these are good suggestions but there are still more suggestions. Like the all banks account, transactions through account, salary account should have only one unique number i.e. UID so that curruption level can be decrease.
People should get the UID when he/she born. which includes the date/time/day/month/year/geocode/locationcade etc information and that person has to carry that UID through out his life .... name is not manditory but UID.
everything is UID only like bank account, loan account number,employee number,rail pass number, even PF, FD, RD, Driving license, passport, rationing card, electricity bill watever which provides the identy of that person etc. should be connected to UID.
All public shoul have UID card which contains all above detail.... which is like other RF card.
All transaction is cashless. even a purchase of a chocolate of Rs 0.50 should be cashless.
Also all public places should contain the UID card reader so it identyfy number of people in india visited to the place.
its not so easy ..... but not impossible atall!
