This is all such hilarious BS. These "analysts" have no reliable sources.
I called this out as soon as it started. They're talking about TouchID at the superficial, idiot level, without understanding all of the consequences should Apple have decided to truly replace the fingerprint scanner. It would be a HUGE amount of effort, likely requiring renegotiating agreements with partners and totally redesigning the system's hardware architecture. This is not something which Apple is going to decide within "weeks". Bull-****.
If Apple was going to replace TouchID or put it on the back of the phone, they would need to square that with ApplePay (which is an extremely important service). There are regulations governing how much liability card issuers have for fraudulent transactions based on your authentication method. For example, card issuers are potentially liable for fraudulent charges if they issue you with a magnetic stripe card with signature authentication, which are both easily copied. If you use a modern chip-and-PIN card, however, they are not liable. If you use a contactless card with zero authentication, once again they become liable (which is why such payments are limited to small amounts and will still occasionally ask for your PIN to authenticate). Similar considerations apply to the iPhone's Secure Enclave and TouchID. How liable would a card issuer be if they permitted & encouraged you to authenticate payments using an easily-duped facial recognition system?
That's the kind of thing a second-rate "analyst" doesn't think of; but you can bet Apple didn't forget about it.
Not only that, but the TouchID sensor has extremely tight, hardware-level integration with the Secure Enclave inside the iPhone's CPU (for security). Any switch to a camera-based system would require the same level of security. That's an extremely significant redesign of the system architecture, not that any of these "analysts" would appreciate that.
Remember how crazy Apple are about security? The TouchID sensor is locked to your device at the factory, in an effort to protect against government agents installing fake sensors which allow their own prints. They fought the courts and the FBI to avoid creating a backdoor to access a terrorist's iPhone. They can't stop harping on about privacy and security.
These people (who apparently have zero understanding of Apple or the iOS platform) are claiming that Apple has no idea what they want the next iPhone to be like, and are going to make a snap decision about replacing one of the most critical components of the device. Apparently, Apple wants to remove the home-button so badly, they are willing to compromise all other parts of the device, risk their hard-won reputation for security and privacy, your bank accounts and private information (including health information).
Bull. ****.
Maybe Apple are replacing TouchID (anything is possible) - but if they are, they are replacing it with something that has been extensively tested and proven reliable, and it would be in a system hardware architecture that was designed for that sensor. They're not deciding anything "within weeks".
