it can be the quickest way of establishing inheritance or can be used as proof of succession in digital form for starters, the use cases are there but they way it's been projected and marketed is simply stupid.
Of course, but inheritance require bit more process and documentation. One can always go to NADRA office and have a printout, or have the data emailed to relevant dpt.
Infect, now i see more crimes in future. I also find it unIslamic, to make private information of people available at finger tips, all what it takes is a NID card number. If you have a friend at NADRA you can have ID card number of any one. In every application form, there's NID card number mentioned..... WTF were they thinking?
I can tell you, with stunt of 'wife can know the about second wife of husband' is marketing technique of ruling elite, who is actually dancing on the tunes of enemies of Pakistan.
