It was noted during the select committee that the future of our border is digital. There is a move away from paper-based cards in favour of utilising technology like smartphone apps and websites so that passengers can provide arrival information in a digital format. Again, this shows why it's appropriate to include detail about what information and how information is to be provided into specially drafted regulations. It ensures sufficient flexibility which will make the uptake of new technology a lot easier than if officials had to amend primary legislation each time technology changes.
