a simple mask, although a high-enough quality 3D reproduction of your face might get past it, just as a sufficiently good cast of your fingerprint could fool Touch ID.
However, Face ID has trouble distinguishing between identical twins and siblings who have nearly identical features. So if you have an evil twin, stick to a Touch ID-based iPhone or your passcode! The probability of an incorrect match is also higher with children under 13, since their facial features haven’t become sufficiently distinct yet.
By default, Face ID works only when you look at the iPhone X—it can’t be unlocked by your face when you’re sleeping.
How fast is Face ID?
Not quite as fast as Touch ID in current iPhones, but fast enough that you likely won’t notice. When you pick up your iPhone X so you can look at it, Face ID will, in most cases, have already recognized you.
This quick recognition is possible in part because the iPhone X can start scanning early, thanks to iOS’s Raise to Wake feature and a new Tap to Wake feature that automatically wakes the iPhone X when you touch the screen.
What if Face ID doesn’t work?
First off, things like wearing a hat, scarf, or glasses won’t confuse Face ID, nor will growing or shaving a beard. Thanks to that infrared camera, it even works in complete darkness. However, Face ID does fail occasionally. One reason for a Face ID failure is holding the iPhone X too close to your face—this is easy to do accidently if you’re nearsighted and not wearing your glasses. (Some sunglasses prevent Face ID from seeing your eyes, but you can work around that problem by disabling Require Attention for Face ID in Settings > Face ID & Passcode.)
To make Face ID retry a facial scan, hold the iPhone X at a normal viewing distance, tilt it away from you, and then tilt it back to your normal viewing position. If that doesn’t work, or if you want to let someone else use your iPhone, enter the passcode. Entering the passcode is always an option.
Alas, unlike Touch ID, which let you enroll up to five fingers (so family members could unlock your iPhone without using the passcode), Face ID lets you have only a single face.
Can I use Face ID for anything besides unlocking?
Yes, Face ID completely replaces Touch ID, so you can use it to authenticate when you’re using Apple Pay, or the App Store or iTunes Store. Plus, apps that previously relied on Touch ID, such as the 1Password or LastPass password managers, will automatically use Face ID instead.
We hope Apple can make the hardware necessary for Face ID cheaply enough to bring it to other devices as well. Wouldn’t it be nice if you could walk up to your Mac and have it automatically unlock because it had recognized your face?

At its highly anticipated product announcement event at the new Steve Jobs Theater, Apple didn’t disappoint.
The big news was the revolutionary iPhone X, which eliminates the Home button and unlocks by recognizing your face. Apple also announced the evolutionary iPhone 8 and iPhone 8 Plus; a cellular-capable Apple Watch Series 3; and the Apple TV 4K, which supports 4K HDR video. The company said that iOS 11 and watchOS 4 would ship on September 19th, and later noted that macOS 10.13 High Sierra would arrive September 25th.
iPhone 8 and iPhone 8 Plus Add Wireless Charging
Rather than calling the new model the iPhone 7s, Apple jumped to the iPhone 8 name to acknowledge significant hardware changes, notably a mostly glass case designed to allow wireless charging. Otherwise, the iPhone 8 and iPhone 8 Plus largely follow in the footsteps of the iPhone 7 and 7 Plus, featuring the same 4.7-inch and 5.5-inch screens, respectively. They’re almost the same size as the previous models, varying only by fractions of a millimeter in different dimensions, and are water and dust resistant too.
Although the iPhone 8 models still sport a Lightning port (and come with a headphone jack adapter), you’ll charge them by setting them on a charging pad based on the Qi wireless charging standard (Qi is pronounced “chee”). Furniture retailer IKEA has even built such chargers into some of its tables. In 2018, Apple plans to release an AirPower charging mat that will charge an iPhone 8 or iPhone X, Apple Watch Series 3, and AirPods with a new charging case—all with no cables.
The iPhone 8 and 8 Plus screens now support Apple’s True Tone technology, which changes brightness and color based on the ambient light. Plus, their stereo speakers are 25% louder than in the iPhone 7 and have deeper bass.
