Since they want to link aadhar to your persona and travel, what data is shared/stored with the authorities? 🤔 How will it work for people without an aadhar number? Is it an indian version of the chinese system in place at airports since about 10-15 years? (where they link your national ID to every travel step, including the fact that something was found in your handluggage at security...)
