The use of electronic voting machines became extremely popular during the first few years of this millennium. India started using voting machines in 2002; Ireland started testing them in 2002 and Brazil in 2005. The use of electronic voting machines has always been the topic of controversies and vulnerabilities. However, it continues to be in use at many countries in spite of the possibilities of tampering.
The Irish government spent nearly 50 million euro, buying 7000 electronic voting machines over the last decade. However, soon after testing them in 2002, it withdrew them due to security concerns. Though, India continues to use Electronic Voting Machines (EVMs) in spite of multiple proof-of-concept hacks.
Now, the Irish government wants to get rid of those 7000 useless voting machines and will float tenders for recycling or purchase of the useless machines. Apparently, the EVMs were never used, the Irish government spent a huge amount of money storing them, and now, and it is willing to sell them off for disposal after failing to find another country, which would buy them. It seems like EVMs are losing the trust of people and the sooner governments like India and Brazil stop using it, the fairer and lesser controversial their elections will be.