Under the hood, the iPhone 8 models include a new A11 Bionic chip that Apple claims is the most powerful chip ever in a smartphone. The chip’s performance will particularly benefit games; apps that rely on machine learning; and apps using augmented reality, which can seamlessly place virtual objects in live video of the real world.
Although the basic rear-facing camera in the iPhone 8 is still 12 megapixels, it uses an all-new sensor that captures 83% more light and provides deeper pixels, a new color filter, and optical image stabilization, all while using less power. That adds up to pictures with better color saturation, a wider dynamic range, and lower noise.
Like the iPhone 7 Plus, the iPhone 8 Plus sports dual 12-megapixel rear-facing cameras, one with an ƒ/1.8 aperture and the other at ƒ/2.8. Those cameras have the same new sensor, and iPhone 8 Plus owners will be able to try a beta of Apple’s new Portrait Lighting feature, which lets you apply studio-quality lighting to your scene as you compose the shot. You can even change the lighting afterward.
Both iPhone models boast improved video capture as well, in part due to a new image signal processor that provides faster autofocus in low light conditions. You can now shoot 4K video at 24, 30, or 60 frames per second, up from just 24 fps in the iPhone 7. And, you can capture slo-mo video in 1080p resolution at 120 or 240 fps, whereas the iPhone 7 was limited to 120 fps.
The iPhone 8 costs $699 for a 64 GB model and $849 for a 256 GB model. Available colors are gold, silver, and space gray. Add $100 to either price for the iPhone 8 Plus. Apple will begin taking pre-orders on September 15th, with general availability a week later.
If those prices are a bit steep for you, Apple continues to sell the iPhone 7 and 7 Plus, the iPhone 6s and 6s Plus, and the iPhone SE starting at $349.
iPhone X Introduces Face ID and Super Retina Display
The iPhone 8 may be a small step up from the iPhone 7, but the new iPhone X is a giant leap into the future, setting the standard for the smartphone of tomorrow. Pronounced “iPhone Ten,” Apple’s new flagship iPhone boasts a stunning, edge-to-edge screen that fills almost the entire front face and eliminates the Home button. It shares the iPhone 8’s glass back and support for wireless charging.
Although the iPhone X’s 5.8-inch screen is physically larger than the iPhone 8 Plus’s 5.5-inch screen, losing the bezel means that the iPhone X is just a few millimeters larger than the iPhone 8 and just a bit heavier. The extra size must have given Apple more room for the battery, since the iPhone X is supposed to last 2 hours longer than the iPhone 7 or 8.
You’ll see more on the iPhone X’s OLED display, which Apple dubbed “Super Retina,” since it has more pixels—2436-by-1125 at 458 pixels per inch—than any previous iPhone. In comparison, the iPhone 8 Plus is only 1920-by-1080 at 401 ppi.
With no Home button, you’ll interact with the iPhone X in different ways. You can wake an iPhone X with the Raise to Wake setting or by tapping on its screen. You invoke Siri with “Hey, Siri” or by pressing the new side button. To unlock the iPhone X, you swipe up from the bottom of the screen while looking at the iPhone X, and it uses Apple’s new Face ID technology to recognize your face, much like Touch ID did with your fingerprint in the past. Swiping up from the bottom of the iPhone X screen works across the system for jumping back to the Home screen or (if you pause briefly) opening the app switcher.
Face ID seems like magic, but it relies on the TrueDepth front-facing camera system—that notch on the top of the screen—which includes a 7-megapixel camera, infrared camera, flood illuminator, dot projector, and more. Face ID can recognize your face even in the dark, and it continually adapts to your changing look, so it can handle glasses, hats, beards, and more, all without being fooled by a photo of your face.
Like the iPhone 8 Plus, the iPhone X sports a pair of rear-facing cameras, but with slightly different specs. One has an ƒ/1.8 aperture, but the other is ƒ/2.4, as opposed to f/2.8 on the iPhone 8 Plus, and lets in 36 percent more light. The iPhone X also offers dual optical stabilization (on both lenses) for better low-light photos and videos.
