This is just wishful thinking. They're not going to make all of the farm workers, many of whom have difficulty reading ANY language (let alone English), download an "app" and install it on their phone.
"In 2024, a significant portion of the UK adult population, approximately 8.5 million people (1 in 6), struggles with reading and writing at a basic level, according to The Reading Agency's 2024 report"
Maybe they'll have an exception for people who are more migratory in nature. In that event, I think we'll get to see a nice real-world example of a cyberpunk-style dystopia. "High tech, low life". The upstanding citizens will be surveilled, preyed upon by corruption, and will be running on a social credit score treadmill designed to work them to death. Meanwhile, a plucky band of rebel farm workers, who are free to work outside the system, will bring down the establishment and bring freedom to all. Roll credits.
