For now, the hardware requirements for Face ID are only found in the upcoming iPhone X. All other new iPhone models and all existing ones will retain Touch ID. Apple might choose to retain Face ID as a premium differentiating feature, but based on the company’s previous patterns of high-end feature rollouts, it will likely be in both new iPhone models in late 2018, and then in the iPhone SE at some point thereafter. It would seemingly also be likely for future iPad Pro updates, but perhaps not until the second quarter of 2018 or even mid-year.
The Auto-ID Center suggests a concept of a future supply chain that is based on the Internet of objects, . a global application of RFID. They try to harmonize technology, processes and organization. Research is focused on miniaturization (aiming for a size of mm/chip), reduction in the price per single device (aiming at around $ per unit), the development of innovative application such as payment without any physical contact (Sony/Philips), domotics (clothes equipped with radio tags and intelligent washing machines), and sporting events (timing at the Berlin marathon).
