• Will this app support old phones that people can’t afford or don’t want to upgrade?
• What about rooted phones?
• What about phones that don’t run Android or iOS?
• Will people have the option of a physical hard copy? Would they have to pay for the privilege?
• Will it be optional (for now…) or forced on everyone? If optional, will some be excluded from many parts of society?
• Will it work offline?
• Will there be numerous bugs that prevent people from proving their right to be here, as there has been with the eVisa scheme?
• Will it be available in an open format, so that it is available to all and can be stored and verified using free software?
• Will the government spend money wisely on this project or syphon off millions to corrupt contractors?
• Will people be required to carry it at all times?
• Will storing all this information in a central location make it easy for to illegally share data between departments, as Musk did in the US?
• Will it start off just being used to verify your age and right to work, and gradually expand to all other areas of life including the ability to access content online?
• Would we be as comfortable with Reform having this centralised information as we would be with the current government?

Unfortunately, knowing the record of our government with both parties in power, I suspect it to be implemented in the worst possible way.
