Beginning in 2024, visitors to the UK will require more advanced preparation than in the past

Beginning in 2024, visitors to the UK will require more advanced preparation than in the past. The U.K. is currently implementing a new Electronic Travel Authorization (ETA) system. The introduction of the ETA is a step toward the UK's goal of having fully digital borders by the year 2025.

In the U.S., visitors must also apply for a similar authorization before coming: the Electronic System for Travel Authorization (or ESTA), which is available to travelers from countries granted a Visa Waiver Program.

This will all eventually be merged with a digital ID, along with jab passports, social credit scores, and so forth.
