Apple's revival of Touch ID expected in 2021 iPhones, featuring an innovative in-screen fingerprint sensor.
In the ever-evolving world of technology, the tech industry is gradually moving away from traditional passwords. One of the key players in this shift is Apple, with rumours circulating about the potential inclusion of Touch ID in future Apple devices.
Apple analyst Ming-Chi Kuo, a well-respected figure in the Apple community, has predicted that an iPhone will be released in 2021 with both Face ID and Touch ID. This prediction is based on a report from 9to5Mac. The iPhone in 2021 will reportedly have a fingerprint reader built directly into its display, rather than in a Home button, as seen on the iPhone X, introduced in 2017, which was the last iPhone to include Touch ID.
The development of in-screen fingerprint sensor technology increases the likelihood of Touch ID being integrated into the Apple Watch. Apple has filed a patent for an in-screen fingerprint sensor that can take a scan from practically anywhere on the display, as opposed to current phones with sensors limited to tiny boxes typically located at the bottom of a device's display. This technology could be particularly useful in situations where Face ID isn't ideal, such as when the phone is lying flat on a table or when the user is wearing sunglasses.
For those who prefer Touch ID over facial recognition, it could serve as an alternative, secure method for logging into apps or making purchases online using an Apple account. The return of Touch ID via an in-screen fingerprint sensor could provide a secure form of local two-factor authentication.
However, it's important to note that predictions about the inclusion of Touch ID in future Apple devices are not definitive and should be taken with caution. The issues of power consumption, sensing area size, module thickness, and low production yields of ultrasonic sensors, which Apple is expected to use, are expected to be addressed by 2021.
If you're considering an upgrade, it might not be advisable to wait until 2021 for the potential inclusion of Touch ID. Ming-Chi Kuo suggests that Touch ID could potentially be added to the Apple Watch. For the foldable iPhone, predicted to be released around 2021, Ming-Chi Kuo predicts that Touch ID could be featured on a side power button instead of Face ID due to design constraints.
The ability to have both Touch ID and Face ID on the same device could be beneficial in a secure two-factor authentication system. The optical sensors used in phones like the OnePlus 7 Pro are considered somewhat less secure compared to the ultrasonic sensors Apple is expected to use.
In conclusion, while the return of Touch ID via in-screen fingerprint sensors is an exciting development, it's important to approach these predictions with caution. Apple's future in-screen Touch ID sensor is expected to be based on Qualcomm's ultrasonic fingerprint readers, similar to Samsung's Galaxy S10. As we move towards a passwordless future, it will be interesting to see how Apple continues to innovate in the realm of secure authentication methods.
