I’ve been giving more thought to the issue of how Apple might embed Touch ID into the display of the iPhone 8. So far, the various reports and rumors have focused on two possibilities: one hi-tech, one low-tech.
The hi-tech approach would be to embed a fingerprint reader beneath the display. We know from the sheer volume of Apple patents that Apple has plenty of ideas about how this might be achieved – but there’s a massive difference between a concept and a finished product.