All this technology doesn’t come cheap—a 64 GB model costs $999, and a 256 GB model is $1149. You can choose between silver and space gray. Regardless, you’ll have to wait a bit longer for the iPhone X because Apple plans to start taking orders on October 27th, with general availability on November 3rd.
Apple Watch Series 3 Adds Cellular
The original Apple Watch couldn’t do much more than tell time when separated from its companion iPhone. The Apple Watch Series 2 gained a GPS to track your location on its own when you were running or biking. But now the Apple Watch Series 3 includes a cellular chip that allows it to make phone calls, get messages, use Siri, stream tunes from Apple Music to AirPods, and more all while your iPhone sits safely at home. It uses the same phone number but will cost an extra $10 per month from your carrier.
To make untethered communication possible, Apple built the cellular antenna into the display and developed a special electronic SIM that’s about one-hundredth the size of an iPhone’s nano SIM. The Series 3 also boasts a faster processor that speeds up app performance and allows Siri to talk back you, along with a barometric altimeter to measure relative elevation.
Amazingly, the Series 3 case is the same size as the Series 2, although the back crystal is a hair thicker. Battery life in mixed use remains at up to 18 hours, though you’ll get only an hour of battery life when making phone calls.
The Apple Watch Series 3 has an aluminum body in three finishes: gold, silver, and space gray. For a different look (and potentially a lot more money), you can get Nike+ aluminum models, Hermès stainless steel models, and Apple Watch Edition ceramic models. Apple is also now offering a new Sport Loop band that’s meant to be light, stretchable, and breathable.
You can pick from two Series 3 models: one with just a GPS chip like the Series 2 for $329 and one with both GPS and cellular capabilities for $399. Pre-orders start September 15th, with general availability on September 22nd. Apple no longer sells the Series 2 but has dropped the price of a Series 1 to $249.
Apple TV Adds Support for 4K Video
Apple’s set-top box hasn’t seen many changes of late, which makes the new Apple TV 4K all the more welcome for video buffs. The new device now supports two key video technologies: 4K and HDR. 4K video provides about four times as many pixels as are in 1080p video, and HDR (High Dynamic Range) supports more colors. The result is video that looks fabulous, with more detail, deeper colors, and better contrast than ever before.
To see all that goodness, you’ll need a 4K TV that supports either the Dolby Vision or HDR10 standard—in other words, unless you’ve bought a TV in the last year or two, you’ll probably need a new one. Check the specs carefully!
The third part of the puzzle, after you have a 4K TV and an Apple TV 4K, is 4K HDR content. Apple is working with major movie studios to bring 4K HDR video content to iTunes at the same price as HD movies. You’ll even get an automatic upgrade to 4K HDR versions of iTunes HD movies you’ve purchased, when they become available. Netflix 4K HDR streaming is expected immediately, and Amazon Prime Video should offer 4K HDR video on the Apple TV later this year.
Dealing with all the 4K HDR video requires beefier hardware. The A10 Fusion chip doubles overall performance and quadruples the graphics processing speed over the fourth-generation Apple TV. The Apple TV 4K also sports faster and more modern networking connections: Gigabit Ethernet, simultaneous dual-band 802.11ac Wi-Fi, and Bluetooth 5.0.
A 32 GB model of the Apple TV 4K costs $179, and a 64 GB model is $199 (stick with the smaller model unless you play large Apple TV games). You can pre-order it on September 15, and it will be generally available a week later. The fourth-generation Apple TV remains on sale for $149. Although Apple said nothing about when tvOS 11 would be available, it seems likely to ship with iOS 11 and watchOS 4 on September 19th.
Whew! That’s a lot of new hardware from Apple in one day. If you’re considering buying an iPhone, Apple Watch, or Apple TV, you can now choose from new models with tempting features or time-tested older models at reduced prices.
