This is a ready reckoner thread for those interested in facts.
However various governments continued with trials claiming that it would stop looting of booths.
A non-writable microchip is simple microchip in which the writing pin is programmatically or physically disabled.
The input comes from BU to CU via cables which can be easily manipulated.
The manupulatibility of wires is an aspect which most of the time is ignored.
They do a white box testing for expected results and not a thorough black box testing.
Saigal's research later laid ground for a book by @GVLNRAO on the issue of EVM hackability.
No BEL is planning to build at capacity in house.
Some like Germany, shifted to EVM's and then switched back to ballots.
The EVM which was hacked by Alex Heldermann and VV Rao in 2009 live on TV was a generation 2.
Hearing a petition filed by VV Rao the SC ordered in 2013 that all EVM's be fitted with VVPAT's.
How many machines does one have to manipulate in order to rig an assembly election?
Let's do some basic maths.
Each EVM's can hold up to 3000 votes however the number of voters in a booth is generally around 1200. Let's say 50% of these i.e 600 are manipulated to go in favor of a certain party.
Also remember that each vote added to someone is also one vote deducted from someone.
So, by manipulating 5 machines for 50% votes, the result can be completely altered.
Let's take an average of 180 booths per constituency. By manipulating 5 of these 180 the result will be completely different from what it could have been.
One doesn't have to rig 100% of the EVM's to win. One doesn't have to be entirely distracted to lose. 3% distraction is good enough.
That is all it takes to subvert Democracy.
They were supposed to be verifiable slips. That is what the acronym stands for. However the EC's unease in checking VVPAT's raises many questions.

They were found at a kabad shop in Andhra during one raid.
EVM's are supposed to be maintained by ECIL. However, ECIL hires private individuals to do the task.
