haha... post se sirf ballot papers bheje jaate hain... vote caste karne ke liye facilitation ballot box use hota hai... usme sab ke voted ballot papers daal kar proper seal karke ..saare candidates ke representative + govt officers ka attestation le kar fir special messenger( not below the rank of nayab tehsildaar) ke through bheja jata hai ... this practice is since many years and is tried and tested one... only drawback is that it is resource consuming.
