PEOPLES WHO REALLY WANT TO MAKE A BRIGHTER and CORRUPTION FREE NATION
Dear Sir or Madam:
SUB: world of no direct cash transaction.
To make the country free from corruption, basically the unaccounted cash transactions should be avoided. For that the following system may be adopted. We welcome your valuable suggestions.
In this system citizens of the country above 12 years of age will receive an instrument called process monitor (identification instrument capable of data processing with the aid of network services and the master computer. It will be integrated with Global Positioning System) with built in history card, camera and finger print scanner. Every citizen will be assigned with an identification number *** cell phone number with finger print details. Problems with the cell phone instrument will be immediately attended otherwise it will be replaced with another good working one with the same data drawn from the data bank of the master computer. Tourists from other countries will be given temporary instrument and their activities will be monitored continuously. Children under 14 years of age have to be taken care by parents or guardians. Peoples are doing mistakes because they believe that nobody notices. If peoples feel being watched they hesitate to do mistakes. Later the system can be modified to offer some degree of freedom.
The history card of the monitor consists of the following details and will be operated automatically from master computer through reliable networking systems.
1.Name, 2. Family history, 3. Identification number *** contact cell phone number (even though a person changes his/her name the identification number will not be changed), 4.

Type of transaction (details of work done and charges, reason for the transaction), 9. Net income, 10. Net expenses, 11. Tax payable to government (will be deducted automatically during every transaction and will be adjusted with the net income at a particular interval). 12. Marital status, 13.
