Pakistan should wait and watch though few things can be started now like opening bank accounts and digitization. Why would you pay bills by handing down cash and wasting your time. Why go to ATM, take out cash, manage it and pay grocers, electricity company or cab. Digital is the way to go. Less black money, more convenience.
Digitization will not happen just by internet and smartphone. You need complete eco system. It might be a good opportunity for IT start ups. Pakistan is a big economy. 16 % etc is too less. You already have CNICs, just open accounts and digitization.
See Kenya example.
