Here’s how Apple could easily solve its Touch ID ‘problem’ on the iPhone 8

<p>I’ve been giving more thought to the issue of how Apple might embed <a href="https://9to5mac.com/guides/touch-id/" target="_blank" rel="noopener noreferrer">Touch ID[/url] into the display of the <a href="https://9to5mac.com/guides/iphone-8/" target="_blank" rel="noopener noreferrer">iPhone 8[/url]. So far, the various reports and rumors have focused on two possibilities: one hi-tech, one low-tech.</p>
<p>The hi-tech approach would be to embed a fingerprint reader beneath the display. We know from the sheer <a href="https://9to5mac.com/2017/03/28/iphone-8-fingerprint-sensor-ultrasonic-patent/" target="_blank" rel="noopener noreferrer">volume[/url] of <a href="https://9to5mac.com/2017/02/28/iphone-8-fingerprint-reader-embedded-in-display-patent-granted/" target="_blank" rel="noopener noreferrer">Apple[/url] patents <a href="https://9to5mac.com/2016/05/18/home-button-in-iphone-display-screen/" target="_blank" rel="noopener noreferrer">that[/url] Apple <a href="https://9to5mac.com/2016/05/18/home-button-in-iphone-display-screen/" target="_blank" rel="noopener noreferrer">has[/url] plenty of <a href="https://9to5mac.com/2016/10/04/touch-id-in-display-iphone-8/" target="_blank" rel="noopener noreferrer">ideas[/url] about <a href="https://9to5mac.com/2016/05/18/home-button-in-iphone-display-screen/" target="_blank" rel="noopener noreferrer">how[/url] this might be achieved – but there’s a massive difference between a concept and a finished product. Indeed, there’s a huge gap between a fully-working prototype and something that works in volume production. If the rumors are to be believed, Apple has struggled to achieve this.</p>
<p>The low-tech approach would be to take the same route as many Android brands and simply move the Touch ID sensor to the rear of the casing. I’ve discussed previously why I think this would be a <a href="https://9to5mac.com/2017/03/29/opinion-iphone-8-touch-id-sensor-rear-of-iphone/" target="_blank" rel="noopener noreferrer">terrible idea[/url], and the <a href="https://9to5mac.com/2017/04/28/bare-iphone-case-no-rear-touch-id-vertical-camera/" target="_blank" rel="noopener noreferrer">most recent[/url] reports <a href="https://9to5mac.com/2017/04/26/iphone-8-schematic/" target="_blank" rel="noopener noreferrer">do suggest[/url] Apple is <a href="https://9to5mac.com/2017/04/23/iphone-8-dummy-model-surfaces-with-edge-to-edge-display-no-rear-touch-id/" target="_blank" rel="noopener noreferrer">not taking[/url] this approach.</p>
<p>But it strikes me that there’s a third possibility here. What might be termed a ‘mid-tech’ approach …</p>
